java赋值运算符

=	简单的赋值运算符，将右操作数的值赋给左侧操作数	C = A + B将把A + B得到的值赋给C
+ =	加和赋值操作符，它把左操作数和右操作数相加赋值给左操作数	C + = A等价于C = C + A
- =	减和赋值操作符，它把左操作数和右操作数相减赋值给左操作数	C - = A等价于C = C -  A
* =	乘和赋值操作符，它把左操作数和右操作数相乘赋值给左操作数	C * = A等价于C = C * A
/ =	除和赋值操作符，它把左操作数和右操作数相除赋值给左操作数	C / = A等价于C = C / A
（％）=	取模和赋值操作符，它把左操作数和右操作数取模后赋值给左操作数	C％= A等价于C = C％A
<< =	左移位赋值运算符	C << = 2等价于C = C << 2
>> =	右移位赋值运算符	C >> = 2等价于C = C >> 2
＆=	按位与赋值运算符	C＆= 2等价于C = C＆2
^ =	按位异或赋值操作符	C ^ = 2等价于C = C ^ 2
| =	按位或赋值操作符	C | = 2等价于C = C | 2

实例：

package pkg3;
public class Test {
public static void main(String[] args) {
int a = 10;
int b = 20;
int c = 0;
c = a + b;
System.out.println("c = a + b = " + c );
c += a ;
System.out.println("c += a = " + c );
c -= a ;
System.out.println("c -= a = " + c );
c *= a ;
System.out.println("c *= a = " + c );
a = 10;
c = 15;
c /= a ;
System.out.println("c /= a = " + c );
a = 10;
c = 15;
c %= a ;
System.out.println("c %= a = " + c );
c <<= 2 ;
System.out.println("c <<= 2 = " + c );
c >>= 2 ;
System.out.println("c >>= 2 = " + c );
c >>= 2 ;
System.out.println("c >>= 2 = " + c );
c &= a ;
System.out.println("c &= a = " + c );
c ^= a ;
System.out.println("c ^= a = " + c );
c |= a ;
System.out.println("c |= a = " + c );
}
}
