賦值運(yùn)算符

下面是Java語(yǔ)言支持的賦值運(yùn)算符：

實(shí)例

面的簡(jiǎn)單示例程序演示了賦值運(yùn)算符。復(fù)制并粘貼下面的Java程序并保存為Test.java文件，然后編譯并運(yùn)行這個(gè)程序：

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 >>= a = " + c );
     c &= a ;
     System.out.println("c &= 2  = " + c );
     c ^= a ;
     System.out.println("c ^= a   = " + c );
     c |= a ;
     System.out.println("c |= a   = " + c );
  }
} 

以上實(shí)例編譯運(yùn)行結(jié)果如下：

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
