Letters and Symbols are printed when trying to store random numbers into an array [duplicate]

• What's the simplest way to print a Java array? 25 answers

I've written this program to find 20 random numbers and store them into an array. Which then calls onto another class to print the array.( It was required to use two classes). Both of my programs compile fine however the output I recieve is

[I@12f55e8

instead of a list of numbers that were stored into the array. Can anyone tell me why this might be. Here is my program

Here is my displayArray method. It is just a method to print the array

**
 * Displays array 
 * pre: array made
 * post: array printed 
 * 
 */

 public class DisplayArrayAP
 {
 //



public static int[] toString (int[] array) 
{
   return(array);
}
}

Here is my main program

import java.util.*;
import java.io.*;

import java.util.Random;

public class TesterRandomAP
{
public static void main(String[] args) {

    //creating a new display object with an array with 20 indexes


    int[] array = new int[20];

   DisplayArrayAP result = new DisplayArrayAP(); 
    //creating a random object 
    Random rand = new Random();

    //loop to access array
    for(int index = 0; index < array.length; index++) {

        //stores random number into array
        array[index] = rand.nextInt(30)+1;


    }




  System.out.println(result.toString(array));
  }
}
