I want to resize and position a JFrame in Java. How can I achieve that?
To resize and position JFrame, use the Dimensions class. Here, we have set the bounds for the frame −
int width = 500; int height = 400; Dimension size = Toolkit.getDefaultToolkit().getScreenSize(); frame.setBounds((int) size.getWidth() - width, 0, width, height);
The following is an example to resize and poisiton a frame −
Example
package my;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.Toolkit;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame("Register!");
JLabel label1, label2, label3;
frame.setLayout(new GridLayout(2, 2));
label1 = new JLabel("Id", SwingConstants.CENTER);
label2 = new JLabel("Age", SwingConstants.CENTER);
label3 = new JLabel("Password", SwingConstants.CENTER);
JTextField emailId = new JTextField(20);
JTextField age = new JTextField(20);
JPasswordField passwd = new JPasswordField();
passwd.setEchoChar('*');
frame.add(label1);
frame.add(label2);
frame.add(label3);
frame.add(emailId);
frame.add(age);
frame.add(passwd);
int width = 500;
int height = 400;
Dimension size = Toolkit.getDefaultToolkit().getScreenSize();
frame.setBounds((int) size.getWidth() - width, 0, width, height);
frame.setVisible(true);
}
}Output
