Addition java program

Hello,
Please help me execute the below program. Integer value is not excepted by setText method.

import javax.swing.*;
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class Addition extends JFrame implements ActionListener
{
int num1, num2, total;
JButton b=new JButton("Submit");
JButton exit=new JButton("Exit");
JTextField t1=new JTextField(10);
JTextField t2=new JTextField(10);
JTextField tsum=new JTextField(10);
JLabel l1= new JLabel("Number 1");
JLabel l2= new JLabel("Number 2");
JLabel sum=new JLabel("Sum");
public Addition()
{
Container c=getContentPane();
c.setLayout(new FlowLayout());
c.add(l1);
c.add(t1);
c.add(l2);
c.add(t2);
c.add(sum);
c.add(tsum);
c.add(b);
c.add(exit);
exit.addActionListener(this);
try
{
num1=Integer.parseInt(t1.getText());
num2=Integer.parseInt(t2.getText());
total=num1+num2;
}
catch (NumberFormatException e)
{
Toolkit.getDefaultToolkit().beep();
}
setSize(200,200);
setVisible(true);
}
public void actionPerformed(ActionEvent ae)
{
String str=ae.getActionCommand();
if("Exit".equals(str))
{
System.exit(0);
}
if("Submit".equals(str))
{
tsum.setText(total); // Here is the issue//
}
}

Please ignore above program as that is pasted incorrectly.

Try using code tags 'code' and '/code' between square brackets [ ]

setText is a method of JTextComponent that accepts a String, not an int. Therefore, you have to convert 'total' to a String. Normally, you would use the toString() method, but because a primitive type doesn't have this, you should use something like tsum.setText("" + total), or better, the static toString method from Integer: tsum.setText(Integer.toString(total)).

Thank you sevn, the program compiles using tsum.setText(""+total) or tsum.setText(Integer.toString(total)); however in the application when I click on submit after entering number 1 and number 2 the sum field is empty.

Thank you Sven, the program compiles using tsum.setText(""+total) or tsum.setText(Integer.toString(total)); however in the application when I click on submit after entering number 1 and number 2 the sum field is empty.
