Why do I get 0 in the outputs?

[jean28]

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.

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;
	}
}

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?

[JBelg]

//constructor
public DataSet() {}

//method
public void DataSet() {}

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
