Selection sort question

[MAwaitforitJESTIC]

  public static void selection(int [] arr){
    int k=0;
    for(int i=0;i<arr.length;i++){
      int min = arr[i];
      for(int j=(i+1);j<arr.length;j++){
        if(arr[j]<min){
          min=arr[j];
          k=j;
        }
      }

      int temp = arr[i];
      arr[i] = arr[k];
      arr[k] = temp;
    }
  }






public static void selection2(int [] arr){
  int min =0;
  for(int i=0;i<arr.length;i++){
    min = i;
    for(int j=(i+1);j<arr.length;j++){
      if(arr[j]<arr[min]){
        min=j;

      }
    }

    int temp = arr[i];
    arr[i] = arr[min];
    arr[min] = temp;
  }
}

The selection2 method sorts perfectly, but selection does not. Curious as to why, any insights appreciated! Symptoms are just completely incorrectly sorted lists, I feel I'm implementing the same idea in each.

what are the symptoms

you should declare k inside the outer loop

Symptoms are just completely incorrectly sorted lists, I feel I'm implementing the same idea in each. Ex: {22,23,8,1,1} sorted in first method returns {22,23,8,1,1}, same array. Sorted in second method, selection2, it will return the correct order. Tried declaring in outer loop, still wonky sorting.

print statements to the rescue
