JFrame resizing components

Newbie & Debugging Questions

Hey guys, I am pretty clueless with how GUI stuff really works but I had gotten it working for my game so far…Thing is I want to be able to make it so that when I resize the window all of my graphics and all resize along with it…Is there like a standard way of going about this?

Heres all my JFrame stuff


JFrame frame;

setMinimumSize(new Dimension(256, 224));
	  		setMaximumSize(new Dimension(500, 500));
			setPreferredSize(new Dimension(256, 224));
			frame = new JFrame("2DGAME");
			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
			frame.setLayout(new BorderLayout());
			frame.add(this, BorderLayout.CENTER);
			frame.pack();
			frame.setResizable(true);
			frame.setLocationRelativeTo(null);
			frame.setVisible(true);

And Here is my main Render method


  public void render(){
		BufferStrategy bs = getBufferStrategy();
		if(bs==null){
			createBufferStrategy(3);
			return;
		}
		Graphics g= bs.getDrawGraphics();
		//this is where you draw.
		stateStack.render(g);
		for(Entity e:GamePlayState.entities)
			e.Render(g);
		bs.show();
		g.dispose();
	}
