Returning Array from Methods

7.5 Returning Array from Methods

A reference to an array can be returned from a method, look at the following program :

/**
 * This program demonstrates how a reference to an
 * array can be returned from a method.
 */
public class ReturnArray
{
   public static void main(String[] args)
   {
      final int NUMBER = 4;    // number of the elements

      // Create an array variable.
      int[] values;

      // Values reference the array returned
      // from the randomArray method.
      values = randomArray(NUMBER);

      // Display the values in the array.
      for (int i = 0; i < values.length; i++)
      {
         System.out.print(values[i] + " ");
      }
   }

   /**
    * The randomArray method accept number as argument and
    * returns a reference to an array of integers.
    */
   public static int[] randomArray(int n)
   {
      int[] list = new int[n];

      for (int i = 0; i < list.length; i++)
      {
         list[i] = (int) (Math.random() * 10);
      }

      return list;
   }
}

Output :
