How create methods to receives custom arguments?

There are many characteristics interesting about the JDK 5.0 than had not been used. An example of this are Variable Arity methods, sometimes referred such as varargs methods. Prior to JDK 5.0, if you wanted to pass an arbitrary set of arguments to a method need to pass an array of objects, but in JDK5.0 thanks to varargs can pass a sequence of arguments. For example the PrintStream class uses this characteristics in one its printf methods such as you can see below:

public PrintStream printf(String format, Object... args)

The second argument denoted by three points represents the argument may be passed as an array or as a sequence of arguments, exists one restriction about the position of arguments which say that the arguments variable must be the last parameter. Bellow can see two examples using one and two parameters respectively.

How to remove or disable the Minimize, Maximize and Close Button of JFrame?

Yesterday a friend question me how can i remove or disable the minimize, maximize and close buttons of frame? Here shows some possibilities that could be a solution.

  • The first alternative is use a JWindow instead of a JFrame which does not have those three buttons.
  • The second alternative could be use JInternalFrame instead of a JFrame.
  • The third alternative is use the setUndecorated() method to disable the decorations to this frame and later decorate with a dialog style. The only problem is that the close button don't remove so you must disable its function such as can see below

  • The last alternative could be disable the close and resizable buttons such as can see bellow.

I believe there are more solutions, but for me are the most easy and utils...
