Operator	Description
+, +=	Addition (a + b, arithmetic)
-, -=	Subtraction (a - b, arithmetic)
, =	Multiplication (a * b, arithmetic)
/, /=	Division (a / b, arithmetic)
%, %=	Modulus (a % b, arithmetic)
&&	AND ((A > B) && (B > C), logical)
\|\|	OR ((A < B) \|\| (A < C), logical)
!	NEGATION (!(A == B), logical)
==	Equal (a == b, relational)
!=	Not equal (a != b, relational)
<, <=	Less than, Less than or equal (a <= b, relational)
>, >=	Greater than, Greater than or equal (a > b, relational)
&, &=	Bitwise AND
\|, \|=	Bitwise inclusive OR
^, ^=	Bitwise exclusive OR
<<, <<=	Shift bits left
>>, >>=	Shift bits right
~	Complement

Very popular operators are used to increment or decrement an operand.

j = i++

assigns to j the unchanged value of i and than adds 1 to i.

j = ++i

adds 1 to i and than assigns to j the incremented value of i.

You may use the decrement Operator -- in the same manner.

There exist more efficient statements for arithmetic and bitwise operators:

a = a + 15

equals

 a += 15
