Full-screen JFrame

I constructor

setExtendedState(MAXIMIZED_BOTH);

Eller:

import javax.swing.*;
import java.awt.*;

public class MyJframe extends JFrame {

    private Container _fContainer;

    public Container getContainer() {
        return _fContainer;
    }

    public void setContainer( Container _pContainer ) {
        _fContainer = _pContainer;
    }

    public MyJframe() {
        _fContainer = getContentPane();
        _fContainer.setLayout( new BorderLayout() );
        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
        setSize( d );
        show();
  }

    public static void main( String[] args ) {
        new MyJframe();
    }
}
