赋值运算符
赋值运算符
下面是
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 | |
+ = | 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 | |
- = | 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 | |
* = |
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 | * * |
/ = | 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, |
(%)= | 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% |
« = | 左移位赋值运算符 | |
» = | 右移位赋值运算符 | |
&= | 按位与赋值运算符 | C& |
^ = | 按位异或赋值操作符 | |
| = | 按位或赋值操作符 |
简单示例程序演示了赋值运算符:
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 );
}
}
/**
c = a + b = 30
c += a = 40
c -= a = 30
c *= a = 300
c /= a = 1
c %= a = 5
c <<= 2 = 20
c >>= 2 = 5
c >>= 2 = 1
c &= a = 0
c ^= a = 10
c |= a = 10
