[RESOLVED] placing objects problem

[Justa Lol]

		Button1 = new JButton("Button1 ");
		Button1.setSize(100, 30);
		Button1.setLocation(300, 100);
		frame.add(Button1);
		Button2 = new JButton("Button2 ");
		Button2.setSize(100, 30);
		Button2.setLocation(200, 100);
		frame.add(Button2);
		Button3 = new JButton("Button3 ");
		Button3.setSize(100, 30);
		Button3.setLocation(100, 100);
		frame.add(Button3);

i use that code, the problem is that button3 will cover everything while button 1 and 2 will go where i told them to go... like button3 somehow will become the background... can someone tell me how to fix that?

edit:

if i made it

the Button2 = new JButton("Button2 "); and Button1 = new JButton("Button1 "); and so on in top it would work
