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

Couple of options:

public void Sort(int[] sort) {
  for (int i = 0; i < sort.length; i++) {
     System.out.print(sort[i]);
     if (i < sort.length - 1) {
       // not the last element. Add separator
       System.out.print(" ,");  
     }
  }
}

Another way:

public void Sort(int[] sort) {
  String output = Arrays.toString(sort);
  System.out.println(Arrays.toString(output).substring(1, output.length-1));
}
