Hello,,, well I am learning java in school and the teacher is terrible, I have a hw assignment I have no idea how to do.

I have to finish writing the code to this program. the question is.

"The BMI applet computes a persons body mass index. BMI Applet is defined as the weight, in kg divided by the square of the height, expressed in meters. A fragment of the BMI applet is show below.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.DecimalFormat;

public class Bmi extends JApplet
implements ActionListener
JTextField inputLbs, inputInches, displayBmi;

public void init()
JLabel labelLbs = new JLabel("Weight (lbs):", SwingConstants.RIGHT);
inputLbs = new JTextField(5);
JLabel labelInches = new JLabel("Height (inches):", SwingConstants.RIGHT);
inputInches = new JTextField(5);
JLabel labelBmi = new JLabel("BMI = ", SwingConstants.RIGHT);
displayBmi = new JTextField(5);
JButton go = new JButton("Compute");

Container c = getContentPane();
JPanel p = new JPanel();
p.setLayout(new GridLayout(3, 2, 5, 5));
c.add(p, BorderLayout.CENTER);
c.add(go, BorderLayout.SOUTH);

public void actionPerformed(ActionEvent e)
int lbs = Integer.parseInt(inputLbs.getText());
int inches = Integer.parseInt(inputInches.getText());
double bmi = calculateBmi(lbs, inches);
DecimalFormat df = new DecimalFormat("00.0");

private double calculateBmi(int lbs, int inches)
< ... missing code >

I have to supply the missing code for the calculateBmi method, which takes weight in lbs and hight in inches as arguments and returns the body mass index...

ANY ideas here thanks/..
