This program doesn't display the results :-(

Question

this program should output the sum,difference,product and quotient of two numbers.
i guess the computeQuotient is the wrong part..
import java.util.*;
public class MethodExample2
     static Scanner get = new Scanner(System.in);
     public static void main(String[] args)
          double sum,difference,product,quotient;
          double n1,n2;
          System.out.print("Enter the first number: ");
          n1 = get.nextInt();
          System.out.print("Enter the second number: ");
          n2 = get.nextInt();
          sum = computeSum(n1,n2);
          difference = computeDifference(n1,n2);
          product = computeProduct(n1,n2);
          quotient = computeQuotient(n1,n2);
          System.out.print("Sum: " + sum);
          System.out.print("\nDifference: " + difference);
          System.out.print("\nProduct: " + product);
          System.out.print("\nQuotient: " + quotient);
          System.out.println();
     public static double computeSum(double num1,double num2)
          return num1 + num2;
     public static double computeDifference(double num1,double num2)
          return num1 - num2;
     public static double computeProduct(double num1,double num2)
          double res = 0.0;
          for(double ctr = num1;ctr > 0; ctr--)
                    res = num2 + res;
          return res;
     public static double computeQuotient(double num1,double num2)//i guess this is the wrong part
          double res, ctr;
          for(ctr = 1; ctr >= 0; ctr++)
               res = num1 - num2;
               num1 = res;
          return ctr;
}

Dear Sir:
The ArithmeticException is RuntimeException, therefore it is unchecked exception.....
Here is my dumb program for your reference....
import java.util.*;
public class ScannerExp{
     static Scanner get = new Scanner(System.in);
     public static void main(String[] args){
     double sum,difference,product,quotient;
     double n1,n2;
     System.out.print("Enter the first number in double format: ");
     n1 = get.nextDouble();
     System.out.print("Enter the second number in double format: ");
     n2 = get.nextDouble();
     sum = computeSum(n1,n2);
difference = computeDifference(n1,n2);
     product = computeProduct(n1,n2);
     quotient = computeQuotient(n1,n2);
     System.out.print("Sum: " + sum);
     System.out.print("\nDifference: " + difference);
     System.out.print("\nProduct: " + product);
     System.out.print("\nQuotient: " + quotient);
     System.out.println();
     public static double computeSum(double num1,double num2)
          return (num1 + num2);
     public static double computeDifference(double num1,double num2)
          return (num1 - num2);
     public static double computeProduct(double num1,double num2){
          return (num1*num2);
     public static double computeQuotient(double num1,double num2){
return (num1 / num2);
use
jacvac ScannerExp.java
java ScannerExpthen input the number you want to compute....
Hope it is half right....
