2.7.2 赋值及其扩展赋值运算符
赋值及其扩展运算符
| 运算符 | 用法举例 | 等效的表达式 |
|---|---|---|
| += | a += b | a = a+b |
| -= | a -= b | a = a-b |
| *= | a *= b | a = a*b |
| /= | a /= b | a = a/b |
| %= | a%= b | a = a%b |
【示例2-21】 扩展运算符
int a=3;
int b=4;
a+=b;//相当于a=a+b;
System.out.println("a="+a+"\nb="+b);
a=3;
a*=b+3;//相当于a=a*(b+3)
System.out.println("a="+a+"\nb="+b);
