Bubble sort

I thought it had attached my attempt, can't see how to atttach it now. I've copied it as: public static void sort(int[] array) { //write your code here int[] arr = new int[30]; int n = arr.length; int temp = 0; for(int i=0; i < n; i++){ for(int j=1; j < (n-i); j++){ if(arr[j-1] > arr[j]){ //swap elements temp = arr[j-1]; arr[j-1] = arr[j]; arr[j] = temp;

This code is sorting the values of "arr", which is only declared on the 3rd line. Because it is only declared all the elements in the array will be the default value of 0. This code would do nothing with the values in "array", which is the array that needs to be sorted. Get rid of that extra array and change the rest of the code to use "array".

//                               ↓ this array needs to be sorted
public static void sort(int[] array) {
   //write your code here
   int[] arr = new int[30]; // but only this array which is all 0's is sorted
   int n = arr.length;
   int temp = 0;
   for (int i = 0; i < n; i++) {
      for (int j = 1; j < (n - i); j++) {
         if (arr[j - 1] > arr[j]) {
            //swap elements
            temp = arr[j - 1];
            arr[j - 1] = arr[j];
            arr[j] = temp;
         }
      }
   }
}
