public class Adapters1
  {
  public static void main( String[] args )
    {
    int ints[] = { 3, -1, 2, -3, 4 };
    IntArray intArray = new IntArray( ints );
    System.out.println( "Unsorted native int array = " + intArray );

Adapters1 Example Output
Unsorted native int array = int[]( 3, -1, 2, -3, 4 )
Sorted = int[]( -3, -1, 2, 3, 4 )
Randomized = int[]( -3, 4, 2, 3, -1 )

public class Adapters2
  {
  public static void main( String[] args )
    {
    Vector vector = new Vector();
    vector.addElement( new Integer( 3 ) );
    vector.addElement( new Integer( -1 ) );

    vector.addElement( new Integer( -3 ) );
    vector.addElement( new Integer( 4 ) );

    VectorArray vectorArray = new VectorArray( vector );
    System.out.println( "Unsorted JDK Vector = " + vectorArray );

    Sorting.sort( vectorArray );
    System.out.println( "Sorted = " + vectorArray );

    Shuffling.randomShuffle( vectorArray );
    System.out.println( "Randomized = " + vectorArray );
   
    System.out.println( "JDK vector = " + vector );
    }
  }


Adapters2 Example Output
Unsorted JDK Vector = [3, -1, 2, -3, 4]
Sorted = [-3, -1, 2, 3, 4]
Randomized = [-1, -3, 2, 4, 3]
JDK vector = [-1, -3, 2, 4, 3]
