Why is this possible in Java: this.getClass().getClass().getClass()....etc

Question

Why is this possible in Java:

this.getClass().getClass().getClass().getClass()...

Why is there this infinite recursion?

Just curious.

Answer 1

There's no infinite recursion here: getClass() returns a java.lang.Class object, which is itself a java.lang.Object object, hence it supports getClass() method. After the second call to getClass() you are going to get the same result, no matter how many times you call getClass().
