Groovy Programming Examples

Groovy Switch Statement

groovy

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; 
      }
   }
}

Groovy Nested If Statement

groovy

class Example { 
   static void main(String[] args) { 
      // Initializing a local variable 
      int a = 12 
		
      //Check for the boolean condition 
      if (a>100) {
         //If the condition is true print the following statement 
         println("The value is less than 100"); 
      } else 
         // Check if the value of a is greater than 5 
			
      if (a>5) { 
         //If the condition is true print the following statement 
         println("The value is greater than 5 and greater than 100"); 
      } else { 
         //If the condition is false print the following statement 
         println("The value of a is less than 5"); 
      }  
   } 
}

Groovy If/Else Statement

groovy

class Example { 
   static void main(String[] args) { 
      // Initializing a local variable 
      int a = 2
		
      //Check for the boolean condition 
      if (a<100) { 
         //If the condition is true print the following statement 
         println("The value is less than 100"); 
      } else { 
         //If the condition is false print the following statement 
         println("The value is greater than 100"); 
      } 
   } 
}

Groovy If Statement

groovy

class Example { 
   static void main(String[] args) { 
      // Initializing a local variable 
      int a = 2 
		
      //Check for the boolean condition 
      if (a<100) { 
         //If the condition is true print the following statement 
         println("The value is less than 100"); 
      } 
   } 
}

Groovy Continue Statement

groovy

class Example {
   static void main(String[] args) {
      int[] array = [0,1,2,3];
		
      for(int i in array) {
         println(i);
         if(i == 2)
         continue;
      }
   }
}

Groovy Break Statement

groovy

class Example {
   static void main(String[] args) {
      int[] array = [0,1,2,3];
		
      for(int i in array) {
         println(i);
         if(i == 2)
         break;
      }
   } 
}

for-in statement can also be used to loop through Map’s

groovy

class Example {
   static void main(String[] args) {
      def employee = ["Ken" : 21, "John" : 25, "Sally" : 22];
		
      for(emp in employee) {
         println(emp);
      }
   }
}

for-in statement used to loop through ranges

groovy

class Example {
   static void main(String[] args) {
	
      for(int i in 1..5) {
         println(i);
      }
		
   } 
}

for-in statement

groovy

class Example { 
   static void main(String[] args) { 
      int[] array = [0,1,2,3]; 
		
      for(int i in array) { 
         println(i); 
      } 
   } 
}

Groovy For Statement

groovy

class Example { 
   static void main(String[] args) {
	
      for(int i = 0;i<5;i++) {
	     println(i);
      }
		
   }
}
