Variable Argument Method

The following class describes a method that can accept a variable argument instead of a fixed argument list. This can be handy where the developer is not sure of the number of arguments that can come in for processing.

public class VariableArgs {

   public static void main(String args[]) {
       System.out.println("Sum of 2 args - 5 & 10: " + sumVarArgs(5,10));
       System.out.println("Sum of 3 args - 5, 10 & 20: " + sumVarArgs(5,10,20));
    /* Method to accept variable arguments of type int. */
   private static int sumVarArgs(int... intArgs)
       int sum = 0;
      //Reading all arguments and summing them
       for (int value: intArgs)
           sum = sum + value;
      //Returning the summation of all the arguments. 
       return sum;
