# Compound Assignment Operator

Compound assignment operator(+=,-=,*=,/=,%=,&=,|=,^=,<<=,>>=,>>>=)are a combination of the assignment operator and an another operator such as an arithmetic operator. So they are also known as Shorthand assignment operators.

Syntax:

Variable operator variable or constant

The following Table shows the compound assignment operators and their usage....

Operator                   Expression(shorthand)                   Meaning

+=                             vall+=increasee;                          vall=vall+increasee;

-=                             firstt-=25;                                     firstt=firstt-25;

/=                             firstt/=sec;                                   firstt=firstt/sec;

*=                           costt*=qtty+1;                              costt=costt*(qtty+1);

%=                         FIRR%=SECC;                               FIRR=FIRR%SECC;

&=                        firstt&=seec;                                    firstt=firstt&seec;

|=                           firstt|=seec;                                    firstt=firstt|seec;

^=                           firstt^=seec;                                  firstt=firstt^seec;

<<=                       cpricee<<=spricee;                       cpricee=cpricee<<spricee;

>>=                       firstt>>=seec;                                firstt=firstt>>seec;

>>>=                     biib>>>=niib;                                biib=biib>>>niib;

## Exampleâ€¦..

class CompoundAssignment

{

public static void main(String aa[])

{

int a,b,c;

a=1;

b=2;

c=3;

a+=5;

b*=4;

c+=a*b;

c%=6;

System.out.println("a="+a);

System.out.println("b="+b);

System.out.println("c="+c);

System.out.println("c%="+c);

}

}
