Simple swing programs

2. import java.awt.Color;
import javax.swing.*;
public class FirstSwing {
public static void main(String arr[])
{
JFrame f=new JFrame();
JButton b= new JButton("click");
b.setBounds(130,100,100,40);
f.getContentPane().setBackground(Color.RED);
f.setBackground(Color.red);
f.setSize(500, 500);
f.add(b);
f.setLayout(null);
f.setVisible(true); }}

3. JButton
import javax.swing.*;
public class ButtonExample {
public static void main(String[] args) {
JFrame f=new JFrame("Button Example");
JButton b=new JButton("Click Here");
b.setBounds(50,100,95,30);
f.add(b);
f.setSize(400,400);
f.setLayout(null);
f.setVisible(true);
}
}

4. JLabel
import javax.swing.*;
class LabelExample
{
public static void main(String args[])
{
JFrame f= new JFrame("Label Example");
JLabel l1,l2;
l1=new JLabel("First Label.");
l1.setBounds(50,50, 100,30);
l2=new JLabel("Second Label.");
l2.setBounds(50,100, 100,30);
f.add(l1); f.add(l2);
f.setSize(300,300);
f.setLayout(null);
f.setVisible(true);
}
}

5. JTextField
import javax.swing.*;
class TextFieldExample
{
public static void main(String args[])
{
JFrame f= new JFrame("TextField Example");
JTextField t1,t2;
t1=new JTextField("Welcome to Javatpoint.");
t1.setBounds(50,100, 200,30);
t2=new JTextField("AWT Tutorial");
t2.setBounds(50,150, 200,30);
f.add(t1); f.add(t2);
f.setSize(400,400);
f.setLayout(null);
f.setVisible(true);
}
}

6. JText area
 import javax.swing.*;
 import java.awt.event.*;
 public class TextAreaExample {
 JLabel l1,l2;
 JTextArea area;
 JButton b;
 TextAreaExample() {
 JFrame f= new JFrame();
 l1=new JLabel();
 l1.setBounds(50,25,100,30);
 l2=new JLabel();
 l2.setBounds(160,25,100,30);
 area=new JTextArea();
 area.setBounds(20,75,250,200);
 b=new JButton("Count Words");
 b.setBounds(100,300,120,30);

 f.add(l1);f.add(l2);f.add(area);f.add(b);
 f.setSize(450,450);
 f.setLayout(null);
 f.setVisible(true);
 }

 public static void main(String[] args) {
 new TextAreaExample();
 }
 }

7. Write a program in swing to add two
numbers
+
RESULT

8. public class Test1 implements ActionListener{
JFrame f ;
JTextField t1;
JTextField t2;
JLabel l1;
JButton b;
Test1()
{
f = new JFrame();
t1 = new JTextField();
t2 = new JTextField();
l1 = new JLabel("Result");
b = new JButton("+");
t1.setBounds(90, 50, 150, 30);
t2.setBounds(90 ,80,150,30 );
l1.setBounds(90, 140, 150, 30);
b.setBounds(90, 200, 100, 30);
f.setSize(600,400);
f.add(t1);
f.add(t2);
f.add(l1);
f.add(b);
b.addActionListener(this);
f.setLayout(null);
f.setVisible(true);
}

9. Add event
public void actionPerformed(ActionEvent e) {
int a = Integer.parseInt(t1.getText());
int d = Integer.parseInt(t2.getText());
int c = 0;
if (e.getSource().equals(b)) {
c = a + d;
System.out.println(c);
l1.setText(String.valueOf(c));
}
}

10. Add main
public static void main(String ar[])
{
Test1 t =new Test1();
}
