What kind of Exception occurred?

user640 Published in July 15, 2018, 9:20 pm

I tried to create a test ClassCastException:

In line 1: it prints out class cast exception as I expected
In line 2: it just prints exception.RuntimeExceptionTest$1B@7852e922 (RuntimeExceptionTest is my class name). I wonder what kind of exception here?

 try {
            class A { }
            class B extends A {}
            class C extends A {}
            A objA = new B();
            System.out.println((C)objA); // Line 1
            System.out.println((A)objA); // Line 2
        } catch (Exception e) {
