lottery GUI program

[jib123]

Ive created an operating GUI lottery program which should generate 6 random numbers between 0-49. The only problem i have is that it doesnt do so. I have only been given this program to create 3 days ago and have to hand it in next week.

At the moment the program keeps generating the numbers 1,2,3,4,5,6 whenever i press on the button to generate. I know this may be a fairly easy fix to some but i have looked and relooked at my code and cant see whats wrong.

import java.util.*;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener; 

public class lotteryGenerator implements ActionListener

{       
        private JFrame frame = new JFrame("Lottery Generator Program");
        private JPanel panel = new JPanel(); 
        private JButton generateLottoNums = new JButton("Generate Numbers");
        private String lottoNums = "";
        private JTextField lotteryText = new JTextField(20);
        ImageIcon Lottery = new ImageIcon("Lottery.png");
        private JLabel label = new JLabel(Lottery);
             
        
        public static void main (String[] args)
        {
            lotteryGenerator gui = new lotteryGenerator();
        }
        
        public void lotteryGenerator()
        {
           //Defining the Window
            frame.add(panel);
            frame.setSize(500, 300);
            frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
            frame.setVisible(true);
            generateLottoNums.addActionListener(this);
           
            //Adding the button, label and image to the panel
            panel.add(label);
            panel.add(generateLottoNums);
            panel.add(lotteryText);
        }
        
        int[] lotteryGenerator = new int[50];
        int i = 0;
        Random rgen = new Random();
        
        //Creating an Array of 50 integers
        public void createNumbers()  
        {
            //Creating an Array of 50 Integers            
            for (i=0; i < lotteryGenerator.length; i++) 
            {   
                lotteryGenerator[i] = i + 1;
            }
        }
        
        public void shuffleNumbers()
        {
            // Shuffling the numbers in the array
            for (int i=0; i < lotteryGenerator.length; i++) 
            {
                int randomPosition = rgen.nextInt(lotteryGenerator.length);
                int temp = lotteryGenerator[i];
                lotteryGenerator[i] = lotteryGenerator[randomPosition];
                lotteryGenerator[randomPosition] = temp;
            }           
        }     
    
        //Sorting the numbers in the array
        public void sortNumbers()
        {
           for(int i=0; i < lotteryGenerator.length-1; i++) 
            {
               for(int j=0; j < lotteryGenerator.length-1-i; j++) 
                {
                    if(lotteryGenerator[j] > lotteryGenerator[j+1]) 
                    {
                       int temp = lotteryGenerator[j];
                       lotteryGenerator[j] = lotteryGenerator[j+1];
                       lotteryGenerator[j+1] = temp;
                    }
                }
            }        
                       
        }
    
       // Printing the numbers out
       public void showNums()
       {
          for (int i = 0; i < 6; i++)
          {
               lottoNums += " " + lotteryGenerator[i] + " ";
          }
          lotteryText.setText(lottoNums);
       }
        
        public void actionPerformed(ActionEvent e)
        {
            createNumbers();
            shuffleNumbers();
            sortNumbers();
            showNums();
        }
}

            createNumbers();
            shuffleNumbers();
            sortNumbers();
            showNums();

Maybe because you sort them every time after you shuffle them?
