How do I determine if a class extends another class in Java?

Question

In Java how do I go about determining what classes a class extends?

public class A{
}

public class B extends A{
}

public class C extends A{
}

public class         


        

Answer 1

Yes, Class.getSuperclass() is exactly what you need.

Class c = obj.getClass();
System.out.println(c.getSuperclass() == Some.class);
