I cant seem to get this working,

import javax.swing.JOptionPane;
public class Main_1 {
public static void main(String[] args) {

String choice;
String choice1, choice2, choice3;
double num1;
double num2;
double num3;
int totals;

choice1 = JOptionPane.showInputDialog("Enter Grade 1");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 1");
}
while ( !choice.matches("[0-9]+" ) ){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 1");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 1");
}}
num1 = Double.parseDouble (choice1);
double result1 = methodone(num1);
choice2 = JOptionPane.showInputDialog("Enter Grade 2");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 2");
}
while ( !choice.matches("[0-9]+" ) ){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 2");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 2");
}}
num2 = Double.parseDouble (choice2);
double result2 = methodtwo(num2);
choice3 = JOptionPane.showInputDialog("Enter Grade 3");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 3");
}
while ( !choice.matches("[0-9]+" ) ){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 3");
while (choice == null){
JOptionPane.showMessageDialog(null,"Error, Numbers only");
choice = JOptionPane.showInputDialog("Enter Grade 3");
}}
num3 = Double.parseDouble (choice3);
double result3 = methodthree(num3);
double tot = methodtotals(result1, result2, result3);
}
//------------------------------------------------------------------------------
public static double methodtotals(){
JOptionPane.showMessageDialog(null,"Results"+result1+""+result2+""+result3);
}
//------------------------------------------------------------------------------
public static double methodone(double x){
return (x * 0.3);

You don't really expect us to debug your code for you, do you?
I'd gladly accept a mere 1 exagram of gold (99.999% pure, of course) for such a service.

What doesn't work? Does it compile? If it does, what happens when you run it?
Especially when the choices are null? Is your choice of choices correct?

That's like saying: My car just isn't working right. Fix it, without me telling you what the symptoms are. I expect you to drive the car around, honk the horn, turn on the washers, etc, etc, etc, until you find some kind of problem.
