Now, 1 - input new string and add it to the existing ArrayList, 2-input a string, then check if the current string exists in the ArrayList, 3- Sort the existing ArrayList alphabetically, 4- input a string, and check if it exists, remove it from the ArrayList, 5-input an index, then change the content of that index with "Antalya" 6- finally, reverse the ArrayList order. For each step above, print the array list before and after the modification, and each step must be defined in a separate method, named as following: printArrayList, addToArrayList, checkExistance, sortArrayList, replaceArrayList, reverseArraylist
