Catch without try error

I would like to get sum results from two textfields. I wanted a way to return nill in the result textbox. Why is the following code throwing "cath without try" error. Where am I wrong.Please assist.

private void AddButton4ActionPerformed(java.awt.event.ActionEvent evt) {
  try
   {
    int x = Integer.parseInt(FirstNumberTextField.getText());
    int y = Integer.parseInt(SecondNumberTextField.getText());
    ResultTextField1.setText((x + y)+"");
   {
   catch(Exception e)
   {
       ResultTextField1.setText("");
   }       
}

You have a { instead of a } at the end of the try block. This puts the catch block inside it.

The brace before the catch block must be closing brace }, but you've written another open brace {. In fact all blocks (if, else, try, catch, finally, while, for, etc.) always come in balanced sequences of {}

You have one opening brace too many:

private void AddButton4ActionPerformed(java.awt.event.ActionEvent evt) {
  try
   {
    int x = Integer.parseInt(FirstNumberTextField.getText());
    int y = Integer.parseInt(SecondNumberTextField.getText());
    ResultTextField1.setText((x + y)+"");
   } // <-- This one was wrong.
   catch(Exception e)
   {
       ResultTextField1.setText("");
   }       
}

You've got an open brace at the end of your try block instead of a closing brace.

   {
   catch(Exception e)

should be

   }
   catch(Exception e)
