下面是Java语言支持的赋值运算符：

    操作符 描述 例子
    = 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，C 与 A 同类型时等价于 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 
    1. public class Test {
    2.     public static void main(String[] args) {
    3.         int a = 10;
    4.         int b = 20;
    5.         int c = 0;
    6.         c = a + b;
    7.         System.out.println("c = a + b = " + c );
    8.         c += a ;
    9.         System.out.println("c += a  = " + c );
    10.         c -= a ;
    11.         System.out.println("c -= a = " + c );
    12.         c *= a ;
    13.         System.out.println("c *= a = " + c );
    14.         a = 10;
    15.         c = 15;
    16.         c /= a ;
    17.         System.out.println("c /= a = " + c );
    18.         a = 10;
    19.         c = 15;
    20.         c %= a ;
    21.         System.out.println("c %= a  = " + c );
    22.         c <<= 2 ;
    23.         System.out.println("c <<= 2 = " + c );
    24.         c >>= 2 ;
    25.         System.out.println("c >>= 2 = " + c );
    26.         c >>= 2 ;
    27.         System.out.println("c >>= 2 = " + c );
    28.         c &= a ;
    29.         System.out.println("c &= a  = " + c );
    30.         c ^= a ;
    31.         System.out.println("c ^= a   = " + c );
    32.         c |= a ;
    33.         System.out.println("c |= a   = " + c );
    34.     }
    35. }
    37. 输出结果：
    38. c = a + b = 30
    39. c += a  = 40
    40. c -= a = 30
    41. c *= a = 300
    42. c /= a = 1
    43. c %= a  = 5
    44. c <<= 2 = 20
    45. c >>= 2 = 5
    46. c >>= 2 = 1
    47. c &= a  = 0
    48. c ^= a   = 10
    49. c |= a   = 10
