What is pack method in java programming?

Answer 1

If your talking about when you are packing components in a JFrame for example, something along the syntax of:

public static void main(String[] args) {

GUIFrame frame = new GUIFrame();

frame.setLocation(100, 100);

frame.setTitle("This is a JFrame implementation");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.pack();

frame.setVisible(true);

}

If you mean something like this, then the pack() method simply crams all the components together, to make the smallest space in a frame. They can be useful if all you want is that, otherwise options such as the .setSize(int height, int length); are also available for specific sizes.
