Are Java Class objects unique / singletons? [duplicate]

Question

are Class-objects guaranteed to be unique in the JVM, are they Singletons? i.e. will

getClass() == getClass()

always hold true and is

a == b

true if and only if

a.equals(b)

where a and b are of type Class<?>?

Answer 1

You can have one singleton and/or class per class loader.

a.equals(b) is required to be true if a == b (except if a is null)
