In java please In this exercise, you will need to create a static method called findString in the MatchingString class that should iterate over String[] arr looking for the exact match of the String that is passed as a parameter.

Return the index of the array where the String is found; if it does not exist in the array, return -1.

For example, if the word “Karel” is passed in, your method would return 1.

Explanation:

The following code is written in Java. It is a static method that takes in a String parameter and loops through the String array called arr comparing each element in the array with the word parameter that was passed. If it finds a match the method returns the index of that word, otherwise it will return -1

  public static int findString(String word){

               int index = -1;

               for (int x = 0; x < arr.length; x++) {

                       if (word == arr[x]) {

                               index = x;

                               break;

                       }

               }

               return index;

       }
