GUI-Program penghitung kalori dan konverter (part 2)

ayoayooo lanjut lagi ngoding programnya yang di part 1..
sekarang aku mau ngasih coding yang buat frame kedua, nama filenya entry.java :


import javax.swing.JOptionPane;
public class entry extends javax.swing.JFrame {
private pria b;
private wanita c;
    /** Creates new form entry */
    public entry() {
        initComponents();
        b=new pria();
        c=new wanita();

Penjelasan lagi :
untuk frame pertama, aku sambungkan ke frame kedua, nah jika konsumen meng-klik tombol "pria" yang di frame kedua, maka akan ke frame selanjutnya, di frame ketiga (frame pria), jika meng-klik tombol "wanita", maka akan menuju ke frame keempat (frame wanita)
coding untuk frame wanita (wanita.java) dan frame pria secara keseluruhan sama, tapi ada perbedaan pada rumus penghitungan kalorinya, walaupun tampilan GUI-nya sama.
Nah untuk frame wanita, ganti saja bagian berwarna merah yang ada pada frame pria dengan coding ini :

 t=Double.parseDouble(tinggi);

 u=Double.parseDouble(usia);

bb=(t-100)-(0.1*(t-100));

kkb=65.52+(9.56*bb)+(1.7*t)-(4.77*u);

ta2.setText("Kebutuhan Kalori Basal anda adalah:\n"+kkb+" kkal (kilokalori)");
