Java Name Swing Applet

Question

I'm trying to make a java swing applet using NetBeans that will take a name like Joe Smith and change it to Smith, Joe . However, when I run my applet, it doesn't change the name. Can anyone help me figure this out?

private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) {
        String name = null;
        String strName = nameTextField.getText();
        if (name == "") {
            return;
        } else {
            outputLabel.setText(convertName(name));
        }
    }

    public static boolean hasComma(String name) {
        return name.indexOf(',') >= 0;
    }

    public static String convertName(String name) {
        if (hasComma(name)) {
            return name;

        } else {
            int index = name.indexOf(' ');
            String first = name.substring(0, index);
            String last = name.substring(index + 1);
            String newName = last + ", " + first;
            return newName;
        }
    }

// Variables declaration - do not modify                     
    private javax.swing.JLabel nameLabel;
    private javax.swing.JTextField nameTextField;
    private javax.swing.JLabel outputLabel;
    private javax.swing.JButton submitButton;
// End of variables declaration     

Answer 1

String strName = nameTextField.getText();

should probably be

String name = nameTextField.getText();

in submitButtonActionPerformed().

Answer 2

The method to compare strings is equals . Change code

name = nameTextField.getText();
if ("".equals(name) {
   return;
