CSC300 / CSC402: Boxing, Equality, and Memory: Integer Boxing with valueOf

Integer x = Integer.valueOf(30);
Integer y = Integer.valueOf(30);

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

Explicitly calling Integer.valueOf(30).

Java will provide the canonical representation for integers close to 0.

The boxed object returned in each case is the same, because 30 is close enough to 0.
