Core Java: Compound Assignment Operators

Besides the usual simple assignment operator (=) described earlier, Java also provides the so-called compound assignment operators as listed:

 

Operation	Description	Usage	Example
=	Assignment Assign the value of the LHS to the variable at the RHS	var = expr	x = 5;
+=	Compound addition and assignment	var += expr same as var = var + expr	x += 5; same as x = x + 5
-=	Compound subtraction and assignment	var -= expr same as var = var - expr	x -= 5; same as x = x - 5
*=	Compound multiplication and assignment	var *= expr same as var = var * expr	x *= 5; same as x = x * 5
/=	Compound division and assignment	var /= expr same as var = var / expr	x /= 5; same as x = x / 5
%=	Compound remainder (modulus) and assignment	var %= expr same as var = var % expr	x %= 5; same as x = x % 5
