Java Code Help

[hava]

package Name --> Calculator

I created an abstract class Calc--> I had give some abstract method addition and subtract
public abstract class Calc
{
public abstract int add(num1,num2);
public abstract int sub(num1,num2);
}

I extended this Calc class in Operations class which should inherit the abstract method from Calc class and I implemented these both abstract methods in Operations class.
public class Operations extends Calc
{
public int add(int num1, int num2)
{
System.out.println("the result is");
return num1+num2;
}
public int sub(int num1, int num2);
{
System.out. println("the result is"):
}
}

So, these are the Abstract class and their respective implementation right... now I have to creare a TEST CASE fot these...So,
public class CalcTest
{
public static void main(string[] args)
{
----------------------;
---------------------;
----------------------;
}

Please fill the blanks so that the o/p of the program should be addition of two variables num1 and num2 and subtraction of num1 and num2.


[size=5]My guess:[/size]
So, I guess to pass the arguments here in the test case through command line so how to pass the variables and also I think we need to create an instance of the Operations class but I'm not sure I'm stuck here please help me with this simple JAVA code

Change abstract to interface and extend to implement
