Require a method of an instantiated class to be called

Question

Let's say I have this code:

public class MyClass {
    public void doSomething(int value) {

    }
}
public class MyNewClass {
    public static void main(String args[]) {
        MyClass myClass = new MyClass();
    }
}

Would it be possible to get a compiler error that doSomething(int) from MyClass has not been called in MyNewClass? I know realistically you would put that method in the constructor but this question is out of curiosity.

The closest you can come to this is using code coverage tools. Providing you have a full set of unit tests, they will allow you to identify, for example, which methods are never called. I can't recommend one library in particular but there are plenty available.
