How to place a JButton at a desired location in a JFrame using Java

Question

I want to put a Jbutton on a particular coordinate in a JFrame. I put setBounds for the JPanel (which I placed on the JFrame) and also setBounds for the JButton. However, they dont seem to function as expected.

My Output:

This is my code:

import java.awt.Color; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel;  public class Control extends JFrame {      // JPanel     JPanel pnlButton = new JPanel();     // Buttons     JButton btnAddFlight = new JButton("Add Flight");      public Control() {         // FlightInfo setbounds         btnAddFlight.setBounds(60, 400, 220, 30);          // JPanel bounds         pnlButton.setBounds(800, 800, 200, 100);          // Adding to JFrame         pnlButton.add(btnAddFlight);         add(pnlButton);          // JFrame properties         setSize(400, 400);         setBackground(Color.BLACK);         setTitle("Air Traffic Control");         setLocationRelativeTo(null);         setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);         setVisible(true);     }      public static void main(String[] args) {         new Control();     } } 

How can place the JButton at coordinate (0, 0)?

Answer 1

Following line should be called before you add your component

pnlButton.setLayout(null); 

Above will set your content panel to use absolute layout. This means you'd always have to set your component's bounds explicitly by using setBounds method.

In general I wouldn't recommend using absolute layout.
