Remove last separator from print statement

Question

Here\'s a method for sorting an integer array. How can I remove the last separator form the output?

public void Sort(int[] sort) {
        for (int a:sort) {
            


        

Answer 1

You may use a StringBuilder as follows:

    StringBuilder sb =new StringBuilder();
    int[] sort = {1,2,3,4,5,7,89,4,9,6,11,23,178,29};
    for(int i : sort) sb.append(i+", ");
    if(sb.length()>2)       sb.delete(sb.length()-2, sb.length());
    System.out.println(sb.toString());

EDIT: This is not the sorting algorythm. This is just an example of how you can present it without the last comma.
