find all classes and interfaces a class extends or implements recursively

Question

I was wondering if there was an easy way of determining the complete list of Types that a Java class extends or implements recursively?

for instance:

cla         


        

Answer 1

If I got your question right, you want to find all the superclasses (class and interface) of a specific class. If so you can check the following solution

to find the superclasses

        Class C = getClass();
        while (C != null) {
          System.out.println(C.getSimpleName());
          C = C.getSuperclass();
        }

to find the interfaces

        C = getClass();
        for(Class adf: C.getInterfaces()){

              System.out.println(adf.getSimpleName());
        }
