Answer 1

수동으로 크기를 제어해서는 안됩니다. 사용자가 크기를 조정하려는 경우 어떻게해야합니까 ?? 당신은 쓸모없는 계산을해야만한다. 자바는 레이아웃 매니저를 사용하여 행복하게 해줄 것이다.

Answer 2

JFrame frame = new JFrame(); 
frame.setLayout(null); 
frame.setSize(600, 400); 

JPanel panel1 = new JPanel(); 
panel1.setBounds(0, 0, 400, 200); 
panel1.setBackground(Color.YELLOW); 
panel1.setLayout(null); 

JPanel panel2 = new JPanel(); 
panel2.setBounds(400, 0, 200, 400); 
panel2.setBackground(Color.RED); 
panel2.setLayout(null); 

JPanel panel3 = new JPanel(); 
panel3.setBounds(0, 0, 600, 400); 
panel3.setBackground(Color.BLACK); 
panel3.setLayout(null); 

panel3.add(panel1); 
panel3.add(panel2); 
frame.add(panel3); 

//YOU CAN USE LAYOUT = NULL TO MANUALLY POSITION YOUR PANELS 
//IT IS BEST TO USE LAYOUT MANAGERS, BUT SETTING THE POSITIONS MANUALLY IS THE EASIEST 
//SPECIALLY IF YOU WILL JUST .setResizable(false)
