Question

PLease! Need help in java!!!!!!
I'm trying to put int x[]= {3, 6, 4, 1 } into an ArrayList,sort in ascending order and return it.
public ArrayList<Integer> lookOut( int x[]) {
      
       ArrayList<Integer> list = new ArrayList<Integer>();
       for(int i =0; i < x.length; i++){
           list.add(x[i]);
       Collections.sort(list);
       }      
       return list;
   }

My test case:
   public void lookOut() {
       int x[] = { 3, 6, 4, 1 };
      
       AscendOrder ascendOrder = new AscendOrder();

       ArrayList<Integer> list = ascendOrder.lookOut( x );
       for ( int i = 0 ; i < x.length ; i++ ) {
           assertEquals( new Integer(i), list.get(i) );
       }
   }

Answer 1

public ArrayList<Integer> lookOut( int x[]) {
  ArrayList<Integer> list = new ArrayList<Integer>();
  for(int i =0; i < x.length; i++){
    list.add(x[i]);
  }
  Collections.sort(list);
  return list;
}

=================================

public void lookOut() {
      int x[] = {3, 6, 4, 1};
      int y[] = {1, 3, 4, 6};
      AscendOrder ascendOrder = new AscendOrder();
      ArrayList<Integer> list = ascendOrder.lookOut(x);
      for (int i = 0; i < x.length; i++) {
        assertEquals(y[i], list.get(i));
      }
}
