How would I solve this?

Need to find any occurences of duplicates adjacent to each other

public class FindingDupes { /* * */ public static boolean FindingDupes(int[] arr) { //-----------Start below here. To do: approximate lines of code = 5 // Loop through the array arr, checking for duplicates // adjacent to each other. if duplicates occur, return true, else return false //Hint: in the for loop, make sure you use a loop condition something like // i < arr.length - 1 rather than i < arr.length Why?? //Hint 2: as soon as you find a duplicate you can immediately return true // Loop through array, checking for duplicates // next to each other. }
