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.
Lets Do Step by Step Touchable shop Pos
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.
public void mouseClicked(MouseEvent e) {
if(e.getSource() == lblBanana){
qty = Double.parseDouble(JOptionPane.showInputDialog("Enter Qty"));
df = (DefaultTableModel)tblTable.getModel();
name = "Banana";
price = 2.40;
System.out.printf("%.2f%n", tot = qty * price);
df.addRow(new Object []{
name,
price,
qty,
tot
});
Double sum = 0.0;
for(int i=0; i < tblTable.getRowCount(); i++)
{
sum = sum + Double.parseDouble(tblTable.getValueAt(i, 3).toString());
}
System.out.printf("%.2f%n", sum);
items = tblTable.getRowCount();
System.out.println(sum);
System.out.println(items);
txtTot.setText(Double.toString(sum));
lblItems.setText(Integer.toString(items));

}Calculate the Balance
public void cal()
{
double tottal = Double.parseDouble(txtTot.getText());
double pay = Double.parseDouble(txtPaid.getText());
double bal;
if(tottal < pay)
{
bal = pay - tottal;
txtBalance.setText(Double.toString(bal));
}
else
{
JOptionPane.showMessageDialog(null, "Not Valied Money ");
}
}Design the Bill
public void bill()
{
System.out.println("Bill button clicked");
System.setProperty("file.encoding", "UTF-8");
String total = txtTot.getText();
String pay = txtPaid.getText();
String bal = txtBalance.getText();
DefaultTableModel model = (DefaultTableModel) tblTable.getModel();
// Set the font size
txtbill.setFont(new Font("Arial Black", Font.PLAIN, 10));
txtbill.setText(txtbill.getText() + " ___________________________________________________\n");
txtbill.setText(txtbill.getText() + " DeviJames \n");
txtbill.setText(txtbill.getText() + " Welcome to our shop \n");
txtbill.setText(txtbill.getText() + " ___________________________________________________\n");
// Heading
txtbill.setText(txtbill.getText() + " Product\tPrice\tQty\tAmount\n");
for (int i = 0; i < model.getRowCount(); i++) {
String pname = (String) model.getValueAt(i, 0);
String price = model.getValueAt(i, 1).toString();
String qty = model.getValueAt(i, 2).toString();
String amount = model.getValueAt(i, 3).toString();
txtbill.setText(txtbill.getText() + " " + pname + "\t" + price + "\t" + qty + "\t" + amount + "\n");
}
txtbill.setText(txtbill.getText() + "\n");
txtbill.setText(txtbill.getText() + "\t" + "\t" + " Subtotal : " + total + "\n");
txtbill.setText(txtbill.getText() + "\t" + "\t" + " Pay : " + pay + "\n");
txtbill.setText(txtbill.getText() + "\t" + "\t" + " _______________ "+ "\n");
txtbill.setText(txtbill.getText() + "\t" + "\t" + " Balance : " + bal + "\n");
txtbill.setText(txtbill.getText() + "\n");
txtbill.setText(txtbill.getText() + " ___________________________________________________\n");
txtbill.setText(txtbill.getText() + " THANK YOU COME AGAIN \n");
}Paste the code inside the Calculate Button
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String tot = txtTot.getText();
if(tot.isEmpty())
{
JOptionPane.showMessageDialog(null, "Total is Empty ");
}
else{
cal();
}
}
Paste the code inside the Print Button
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
// Print Bill
String pay = txtPaid.getText();
String bal = txtBalance.getText();
if(pay.isEmpty() && bal.isEmpty())
{
JOptionPane.showMessageDialog(this, "Paid and Balance is empty ");
txtPaid.requestFocus();
}
else{
try {
bill();
txtbill.print();
} catch (PrinterException ex) {
}
}
}Paste the code inside the Finish Button
private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {
df.setRowCount(0);
txtTot.setText("");
txtPaid.setText("");
txtBalance.setText("");
txtbill.setText("");
lblItems.setText("");
