Why do I get 0 in the outputs?

I am trying to generate 100 random numbers between 1 and 1000. Then, I need to find their average and which of them is their maximum. I get a wrong output. How do I fix this?

Thank you very much.

Code:

---

import java.util.Random;

public class DataSet
{
        private Random randomGenerator;
        private int randomInt;
        private int total;
        private double average;
        private int highestValue = 1;

        public void Dataset()
        {
                total = 0;

                for (int i = 1; i <= 100; i++)
                {
                        randomInt = randomGenerator.nextInt(1000);

                        total = total + randomInt;
                       

                        if(highestValue < randomInt)
                        {
                                highestValue = randomInt;
                        }
                }
       
        }


        public double getAverage()
        {
                average = total/100;
                return average;
        }

        public int getMaximim()
        {
                return highestValue;
        }
       
       
        public int getRandomInt()
        {
                return randomInt;
        }
}

Code:

---

public class DataSetTester
{
        public static void main(String[] args)
        {
                DataSet jean = new DataSet();
               
                System.out.println("The average of the generated numbers is: " + jean.getAverage());
                System.out.println("The highest number of the generated random numbers is: " + jean.getMaximim());
       
               
        }

}

Nothing seems to be wrong.
Could you please tell us what's wrong with the output?

EDIT:
After a closer read I've discovered the problem.

Hint: You do not have a constructor.

You mean so that I can input a number? I don't need to input a number. All I need is for the program to randomly generate the numbers when I run it. Or am I wrong?

Code:

---

//constructor
public DataSet() {}

//method
public void DataSet() {}

---

Code:

---

DataSet jean = new DataSet(); // new DataSet() creates a new object of your class and calls the constructor

jean.DataSet(); //calls the method inside the class DataSet
