Question

4. Please name your driver program XXX_P04 where XXX are your initials. Given the array inputArray (doubles), write a method called swap which will swap any two contiguous (next to each other) elements. Swap will be passed two parameters, the index of the first element to be swapped and the array name. Write another method printArray that will print the array 5 elements to a line. PrintArray will be passed one parameter the array name. See the videos for help with this. The array elements are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

Executable Code:

public class XXX_P04
{
   //Main Program
   public static void main(String[] args)
   {
       //Declaring required array
       double[] inputArray = {1,2,3,4,5,6,7,8,9,10};
       printArray(inputArray);
       //Calling the method
       swap(5, inputArray);
       System.out.println();
       printArray(inputArray);
   }

   //Method to swap
   public static void swap(int k, double [] input) {
       //Swapping the elements
       double temp = input[k];
       input[k] = input[k+1];
       input[k+1] = temp;
   }

   //Method to print the result
   public static void printArray(double[] input) {
       for(int i = 0; i < input.length; ++i) {
           System.out.print(input[i] + " ");
           //Printing the result
           if((i+1) % 5 == 0) {
               System.out.println();
           }
       }
   }
}
