JVM caches Integers and Longs, what about int and long

I read that Integer and Long class have its private collections for caching purposes, that mean that if I create two variables Integer a, b = 1, both would be the same objects as for "==" check.

What about int a,b = 1 - these are only primitives, can we call them objects? Are they also cached somehow in Integer class or JVM?

No, they're not cached and you can't call them objects.

It doesn't make sense to cache primitives, since there's no object creation involved.
