Values of Java primitive types are not objects, but for each primitive type there is a wrapper (or "boxed") class that is a subclass of java.lang.Object.

The primitive types we will discuss, and their corresponding wrapper classes are:

Integers

Integers are numbers used for counting.
The primitive integer type is int, and its wrapper class is java.lang.Integer.
Write an integer constant literal as a sequence of digits without a comma.
The integer operators are:

Operator	Meaning
+	addition or unary plus
-	subtraction or unary minus
*	multiplication
/	integer division
%	modulus (remainder)

Their precedence order is:

unary +, unary -

*, /, %

+, -

Shortcuts, e.g. += and ++

Autoboxing makes the difference between ints and Integers almost invisible.

See java.lang.Math for some functions provided by the Java library.
