CSC300 / CSC402: Boxing, Equality, and Memory: Integers Close to Zero

Integer x = 30;
Integer y = 30;

x=30, y=30
                  x==y : true
   Objects.equals(x,y) : true
           x.equals(y) : true

This is like what Java does with string interning -- boxed integers close to 0 are given a canonical representation.

Again, this is for efficiency.
