• Lesson 1 homework load: cannot access the java.lang

  I made all facilities and followed all the steps of Lesson1 for the java ME course for Raspberry Pi, but when trying to load the homework examples in the zip file I get the following in Netbeans 8.0.2 error message (and many more mistakes, but I guess that it is the number one key).

  Cannot access the java.lang

  Fatal error: could not find the java.lang package in the classpath or bootclasspath

  I tried to load the files to work from home with 'file', 'open project' and navigating to the folder with the file build.xml. What I am doing wrong? How these files must be loaded?

  Simple examples with "to go". ' and 'destroy... '. "impression of the lessons worked well, both on the output of the PC console as the Bill pro forma raspberry connected.

  Note, I'm using version 8.1 of ME incorporated, SDK and Plugins currently available on the Oracle website.

  Thanks for your help.

  It seems that the SDK was not established as a platform target in the properties of your project by a reason any (for example, older has not installed SDK as a platform project properties).

  Check following:

  1. menu Tools > Java platforms. "Oracle Java (TM) Platform Micro Edition SDK 8.1" should be here as a platform CLDC peresent. If you have not, add it here manually.

  2 menu popup on your project > properties-> platform: you select here as aplatform SDK and the existing mechanism. Note, in the event that your project contains a platform/device this dialog box will be filled with the default (s) value, but you have to press the "OK" button here to apply this default assignment.

• Methodically, debugging homework 3 part 3 coding

  I am convinced that homework 3, part 2 has been completed and the customer (ECPG - s) ran successfully data display in the putty window.

  If the material and the Raspberry IP configuration is stable. I would like to simplify the troubleshooting steps encoding for reading GPS data, perhaps display the data received in each method and have a map of what it should look like. Are there more references than the "events-data-message-doc' or maybe a part of the video to help with this?

  OR, if a person can offer a suggestion for the not to step in each of the sections of code using "System.out.println", points of rupture or a good system for tracking data through each method (readDataLine, geRawData, getPosition, getVelocity, etc.) is easier to see where the code has problems. To start receiving data, the class AdaFruitGPSUARTSensor must be properly implemented, that close at the end of part 3 and after my coding problem. Perhaps, I placed some features in a fault method. I'm having difficulty to assess that.

  I'm not sure what you mean by 'events-data-message-doc' and I don't recall videos specifically on debugging that presenters have used the println command to display data.  However, there are two ways to debug using netbeans.

  First of all, make sure that you have used putty to connect and then the Java ME 8.1 on the IPD has begun and that you have connected your RPi in connection of Device Manager. Nothing will work if you don't do these things first.  You're right, there are two ways to debug.  1. use println.  2. use breakpoints.

  The easiest way is to use println statements.  I use readDataLine as an example.

  Here is my readDataLine method:

  protected String readDataLine() throws IOException {}

  String dataLine = null;

  dataLine = serialBufferedReader.readLine ();

  If (dataLine.startsWith("$")) {}

  return the data row;

  } else {}

  Returns a null value.

  }

  }

  To print the string dataLine, first place your cursor on a line after that the variable data is defined.

  Then type safe (this is a shortcut to the println command).  Don't hit back.  Just type s o u t)

  Then click on the tab key, it develops the shortcut in a full range of valid code.  Your cursor will now be inside a set of quotes.

  Type something like this 'dataLine = "+ data line inside the parens competence.

  Now, your code will look like this:

  dataLine = serialBufferedReader.readLine ();

  System.out.println ("dataLine =" + dataLine);

  If (dataLine.startsWith("$")) {}

  This indicates Java to print the characters ' dataLine = "in the console, then print dataLine.". "  Notice how I put a space before and after the '=' for readability.  You can ignore these spaces if you want.  In fact, you could shorten the whole line and print System.out.println (dataLine); If you don't want to have any explanatory text.

  Now, run the code.  When your code hits this spot dataLine will print on the console.  You can view the console in at least 3 places: 1. The Putty window.  2. in the EmbeddedExternalDevice1 window, click Exit.  3. in the window out into Netbeans.  If you don't see it, click/Window/Output, or press Ctrl and 4 at the same time.  I like the method 3 the best because I can do this in Netbeans without having to open other windows and cluttering up my screen.

  The next method is to use breakpoints.  It's more complicated, but much more powerful.

  To set a breakpoint, see the grey border immediately to the left of your code.  On my Netbeans, this gray area has line in numbers because I said Netbeans to display line numbers (view/show line numbers).  If you have not enabled, the gray area will have nothing in it.  Click in this box to the left of the line you want to add a breakpoint to.  If a red square appears, you have set a breakpoint.

  To activate the breakpoint, you must run your code in debug mode.  If you run the code in the normal Run mode, no breakpoints will activate.  To run code without breakpoints, I click the Green Run button upwards in the toolbar.  Click on project/running, or press F6.  These methods do not enable breakpoints.

  To run in debug mode or click the icon to the immediate right of the Green Run button (it has a picture of a breakpoint and a small green triangle of race), click Debug/Debug project or press Ctrl F5.  Each of these methods should start your project in debug mode.  It runs like it did when you run the project normally, but he's stopping at breakpoints, and it may work a little more slowly because it is now followed for breakpoints.

  Once the breakpoint is reached, the three windows should appear in your code: watches, Variables, breakpoints.  Variables window shows the variables that are in scope at the breakpoint.  If you put a breakpoint on the line after the variable data is defined, you can see the contents of the row of data in the variable window.  Note: If you put a breakpoint on the line of data in row = serialBufferedReader.readLine (); you don't WILL NOT read a value of dataLine because it has not been defined until this statement has been executed.  So move your breakpoint to the next line.

  There is much more to say about debugging.  Here is a link a page describing more information about debugging using NetBeans.

• Wire-2nd week homework 1 clarification

  The duties States:

  The second thread starts print messages when the first thread is on an odd interval (ending 5): 12:05, 12:15, etc. This thread will print a message every 30 seconds. This thread illustrates the use of a task interval spaced - for example, a job where you want to collect readings over a period of time to illustrate a rate of change.

  
  

  Just so I'm clear, the second thread is triggered to begin printing of messages once and only once, namely when the first thread reaches the first minute '5' end (i.e. 5% min == 0), Yes?  After that, he keeps on printing messages every 30 seconds?  There is no trigger "switch off", OK.

  
  

  Thank you

  
  Brent S

  
  

  Brent & Henry - salvation

  The way I wrote homework, it is certainly open to interpretation!

  My solution is consistent with the interpretation of Henry.  Only works the second thread that displays a message every 30 seconds

  5 minutes (10 messages).

  The output looks like this (example):

  Departure time: 14:05:35

  Time: 14:10

  Time: 14:15

  But it is not really a good or bad way.  The point of the homework is exploring using wire or timers.

• Q:help with TimerTask in homework #1

  Hello

  so I am trying to create myself a TimerTask (part of homework...) and I'm stuck because I'm not understand what is happening now. I created an imlet that begins the timertask (or at least I think I have). The code that makes it looks like (this part of my IMlet):

  @Override

  public void startApp() {}

  startDate = new Date();

  System.out.println ("HomeWork1IMLet started:" + startDate.toString () .substring (0: 19));

  Timer = new Timer();

  timerTask = new TTask();

  Timer.Schedule (timerTask, 0, 2000);

  }

  My timertask class looks like this (short version):

  import java.util.Date;

  java.util.TimerTask to import;

  SerializableAttribute public class TTask extends TimerTask {}

  @Override

  public void run() {}

  Date startStopDate = new Date();

  System.out.println("1");

  System.out.println ("In TTask wire..." + executionTime (startStopDate));

  System.out.println("2");

  System.out.println ("Mins:" + getRunMinute (startStopDate));

  System.out.println("3");

  If (startSubThread (startStopDate)) {}

  System.out.println ("In TTask (run) wire Tjohoo");

  } else {}

  System.out.println ("In TTask (run) no tjohoo");

  }

  }

  private int executionTime (Date runDate) {}

  return Integer.parseInt (runDate.toString () .substring (0: 19));

  }

  private int getRunMinute (Date runDate) {}

  return Integer.parseInt (runDate.toString () .substring (14, 16));

  }

  Private boolean startSubThread (Date runDate) {}

  int minute = Integer.parseInt (runDate.toString () .substring (15, 16));

  return (minute == 5);

  }

  }

  Now the problem is if I use this class the only thing I get in the console is as follows:

  [INFO] [SECURITY] iso = 1:Application HomeWork1IMlet | atael assigned to the customer "not reliable."

  HomeWork1IMLet started: kills Apr 01 02:31:34

  1

  And I don't understand why I never go further down the code? I want to say that I never see 2 or 3 in the console or on the RPi? No idea what Miss me, I'm probably missing something basic...

  Thank you

  Andy

  Hi Andy -.

  The problem is in this line:

  return Integer.parseInt (runDate.toString () .substring (0: 19));

  You try to parse (as an integer) almost the entire Date String.  The result is a runtime, NumberFormatException exception.

  If you replace the code with a try/catch, you will see the error:

  	int result = 0;
  	try {}
  	result = Integer.parseInt (runDate.toString () .substring (0: 19));
  	} catch (NumberFormatException ex) {}
  	System.out.println ("NumberFormatException:" + ex);
  	}
  	return the result;

  Hope this helps,

  Time to learn because it is the reason of your dilemma.

  CS6 is available in two flavors: Cloud and non-Cloud.

  Cloud is only available by subscription, and the version number is "13.1.something".

  The perpetually licensed (no-Cloud, a Creative Suite framework) version is what you and the version number is "13.0.something" (yours is 13.0.1).

  "Copy CSS" is available in the Cloud (13.1). If you don't have access to the CSS copy with the version you are using. You must run the version of cloud.

• How iTunes respect my custom artist/Album homework?

  Hello!  I am trying to transfer my iTunes music library (more 11 000 songs) from the hard drive of my old laptop (a Windows machine) to my MacBook Air (MacOS 10.10.5, iTunes 12.3.2) by copying the iTunes Media folder: Music on the old hard drive to the iTunes Media: automatically add to iTunes on my Mac folder.  In the process, I expected to "re-brand" many files to do things like making the composer the artist under which classical compositions are deposited, for example, Bach all in an artist called Bach folder (instead of have it all scattered on in different folders corresponding to the performers) and have all the tracks on the CD to several albums in a single title of the album folder (and not in separate folders for) each drive), etc.  I did already a lot of this work by hand and worked to do things in the Album artist file: unknown unknown, when I accidentally opened iTunes and it began to the add to iTunes process (which I now want to 'Cancel', if possible).  It was my pants up, but then I noticed that all the work I did for the files to "reposition" in the records of the artist and the Album of my choice is not met: in the iTunes Media folder: Music, records that I had deleted have been recreated and files I had put elsewhere were released in the old folder structure , which obviously I don't like, or I wouldn't go to so much trouble to change it.  So is there a way to achieve my goal, i.e., customize the artist and Album of the folder names and content, preferably before all be imported into iTunes, and iTunes will respect and preserve?  Thank you!

  You shouldn't do like that.  Instead, you need to take your entire iTunes folder (and not just your iTunes Media folder) on the Windows PC and put it on the MacBook Air to replace its existing iTunes folder.  iTunes on the new MacBook will look like in iTunes on the old Windows PC, with all songs and data, such as playlists, ratings, play count, date added, etc.  The existing "metadata" will be the same as before, and you can continue to work to better organise your songs in iTunes.

  If you do as you describe, your NEW iTunes library on the MacBook will be more disorganized, and you won't have your playlists (all the songs will be new songs in a new library).  This new iTunes library won't know anything about the old iTunes library.  iTunes doesn't care of the existing folder structure when you import the songs (iTunes considers new songs) to a new iTunes library.  By using the default settings, iTunes keeps the folder iTunes Media organized, based on what you see in the list of iTunes window name song music library (more Track #), Album name and artist name.

  The procedure to transfer your complete iTunes folder is described in this document

  Back up your iTunes library by copying to an external drive - Apple Support

  To sum up, the first step "consolidates" your iTunes media files (from where they are currently stored on your drive), in the designated folder iTunes Media (in your iTunes folder).  All your media files may already be store here.  Second copies of step ("backup") this folder full iTunes (which includes your iTunes library database file very important), on an external drive.  The third step "restores" that backs up the iTunes folder, in your case, for the new MacBook.  With iTunes not running, you replace the existing folder to iTunes of the MacBook with the old Windows PC.  When you run iTunes, it uses this iTunes folder; you see the same iTunes library.

  What antivirus/antispyware/security products do you have on the machine? Be one you ALREADY had on this

  If no joy there's something blocking perhaps.

  IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

  IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK

  Close and restart IE or IE with no addons

  not better?

  IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install

• My move slider to the other lines and paragraphs and letters when typing e-mails and do their homework.

  As a first step, if you see letters where they aren't suppose to be, I'll put this word in brackets. If you don't see everything, it happens sometimes. I've had this laptop for 18 months. Motherboard has been replaced three times. Cursor and letters move to other lines and paragraphs themselves. This problem is annoying, especially when I do the assignments in class. Is their a fix for this problem, or what?

  Please help, my time is precious.

  Uncle Midgy

  Your laptop has a touchpad?  Chances are good that you are accidentally in touch with her all by tapping and activating the latter and that moves the cursor (and before you notice it, you typed a letter whenever the cursor moves towards).  This happened to me until I bought a separate mouse and disable the touchpad - then the problem has disappeared.

  Some touchpad controls (usually located under the start menu / control panel / mouse have commands to disable the touchpad while typing.)  See if that is the case with yours and if so, activate the function, and it can be useful.  If you do not have the service contact the computer manufacturer to obtain the latest device drivers touchpad and install (and update the drivers for the keyboard while you're there just in case it is the source of the problem, but I think it is the touchpad) - they contain the function as an upgrade.  Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need to get drivers (and you do it for your keyboard and touchpad), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.

  I hope this helps.
