menambahkan jumlah porsi

hi saya sedang membuat aplikasi menu restoran sederhana menggunakan netabeans tetapi ketika di jumlah porsi mengalami kendala .

Screenshot (362).png

seharusnya jumlah porsi menjadi 3 tetapi tidak terisi.

public class Restoran extends javax.swing.JFrame {

String jns1, jns2, jns3, jns4;

    int hS=50000, hL=75000, hB=40000, hSp=45000, total=0, jlh, bayar, uang, kembalian;

    /**

     * Creates new form Restoran

     */

    public Restoran() {

        initComponents();

    }





    private void resetMouseClicked(java.awt.event.MouseEvent evt) {

tfNama.setText(""); // del text input

         outNama.setText("Nama Pemesan : ");

         cbS.setSelected(false);

         cbL.setSelected(false);

         cbB.setSelected(false);

         cbSp.setSelected(false);

          tfjml1.setText("");

          tfjml2.setText("");

          tfjml3.setText("");

          tfjml4.setText("");

           outjumlah.setText("Jumlah porsi  : ");

         tajenis.setText("");

         outtotal.setText("");

         tfbayar.setText("");

         outkembali.setText("");

    }



private void jButton2MouseClicked(java.awt.event.MouseEvent evt) {
        //menampilkan nama pemesan
        outNama.setText("Nama Pemesan : "  +tfNama.getText());
        //menampilkan jumlah porsi
    int jumlah = Integer.parseInt(tfjml1.getText()) + Integer.parseInt(tfjml2.getText()) + Integer.parseInt(tfjml3.getText()) + Integer.parseInt(tfjml4.getText());
outjumlah.setText("Jumlah Porsi  : " + jumlah);


       if (cbS.isSelected() == false && cbL.isSelected()==false && cbB.isSelected()==false && cbSp.isSelected()==false){
       JOptionPane.showMessageDialog(null, "Makanan Belum Dipesan","Warning",JOptionPane.WARNING_MESSAGE);

       }

       else if(cbS.isSelected()&&cbL.isSelected()&&cbB.isSelected()&&cbSp.isSelected()){
            jns1 = cbS.getText();
            jns2 = cbL.getText();
            jns3 = cbB.getText();
            jns4 = cbSp.getText();

            tajenis.setText(jns1+"\n"+jns2+"\n"+jns3+"\n"+jns4);

            //menghitung total bayar
            total = (hS + hL + hB + hSp);
            jlh = Integer.parseInt(tfjml1.getText());
            bayar = total * jlh;

            //menampilkan total bayar
            outtotal.setText(String.valueOf(bayar));
             }
        else if(cbS.isSelected()&&cbL.isSelected()&&cbB.isSelected()){
            jns1 = cbS.getText();
            jns2 = cbL.getText();
            jns3 = cbB.getText();

            tajenis.setText(jns1+"\n"+jns2+"\n"+jns3);

            //menghitung total bayar
            total = (hS + hL + hB );
            jlh = Integer.parseInt(tfjml1.getText());
            bayar = total * jlh;

            //menampilkan total bayar
            outtotal.setText(String.valueOf(bayar));
             }
