This seems like an incomplete question. I've come across a similar question, that is " Make an interface named num with two functions int add(int x, int y) and int diff(int x, int y) then make a class that implements that interface num. ". Here is the solution for this: interface num { int add(int x, int y); int diff(int x, int y); } class InterfaceByKalash implements num { int sum; int sub; public int add(int x, int y) { sum = x+y; System.out.println("The sum is = " +sum); return sum; } public int diff(int x, int y) { sub = x-y; System.out.println("The difference is = " +sub); return sub; } public static void main(String[] args) { Interface2015 obj = new Interface2015(); obj.add(2, 4); obj.diff(2, 4); } }
