weight = 0.00;

height = 0.00;




}


public void kiraBMI(double w,double h,String nama)
{


weight = w;

height = h;






B = weight/(height*height);


DecimalFormat fmt = new DecimalFormat("#.##");



JOptionPane.showMessageDialog(null, " BMI " + nama + " ialah : " + fmt.format(B));





}


public static void main(String[] args)
{



BMI B1 = new BMI();


String bilStr = JOptionPane.showInputDialog(null, "Sila masukkan bilangan pengguna : ");

int bil = Integer.parseInt(bilStr);


for(int a = 1; a<=bil; a++) {


String nama = JOptionPane.showInputDialog(null, " Sila masukkan Nama anda : ");


String weightStr = JOptionPane.showInputDialog(null, "Sila Masukkan Berat anda (KG) : ");

double w1 = Double.parseDouble(weightStr);



String heightStr = JOptionPane.showInputDialog(null, "Sila Masukkan Tinggi anda (CM) : ");

double h1 = Double.parseDouble(heightStr);


B1.kiraBMI(w1,h1,nama);






}






System.exit(0);

}

cari kod ni :

1. for(int a = 1; a<=bil; a++) {
   
2. 
   
3.                         String nama = JOptionPane.showInputDialog(null, " Sila masukkan Nama anda : ");
   
4. 
   
5.                         String weightStr = JOptionPane.showInputDialog(null, "Sila Masukkan Berat anda (KG) : ");
   
6.                         double w1 = Double.parseDouble(weightStr);
   
7.                
   
8.                         String heightStr = JOptionPane.showInputDialog(null, "Sila Masukkan Tinggi anda (CM) : ");
   
9.                         double h1 = Double.parseDouble(heightStr);
   
10. 
    
11.                         B1.kiraBMI(w1,h1,nama);
    
12. 
    
13.                        
    
14.                        
    
15.                 }

Copy the Code

kemudian tambahkan kod ni dibawah kod diatas:

1. JOptionPane.showMessageDialog(null, " Nama anda :" + nama + " /nBerat : "+w1+"/nTinggi:"+h1);
