Kodingnya :
public class cafe extends javax.swing.JFrame {
String namamakanan,namaminuman;
int hargamakanan,hargaminuman,total,bayar,kembalian,kembali;
    /** Creates new form cafe */
    public cafe() {
        initComponents();
    }
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                        
// TODO add your handling code here:
 total=hargaminuman+hargamakanan;
    txttotal.setText(String.valueOf(total));  
}

// TODO add your handling code here:

    }
    txthmin.setText(String.valueOf(hargaminuman));
}                                        

private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {                                        
// TODO add your handling code here:
    dispose();
}                                       

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                        
// TODO add your handling code here:
    bayar=Integer.parseInt(txtbayar.getText());
    total=Integer.parseInt(txttotal.getText());
    kembalian=bayar-total;
    txtkembali.setText(String.valueOf(kembalian));
}                                       

private void cbmakananActionPerformed(java.awt.event.ActionEvent evt) {                                         
// TODO add your handling code here:
    String namamakanan;
    namamakanan=cbmakanan.getSelectedItem().toString();
    if(namamakanan.equalsIgnoreCase("Burger"))
    {
        hargamakanan=15000;
    } 
    else if(namamakanan.equalsIgnoreCase("Kacang"))
    {
        hargamakanan=5000;
    }
    txthmak.setText(String.valueOf(hargamakanan));
}                                        

private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {                                        
// TODO add your handling code here:
   cbminuman.setSelectedIndex(0);
    cbmakanan.setSelectedIndex(0);
    txthmin.setText("");
    txthmak.setText("");
    txttotal.setText("");
    txtbayar.setText("");
