Question

```
1 try
2 {
3 int first = Integer.parseInt( firstJTextField.getText() );
4 int second = Integer.parseInt( secondJTextField.getText() );
5 int result = first + second;
6 }
7
8 resultJTextField.setText( String.valueOf( result ) );
9
10 catch()
11 {
12 JOptionPane.showMessageDialog( this,
13 "Please enter valid integers", "Number Format Error",
14 OptionPane.ERROR_MESSAGE );
15 }
```

Answer 1

This code segment has two errors. First, there is a line of code between the try block and the catch block. This line must be moved inside the try block. Second, the catch block is not passed any exceptions to catch. The catch block should have one parameter of type NumberFormatException because that is the exception that is likely to occur in the try block.
```
1 try
2 {
3 int first = Integer.parseInt( firstJTextField.getText() );
4 int second = Integer.parseInt( secondJTextField.getText() );
5 int result = first + second;
6 resultJTextField.setText( String.valueOf( result ) );
7 }
8 catch( NumberFormatException exception)
9 {
10 JOptionPane.showMessageDialog( this,
11 "Please enter valid integers", "Number Format Error",
12 OptionPane.ERROR_MESSAGE );
13 }
```
