Groovy Switch Statement

class Example { 
   static void main(String[] args) { 
      //initializing a local variable 
      int a = 2
		
      //Evaluating the expression value 
      switch(a) {            
         //There is case statement defined for 4 cases 
         // Each case statement section has a break condition to exit the loop 
			
         case 1: 
            println("The value of a is One"); 
            break; 
         case 2: 
            println("The value of a is Two"); 
            break; 
         case 3: 
            println("The value of a is Three"); 
            break; 
         case 4: 
            println("The value of a is Four"); 
            break; 
         default: 
            println("The value is unknown"); 
            break; 
      }
   }
