I am tring to get this preogram to sort an array.

/*
*This program sorts integers from lowest to highest
*/

public class syntaxfive{

  public static void main(String[] args){

     int[] a = new int[20];

     //Initialize the array to random numbers between 0 and 99
     for (int i = 0; i < a.length; i++)
        a[i] = (int)(Math.random()*10);
     print(a);
     sort(a);
     print(a);
  }

  public static void sort(int[] a){
     int itemToInsert;
     boolean stillLooking;

     // On the kth pass, insert item k into its correct position
among
     // the first k entries in array.

     // On the kth pass, insert item k into its correct position
among
     // the first k entries in array.

     for (int k = 1; k < a.length; k--){
         // Walk backwards through list, looking for slot to insert a[k]
         int j = k - 1;
         itemToInsert = a[k];
        stillLooking = true;
        while ((k >= 0) || stillLooking )
            if (itemToInsert > a[j])
            {
                a[k + 1] = a[j];
                k++;
            }
            else
                stillLooking = false;
           // Upon leaving loop, j + 1 is the index
           // where itemToInsert  belongs
           a[k - 1] = itemToInsert;
     }
  }

  static public void print(int[] a){
     for (int i = 0; i < a.length; i++)
        System.out.print(a[i]);
    System.out.println("");

  }
}
// Adam W. Bachorski
// 1. Added { to void sort.
// 2. Changed else to if.
// 3. Added (int) before math.random to make it an integer.
// 4. Added print(a) to print().
// 6. Changed double itemTo Insert to int.
// 7. Changed a[i] = (int)(Math.random()*10); to produce an int from
1-9.
// 8. Added brakcets to the if statement.
