WTF Java? Why Not Overload == for Java.lang.Long?

This particular quirk also holds true of, say, Ruby or Python:

    256 is 256         # True
    (2**50) is (2**50) # False

albeit without Java's fear of operator overloading and the counterintuitiveness it causes.

Comparison works as expected in Ruby Have checked in ruby 2.1.2p95

code:

> (250).class #=> Fixnum > (250) == (250) #=> true > (2100).class #=> Bignum > (2100) == (2100) #=> true

Comparisons work, but Ruby's == isn't the same as Java's; what I was referring to was

    250.object_id == 250.object_id         # true
    (2**70).object_id == (2**70).object_id # false
