I found this Q. in mock Exam

interface TestA {
String toString();
}

public class Test implements TestA{
public static void main(String[] args){
System.out.println("hello");
}
}

If, we implement an interface, this is necessary that we implement methods of that interface. But here this not happening. Is this due to toString() method of Object class?

Yes, you do not need to implement toString() in class Test because it is already implemented in class Object.
