A Simple Message Box In Java

Monday 10 February 2014



To do this job Two java components are needed
  1. jButton1
  2. jLabel1

Now we have to put this code on jButton1ActionPerformed
As written below

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)
{
int a=JOptionPane.showConfirmDialog(mainPanel,"Have a Good Day","Please Press Ok or Cancel",JOptionPane.OK_CANCEL_OPTION);
if(a==0)
{
    jLabel1.setText("You HAve Pressed Ok");
}
else if(a==2)
{
    jLabel1.setText("You Have Pressed Cancel");
}
else if(a==-1)
{
     jLabel1.setText("Dont Play a Joke with me");
}
else
{
    jLabel1.setText("Wow");
}
}
