 JAVA Swing


Q.1) Write a java program to design a swing application that randomly changes the colour on button click

Code:

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;


public class Swing1 implements ActionListener {

    JFrame f;


    Swing1() {

        f = new JFrame();

        JButton a = new JButton("blue");

        a.setBounds(40, 100, 100, 40);

        a.setBackground(Color.BLUE);


        JButton b = new JButton("red");

        b.setBounds(150, 100, 100, 40);        

        b.setBackground(Color.RED);


        a.addActionListener(this);

        b.addActionListener(this);


        f.add(a);

        f.add(b);

        

        f.setSize(400, 500);

        f.setLayout(null);

        f.setVisible(true);

        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }


    public void actionPerformed(ActionEvent e) {

        if (e.getActionCommand().equals("red")) {

            f.getContentPane().setBackground(Color.RED);

        } else if (e.getActionCommand().equals("blue")) {

            f.getContentPane().setBackground(Color.BLUE);

        }

    }


    public static void main(String args[]) {

        Swing1 c = new Swing1();

    }

}


Output:


> Text Field

Code:

import javax.swing.*;


public class SwingExample {

    public static void main(String[] args) {

        JFrame f = new JFrame();

        JTextField textField = new JTextField();

        textField.setBounds(130, 100, 100, 40);


        JButton button = new JButton("Click Here");

        button.setBounds(130, 150, 100, 40);


        f.add(textField);

        f.add(button);


        f.setSize(400, 500);

        f.setLayout(null);

        f.setVisible(true);

    }

}


Output:


> Image

Code:

import javax.swing.*;


public class SwingExample {

    public static void main(String[] args) {

        JFrame f = new JFrame();

        JTextField textField = new JTextField();

        textField.setBounds(130, 100, 100, 40);


        JButton button = new JButton(new ImageIcon("C:\\Car.jfif"));

        button.setBounds(130, 150, 100, 40);


        f.add(textField);

        f.add(button);


        f.setSize(400, 500);

        f.setLayout(null);

        f.setVisible(true);

    }

}
