Groovy 關(guān)系運(yùn)算符

關(guān)系運(yùn)算符允許對(duì)象的比較。以下是Groovy中可用的關(guān)系運(yùn)算符 -

以下代碼段顯示了如何使用各種運(yùn)算符。

class Example { 
   static void main(String[] args) { 
      def x = 5;
      def y = 10;
      def z = 8;
		
      if(x == y) { 
         println("x is equal to y"); 
      } else 
         println("x is not equal to y"); 
			
      if(z != y) { 
         println("z is not equal to y"); 
      } else 
         println("z is equal to y"); 
				
      if(z != y) { 
         println("z is not equal to y"); 
      } else 
         println("z is equal to y"); 
					
      if(z<y) { 
         println("z is less than y"); 
      } else 
         println("z is greater than y"); 
						
      if(x<=y) { 
         println("x is less than y"); 
      } else 
         println("x is greater than y"); 
			
      if(x>y) { 
         println("x is greater than y"); 
      } else 
         println("x is less than y"); 
			
      if(x>=y) { 
         println("x is greater or equal to y"); 
      } else 
         println("x is less than y"); 
   } 
} 

當(dāng)我們運(yùn)行上面的程序，我們將得到以下結(jié)果。可以看出，結(jié)果如從上面所示的操作符的描述所預(yù)期的。

x is not equal to y 
z is not equal to y 
z is not equal to y 
z is less than y
x is less than y 
x is less than y 
x is less than y
