Relational

Java has six relational operators that compare two numbers and return a boolean value.

The relational operators are `<`, `>`, `<=`, `>=`, `==`, and `!=`.

Operator	Example	Meaning of Operator	Value of the Boolean
<	x < y	Less than	True if x is less than y, false otherwise
>	x > y	Greater than	True if x is greater than y, false otherwise
<=	x <= y	Less than or equal to	True if x is greater than or equal to y, false otherwise
>=	x >= y	Greater than or equal to	True if x is greater than or equal to y, false otherwise
==	x == y	Equal	True if contents of x equal those of y, false otherwise
!=	x != y	Not equal	True if x is not equal to y, false otherwise

Assignment

Operator	Example	Meaning of Operator
=	x = y	Place the contents of y in x and leave the contents of y unchanged
+=	x += y	x = x + y
-=	x -= y	x = x - y
*=	x *= y	x = x * y
/=	x /= y	x = x/y
%=	x % y	x = x % y

Operator	Example	Meaning of Operator	Value of the Boolean
&&	a && b	Logical and	True if both a and b are true, false otherwise
\|\|	a \|\| b	Logical or	True if either a or b is true, false if both are false

Math

Operator	Example	Meaning of Operator	Comments
+	a + b	Addition	Add a and b
-	a - b	Subtraction	Subtract b from a
*	a * b	Multiplication	Multiply a and b
/	a / b^{see notes}	Division	Divide b into a
%	a % b^{see notes}	Modulus	Remainder from dividing b into a

Notes:

If a and b are both integers, the division operator will return the quotient

The modulus operator is only applicable to integer division - it will return the remainder
