Q. What will be the output of the following Java program?
interface calculate
{
void cal(int item);
}
class displayA implements calculate
{
int x;
public void cal(int item)
{
x = item * item;
}
}
class displayB implements calculate
{
int x;
public void cal(int item)
{
x = item / item;
}
}
class interfaces
{
public static void main(String args[])
{
displayA arr1 = new displayA;
displayB arr2 = new displayB;
arr1.x = 0;
arr2.x = 0;
arr1.cal(2);
arr2.cal(2);
System.out.print(arr1.x + " " + arr2.x);
}
}
