The Touchable Shop POS (Point of Sale) system is a sophisticated software solution developed using Java. Designed specifically for fruit shops, this system efficiently manages sales and transactions, ensuring smooth and streamlined operations. With its user-friendly interface and robust functionality, the Touchable Shop POS system is an essential tool for modern fruit retailers.
The system shall be able to select the relevant Fruit types.
Step 1: implement MouseListener
public class Bill extends javax.swing.JFrame implements MouseListener
Step 2: set the addMouseListener(this) in to each label. write it inside the constructor.
public class Bill extends javax.swing.JFrame implements MouseListener {
public Bill() {
initComponents();
lblBanana.addMouseListener(this);
lblPoires.addMouseListener(this);
lblApple.addMouseListener(this);
lblPineapple.addMouseListener(this);
lblPomme.addMouseListener(this);
lblMango.addMouseListener(this);
} after implemented the MouseListener it ask to implement all the abstract method of MouseListener.you must implement it.write code inside the mouseClicked event.
