linking code together

The numbers that are generated through this code needs to go into an arraylist in the same order. I have to be able to have each number to be associated to an audio file which are in a hashmap linked to a checkbox. I have the code for the hashmap to checkboxs if needed


import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.util.*;
import java.lang.*;



public class TestIt {
    public static void main(String[] args) {
        printRows();
   }

// Generate numbers fir training

static void printRows() {
    final int INDEX_LIMIT = 8;
          final int BATCH_LENGTH_LIMIT = 8;
    final int BATCH_SIZE = 4;
    final int NUM_BATCH_GROUPS = 4;
    int batchLength = 4;
          // Disallow duplicates by using a Set
    Set numbers = new HashSet();
    for (int batchGroup = 0; batchGroup < NUM_BATCH_GROUPS; batchGroup++) {
               // Add numbers if more needed
      while (numbers.size() < batchLength && batchLength < BATCH_LENGTH_LIMIT) {
        numbers.add(new Integer((int)(Math.random()  * INDEX_LIMIT) + 1));
      }
      for (int batchSize = 0; batchSize < BATCH_SIZE; batchSize++) {
        java.util.List list = new ArrayList(numbers);
                    // Shuffle and print
        Collections.shuffle(list);
        System.out.println(list);
      }
      batchLength++;
      System.out.println();
    }
  }  
}


// Checkboxs to audio files Audio files to Checkboxs

public class CheckBoxesToAudioFiles {
     Map checkToAudio;

     public CheckBoxesToAudioFiles {
          checkToAudio = new HashMap();
     }
     
     public void mapCheckboxToAudioFile(JCheckbox cb, AudioFile af) {
          checkToAudio.put(cb, af);
     }
     
     public AudioFile getAudioFileForCheckbox(JCheckbox cb) {
          (AudioFile)return checkToAudio.get(cb);
     }
     
}
