Show 例子 5

以下程序是一个演示赋值运算符的简单示例。 将以下Java程序复制并粘贴到Test.java文件中。 编译并运行此程序 -

例子 (Example)

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 );
   }
}

这将产生以下结果 -

输出 (Output)

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
