public class Bmi extends JApplet
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));
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");
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/..

well what exactly don't you understand? The formula for the calculation is given at the top. I'm sure you can write that down, and converting it into java isn't too hard at all. You need to write down the formula in java, using the variables that are supplied as parameters to the method. Then you simply need to return the result.

he's blaming his teacher for his inability to go to lectures/not drink so much/learn some java/get enthusiatic enough (about the education that (s)he's paying for) to learn on his/her own..
or something :/
java isnt hard, even if your teacher sucks.. youre probably just telling yourself that because youre finding it hard, and hence, switching off your brain when in lectures.. I dont doubt that some teachers do suck, very much.. but that shouldnt hold you up any, because YOU are doing the learning, and there are other resources than your teacher to rely on.. when you start work your boss isnt going to spoon feed you everything you need to know about the job, so best get some research done, get some books out of the library (or buy some) about learning java, and sit down and really think about it..
