Question

Write a java program that creates two interfaces named test1 and test2. In interface test1 the member function is square. In interface test2 the member function is cube. Implement these two interfaces in "Arithmetic" class. Create one new class called ToTestInt in this class use the object of arithmetic class.

Answer 1

Java Code:

interface test1 //interface test1
{
abstract int square(int x);
}
interface test2 //interface test2
{
abstract int cube(int x);
}
class Arithmetic implements test1,test2{ //class Arithmetic
public int square(int x) //implementing square method
{
return x*x;
}
public int cube(int x) //implementing cube method
{
return x*x*x;
}
}
public class ToTestInt
{
   public static void main(String[] args) {
   Arithmetic a=new Arithmetic(); //creating an object of Arithmetic class
   int square=a.square(9); //using object of Arithmetic class to call square method
   int cube=a.cube(9); //using object of Arithmetic class to call cube method
       System.out.println(square); //printing the square result
       System.out.println(cube); //printing the cube result
   }
}

Output:

Note:

Please save the above program in a file name "ToTestInt.java" and then compile and execute it.

Please comment if you face any difficulty.
