  • What is the command-line input to produce the javadoc?

    - by Bernard
    After writing all the comments inside the code about the javadoc such as /** * This method compares the student's answer to the standard answer * @param ans The student's answer * @return True for correct answer; False for incorrect answer */ boolean compareAnswer(int ans); I guess it starts with : javadoc [optionss] [packages|files] I'm not sure what is the regular or default [option] and how can I say to produce it in my current home directory?

Any suggestions as to why this occurs on Linux (RedHat Enterprise Linux)?

  • sqlite insert into: do the column names have to match?

    - by P a u l
    (This question is specific to SQLite3, but it may be common to all SQL I don't know.) This doesn't seem to work. Is it because the column names don't match? (If they match, it works.) If this is true, how can I select from a different field in the source table? INSERT INTO [ImagePoint] (ImageID, PointID, X, Y) SELECT Image2ID, PointID, X, Y FROM Point

  • Generic solution to deselect buttons in java

    - by Hectoret
    In a set of radio buttons of the same group, only one can be selected at the same time. I would like to have the same behaviour with a normal button. Imagine there's a row of 3 buttons. When a button is selected it changes: but.setSelected(true) and the other two buttons should be NOT selected: but.setSelected(false) Now, is there a generic, simple and clean solution to accomplish that in Java (Swing) ?

  • Protecting from crashes (beyond bounds) with [object objectAtIndex:]

    - by Tom
    Hi! I'd like to know if there's a way to verify if an index exists before getting it. So it'd be way to protect my code against: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (0)' Like in PHP you can do: isset($object[10]); and it'll return true if it exists. Is there such a method in Objective-C/Cocoa? Thanks!
