How can my application dispose or close a Frame from another Frame AWT? For exam

Go to all tips in Swing, AWT

Question: How can my application dispose or close a Frame from another Frame AWT? For example I press button and another frame disappears...

Answer: easy! Event handling procedure add following code for example,
if(e.getSource() == buttonOK){
frameName.dispose();
}

or

framename.setVisible(false);

Remember, last method will still keep frame object alive and waste memory.
And dispose() method releases all of the native screen resources used by this Window, its subcomponents, and all of its owned children. That is, the resources for these Components will be destroyed, any memory they consume will be returned to the OS, and they will be marked as undisplayable.

Go to all tips in Java Tools

Question: I used JProof free utility for code obfuscation to protect my code. It seems that application does not work properly...

Answer: Yes, you should be aware that code obfuscation in certain areas will cause troubles.
There are few cases when application's behavior may be affected:

  • When Reflection API functions used to access private and package fields and methods of any class;
  • When package classes accessed by name using Class.forName(String) call, and name of class to be loaded generated at run time from several parts;
  • When changed Java items (classes, fields or methods) are referenced from native code.
