In JAVA,Briefly explain what the following listener code will does. Assume you have the following components.

JTextField input;

JLabel output;

The listener class is registered to input. The original text displayed in input is "Enter something here" and the original text displayed in output is "waiting".

public class InputFieldListener implements ActionListener {

        public void actionPerformed(ActionEvent e) {

              String inputText = input.getText();

              boolean correct = inputText.equalsIgnoreCase("something") ? true : false;

  output.setText(correct ? "you got it" : "not quite");

if(correct) {

                   input.setEditable(false);

              }

        }

   }   

Explanation / Answer

There is a InputField that listens to a listener such that :-

1. String inputText = input.getText(); //Whatever the user eneters comes in as inputText
2.boolean correct = inputText.equalsIgnoreCase("something") ? true : false; //If the user enters something in inputText , then correct will be true otherwise false

3. output.setText(correct ? "you got it" : "not quite"); //The Label will display as "you got it" if correct at statement 2 is true otherwise output will be "not quite"

4. input.setEditable(false); // if correct become true in statemnet 2 then the TextField is no more editable
