Fraction class
Why wont this work ????
import java.util.*;
import java.io.*;
public class Fraction
{
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
{
Fraction num1 = new Fraction(2,10);
Fraction num2 = new Fraction(15,5);
Fraction num3 = new Fraction(24,18);
System.out.println(" " + num1);
System.out.println(" " + num2);
num3 = num1.add(num2);
System.out.println(" " + num3);
System.out.println("Addition = " + num1 + " + " + num2
+ " = " + num1.add(num2));
System.out.println("Multiplication = " + num1 + " * " + num2
+ " = " + num1.multiply(num2));
num3 = num1.subtract(num2);
System.out.println("Subtraction = " + num1 + "  " + num2
+ " = " + num1.subtract(num2));
System.out.println("Division = (" + num1 + ") / (" + num2
+ ") = " + num1.divide(num2));
}
}

What errors are you getting?
You're making a few Fraction objects. Do you have a class that has the Fraction constructor? The Fraction class looks like it should also have add(), subtract(), multiply() and divide() methods.

It would seem its the fractions themselves, the ones I have choosen there 9 errors.
Fraction.java:11: cannot find symbol

As Masher said, you do not have a constructor defined for your Fraction class which takes two ints as arguments. That will take care of your first 3 errors. You need to define the multiply, subtract, divide, and add classes, which explains the other six errors.

you're right I redid it and came up with this , works fine now. Thanks for the feedback guys .
import java.util.*;
public class Fraction
{
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
{
Fraction num1 = new Fraction(3,4);
Fraction num2 = new Fraction(2, 10);
Fraction num3 = new Fraction(1, 8);
System.out.println("Fraction : " + num1);
System.out.println("Fraction : " + num2);
num3 = num1.add(num2);
System.out.println("Fraction : " + num3);
System.out.println("Addition = " + num1 + " + " + num2
+ " = " + num1.add(num2));
System.out.println("Multiplication = " + num1 + " * " + num2
+ " = " + num1.multiply(num2));
num3 = num1.subtract(num2);
System.out.println("Subtraction = " + num1 + "  " + num2
+ " = " + num1.subtract(num2));
System.out.println("Division = (" + num1 + ") / (" + num2
+ ") = " + num1.divide(num2));
}
}

So what did you change?
That code looks exactly the same....
Additionally, you should use the [ code ] tags

You've posted the old one
Please use:[code] put your code here
and after your code put :[]
inside the [] put /code.
Code:
import java.util.*;
public class Fraction
{}
