Coffee Shop Pos System using Java

The Coffee Shop Pos System using Java. The project is built to manage sales and transactions. To make a new transaction, fields such as: Rice Type and Drink type, qty needs to be selected. If you like to learn point of sales systems step by step, this is the right place to learn from the beginning. In this tutorial useful for making a point of sales system for small a shops.

The system shall be able to select the relevant Drink type and Rice type.

Step 1: write code  inside the constructor of class.

    public pos() {
        initComponents();
          
        jTable1.setForeground(Color.YELLOW);
        jTable1.setBackground(Color.BLACK);
        jTable1.setOpaque(false);
        jTable1.setFont(new Font("Serif", Font.BOLD, 16));         

    }
DefaultTableModel model = new DefaultTableModel(); // it is use to create the jtable model object.

 Create the Variable

int qty;
int price;
String name;

Paste the Code inside the Add Button

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

int sum = 0; 
if(lblfried.isSelected())
{  
   int qty = Integer.parseInt(txtfqty.getValue().toString());
   
   model = (DefaultTableModel)jTable1.getModel();
   model.addRow(new Object[]
    {         
        lblfried.getText(), // name 
        12,                 // price  
        qty,// quantity <- replace this 
        qty * 12           // total
    }); 
   
}
if(lblfish.isSelected())
{
   int qty = Integer.parseInt(txtfish.getValue().toString());
    model.addRow(new Object[]
    {         
        lblfish.getText(), 
        15,                   
        qty,               
        qty * 15
    });  
 
}
if(lblchicken.isSelected())
{
   int qty = Integer.parseInt(txtcqty.getValue().toString());
    model.addRow(new Object[]
    {         
        lblchicken.getText(), 
        25,                   
        qty,               
        qty * 25
    });    
   
}   

if(lbltea.isSelected())
{
   int qty = Integer.parseInt(txttea.getValue().toString());
    model.addRow(new Object[]
    {         
        lbltea.getText(), 
        35,                   
        qty,               
        qty * 35
    });    
   
}   


if(lblcoca.isSelected())
{
   int qty = Integer.parseInt(txtcola.getValue().toString());
    model.addRow(new Object[]
    {         
        lblcoca.getText(), 
        25,                   
        qty,               
        qty * 25
    });    
  
}   


if(lblcoff.isSelected())
{
   int qty = Integer.parseInt(txtcoffee.getValue().toString());
    model.addRow(new Object[]
    {         
        lblcoff.getText(), 
        25,                   
        qty,               
        qty * 25
    });    
   
}   
            for(int i = 0; i <jTable1.getRowCount(); i++)
               {
                   
                   sum = sum + Integer.parseInt(jTable1.getValueAt(i, 3).toString());
                   
               }
               txtsub.setText(Integer.toString(sum)); 
    }
