Issues with adding a random numbers to an array

Question

I am trying to add random numbers to an empty array 20 numbers 0-99. When I run the code below it prints out 51 numbers and they are all 0.

Can someone please help me figure out what I am doing wrong here.

import java.util.Random;

public class SortedArray 
{

    int randomValues;
    int[] value;

    public SortedArray()
    {
    }


    public int getRandom()
            {
              Random random = new Random();
              for(int j=0; j<20; j++)
              {
                 randomValues = random.nextInt(100);
              }
              return randomValues;
            }

    public int getArray()
    {
        int result = 0;
        value = new int[randomValues];
        for(int item : value)
        {
            System.out.println("The array contains " + item);
        }
        return result;
    }

}

Here is my main method

public class ReturnSortedArray 
{
    public static void main(String[] args)
    {
        SortedArray newArray = new SortedArray();

        int random = newArray.getRandom();
        int array = newArray.getArray();
        System.out.println(array);
    }
}

In your method getArray

the code

value = new int[randomValues];

is simply creating a new empty int array of size ramdomValues.

As the default value of an int is 0, that is what you are getting

Also in your method getRandom you are setting the same value time and time again

for (...)
    randomValues = random.nextInt(100);

try

public int[] getRandomArr()
{
  int randomValues [] = new int [20];
  Random random = new Random();
  for(int j=0; j<20; j++)
  {
     randomValues[j] = random.nextInt(100);
  }
  return randomValues;
}
