• Lesson 1-1 code is correct?

  Hi all.

  I just started watching a course and have finished all the chapters of lesson 1, no homework and quiz.

  So we in Lesson 1-1 example usage of lambda expressions (with my method createStudentsList() to fill the list):

  Students list < student > = createStudentsList();

  Double highestScore = 0.0;

  for (s student: students) {}

  If (s.getGradYear () == 2011) {}

  If (s.getScore () > highestScore) {}

  highestScore = s.getScore ();

  }

  }

  }

  It compiles and works.

  But the proposed changes by using lambda expressions does not work:

  Students list < student > = createStudentsList();

  Double highestScore = student

  filter (new predicate < student > () {})

  public boolean test (Student's t) {}

  return t.getGradYear () is 2011;

  }

  })

  .map (Mapper new student, < Double > () {})

  public Double extracted (student s) {}

  Return s.getScore ();

  }

  })

  . Max();

  saying "the filter method (new predicate < student > () {}) is undefined for the type List < student >" and "Mapper cannot be resolved to a type.

  Even the latest version of the code does not compile:

  Students list < student > = createStudentsList();

  highestScore = student

  filter (student s-> s.getGradYear () == 2011)

  .map (student s-> s.getScore ())

  . Max();

  with "syntax error, insert ';' to complete the statement" for the two statements of student.

  I managed to make it work with this approach:

  Students list < student > = createStudentsList();

  Double highestScoreL = student

  . Stream()

  filter (s-> s.getGradYear () == 2011)

  .mapToDouble (s-> s.getScore ())

  . Max()

  . getAsDouble();

  I do wrong or just missed sth sth important? Sorry for the question so long - it is because as pieces of code .

  BTW I use Eclipse March 4.5.0 and jdk1.8.0_51 if that matters.

  There is problem with your code. I fixed your code and it would be:

  Student s0 = new Student(2014, 685);

  Student s1 = new Student(2014, 675);

  Student s2 = new Student(2014, 635);

  Student s3 = new Student(2014, 985);

  List of students of = Arrays.asList (s0, s1, s2, s3);

  Stream studentStream;

  studentStream = students.stream ().

  filter (new predicate() {}

  @Override

  public boolean test (Student's t) {}

  return t.getGradYear () is 2014;

  }

  });

  Stream highestScoreStream = studentStream.map (new function() {}

  @Override

  public Double apply (student s) {}

  Return s.getScore ();

  }

  });

  HighScore = highestScoreStream.max of in option (new comparator() {}

  @Override

  public int compare (Double d1, d2 Double) {}

  Return d1.compareTo (d2);

  }

  });

  Double highestScore = highScore.get ();

  System.out.println (highestScore);

  Make sure and tell me if you don't get anything. This is the detailed code pre JDK8 average. Now you can write it as functional programming.

  and Yes... The video code is just for us to understand. It is not syntactically correct as map is not a FunctionalInterface in JDK8.

• Developer of sql Oracle - code beautifier

  Hi all

  Where is beautifier code of oracle sql Developer (if any)?

  My version is 4.0.3.16

  It (Ctrl + F7) works for me in 4.0.3 as well in a spreadsheet and the PL/SQL code editor.  According to the SQL Formatter settings, sometimes the action Format has no effect. For example, a piece short single line of SQL may already be formatted according to the parameters.  However, if the Format is something, then Ctrl + F7 should also have the same effect.

  Watch Tools > Preferences > shortcut keys to see if the Format is associated with Ctrl + F7. If it is, with Format work but not the shortcut key, then something can be altered in your user settings.

• Trying to create a pivot in Oracle 10.2.0.4

  I have the following query that retrieves data from three tables, SORPCOL, SORDEGR and STVSBGI. SORPCOL houses of prior information college for some applicants for admission, SORDEGR houses degree information, including VMI associated prerequisites colleges, and STVSBGI is a validation table housing codes of the institution and the names of the colleges.
  
  SELECT SORPCOL_PIDM,
  SORPCOL_SBGI_CODE,
  STVSBGI_DESC,
  SORPCOL_TRANS_RECV_DATE,
  SORPCOL_TRANS_REV_DATE,
  SORPCOL_ADMR_CODE,
  SORPCOL_ACTIVITY_DATE,
  SORDEGR_GPA_TRANSFERRED,
  SORDEGR_HOURS_TRANSFERRED
  OF SORPCOL, SORDEGR, STVSBGI
  WHERE SORPCOL_PIDM = 123456
  AND SORPCOL_SBGI_CODE NOT IN ('CUMGPA')
  AND SORPCOL_PIDM = SORDEGR_PIDM
  AND SORPCOL_SBGI_CODE = SORDEGR_SBGI_CODE
  AND SORPCOL_SBGI_CODE = STVSBGI_CODE
  
  The output that I get from it is fine and is as follows:
  
  PIDM SBGI STVSBGI_DESC TRANS_RECV_DATE TRANS_REV_DATE ACTIVITY_DATE SORDEGR_GPA_TRANSFERRED SORDEGR_HOURS_TRANSFERRED ADMR
  123456 008000 unknown College 2011-07-10 00:00:00 CLT1 07/10/2011 09:39:50 0.750
  123456 008002 unknown College two 07/10/2011 00:00:00 CLT1 07/10/2011 09:39:50 1,800
  
  Each applicant may have several previous colleges, but there is not a defined maximum number of previous institutions, they may have. The only thing in SORPCOL which can be a unique identifier is the SBGI code, but it would be different for each prior order, by pidm, and there is 8500 College different codes in STVSBGI, an applicant could have one of them. There is not a SORPCOL or SORDEGR field that creates a number of associate with each prior college, either, such as 1, 2, 3, etc. They want that this programmed to shoot up to 10 previous colleges. If I can get help doing the first two, I think I could find a way to add more.
  
  What the user wants to look like the output is the following:
  
  PIDM COLL 1 CODE COLL 1 DESC COLL 1 TR RECV DT COLL 1 TR REV DT COLL 1 ADMR, COLL 1 LAW DATE COLL 1 GPA XFR 1 HR XFER COLL COLL 2 CODE COLL 2 DESC 2TR RECV DT 2 DT COLL REV TR COLL COLL 2 ADMR, COLL 2 LAW DATE COLL 2 GPA XFR COLL 2 HR XFER
  123456 008000 unknown College 07/10/2011 CLT1 07/10/2011 008002 0.750 unknown Coll 2 10/7 / 2011 CLT1 07/10/2011 1,800
  
  Does anyone have suggestions on how this might be accomplished? It seems in Oracle 11 that it wouldn't be too hard, but I don't know about 10.2.0.4.
  
  Thank you very much
  Michelle

  In my view, that the following example is close to what you are looking for:

• Is this a bug in Dreamweaver? Because the code is correct! Please advise!

  Hey coders.

  I'm pretty new to Dreamweaver, but have a decent understanding of the code and if I ever got stuck I usually figure out on my own, but today are not the case.

  My problem is: when I enter the code it didn't display correctly in my workspace, the slice falls completely down, when it should have been in the middle. But when I make it with the browser, it displays correctly! ???

  You can see my site here's progress to:

  http://www.topvizstudio.com/webproblem/index.html

  or you can download sliced HTML and Image here:

  Please help, it is just killing me, I've already lost 2 hours trying to figure it out!

  Thank you!

  Design view is not 100% reliable.  What matters most is how your pages make in all the major browsers (IE 6,7,8, FF, Opera, Safari/Chrome...)

  The last picture is 500px wide and floating to the left, and yet the previous images are quite a bit more small. This leads me to think there isn't enough available on the page width to account for this installment.

  In addition, I do not understand why you are using may inline styles both in your HTML code.  This will make it much more difficult lifestyle changes later because your styles are not separated from the content.

  You must delete a semicolon after your image file names.

  Finally, your code has a typical beginner problem called division-it is.  In contrast to the provisions based on a table where each element is contained in a table cell, CSS layouts, there is no need to place each element on the page within its own division. In fact, it is often best if you do not.  Less increase in the code.
