Answer 1

int is primitive type.This itself having value but Integer is object and it is having primitive int type inside to hold the value. You can do more operations like compare,longValue,..more by Using wrapper Integer.

== for Integer will not work the rang above -128 and 127. Integer hold cache value upto this range only in memory. More than this range you have to equals() method only to check Integer wrapper class.

equals() method will check the value stored in the reference location.
