Print the name of the object

Hi all

I am new to Java, I would print the name of the object below apprenticeship program.

Output should look like

velo1 rate: 40 speed: 12 gear: 1
bike2 Cadence: 50 speed: 60 Gear: 2

What are the changes that I have to do to get the desired result.

Hi Raghu,

Here, you already have the object, in order to have the name of the object. All you need is to print name. For example, you can pass the name of object as a parameter to the printStatus() method and you're done. Code changes are below:

void printStatus(String name)// here String parameter is added
      {
          System.out.println(name + " Cadence :" + cadence + " speed :" + speed
                  + " Gear :" + gear);
      }

And inside the method main calls the method printStatus() with the name of the object.

bike2.printStatus("bike1 ");      // calling with the name of object
bike2.printStatus("bike2 ");

  • HP Officejet 7610: On computer, the screen is an object that is round. When it is printed, the object's oval.

    Help please. My printer is a HP Officejet 7610. On my computer Windows 10 screen, a document image is 'round '. When the document is printed, however, the image becomes an "Oval". I need to be round as the document. What could cause this do? How can I solve this problem? I don't know if it's a problem of printer or a computer problem. Any & all explanations would be greatly appreciated. Thank you!

    Larry,

    I thought you would like to know that my problem is solved. Round objects are now actually round instead of oval. I looked in your advice re: Adobe Reader & eventually remove it completely.

    My main problem, however, was that my resolution is set too low. Don't know how it changed to weak, but he did change. I must have done something that caused his change but don't know what. In any case, changed the setting in place for my computer and voila! Everything is back to normal.

    Understand your willingness to help.

  • Track of the names of the objects for stocks?

    Can someone provide organizational practices, that I can use to keep track of the many names given to objects that will be used in advanced Actions? Here's something that you would print with a screenshot? I can see how it's easy to lose track of the names as I build in Captivate.

    Thank you

    I always label each object, group to be used in Advanced/shared actions. Match by naming: I'll start each name with 1/2 characters identifying the nature of the object: T_ (for containers of text), Bt (for buttons), SB (for form buttons), I_ (for images), Gr_ for groups.

    Don't you know that you can filter in the drop-down lists in the advanced Actions dialog box and in the settings dialog box. Type a sequence of characters that appear anywhere in the name, and the list is filtered on the objects with this sequence. Example: type "co" and objects with name 'v_counter', 'T_Code', 'I_cow' will remain in the list.

  • Change the name of the object of a report

    I use this command in my script

    oMyObjects.Item ("Text1"). Text = Data.Root.ChannelGroups ("PhotoSet" & I). Properties ("Caption"). Value

    That's fine, it works very well.

    But I'm not happy with the object that has the name of Text1, I wish it were PartNumber.

    How can I change this?  I can't find it on the report tab.

  • Can I change the name of the object to measure report

    Hi, I'm new to TS! Can I change the name of the object to measure report? Who can help me. Thanks in advance!

    «Under normal circumstances, I finished the test USE, TS generated the report like this "report [13-29-06] [4F492CAB04] [2012-11-28] .html'.»

    Can I change something, when TS report will like this"report [13-29] [4F492CAB04] [2012-11-28] .html' without seconds!

    One way is to modify the process template.

    Locals.ReportFilePath saves the name of the report. You can access only functions (such as SerachAndReplace) to create the new ReportFilePath.

    In the model sequential process step determine the path of the report file provides the path to the report file using the report options settings. Custom code can be placed after this step.

    The methods below are for Windows 7 - Vista and XP are similar.

    Vista references apply to Windows 7.

    You probably need to recharge the device drivers and any software control of the 'IF' camera, there is
    everything for Windows 7.

    Login as an administrator.

    Double-click Control Panel / Device Manager - Imaging - writing down of the brand and model of camera.
    on this subject and on the tab of the driver is version. Now, click on update drivers (who are unable to do anything as MS
    is far behind the pilots of certification). RIGHT click on the camera - UNINSTALL - REBOOT - it
    will update the driver stack.

    Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera
    software (if not more recent get the same).

    Download - SAVE - go to them and RIGHT CLICK - RUN AS ADMIN - reboot after each driver.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers to 7 (update drivers manually using the methods above is preferred

  • Is it possible the give a name to an object of decoration?

    Hello world

    I would like to change the colors of some squares of decoration (not too sure what is the English word for this but I don't know who are indicators or commands and objects that serve just decoration) on my front pannel. The problem I have already met a year ago was that, when I add a new object of decoration, all the parameters related to the my provious objects are shifted... And it's very annoying when constantly adding new items...

    Has this changed? Is it possible to give a name to an object so that it not be moved...?

    If there is no change, I have to use the backgroung of an indicator, but it will seem not as good...

    Thank you very much
