I REALLY need help with this! (not too hard) (but hard to explain) (long)

Question

I know that this isn't hard, but I just can't figure it out.
I am trying to create artificial cellular life, but the cells will be able to go through sexual reproduction.
The DNA for the cells is a 500 index boolean array. One array for Dominant genes, and another one for Rececive genes.
The DNA is generated randomly.
The division (to make a sperm cell) works like this -
1. I get a random number with the Math.random() function, and I use the Math.round() function to round it to either a 1, or a 0.
2. The boolean arrays are converted to integer arrays (true = 1, false = 0).
3. If the random number is a 1, then (in a for loop) the current index value of the dominant array is changed to a 3. If the random numnber is equal to a 0, then the current index value of the rececive array is changed to a 3.
I started working on a new class, to combine the sperm cell with another sperm cell (call it an egg cell, whatever, doesn't matter) in order to create a new complete cell.
I realized that I have no idea how I can reuse my classes, and make NEW cells, without overwriting my old cells.
All of the final information that the classes produce is passed through TestMain.class (which puts it into other variables, and sends it to the appropriate class).
So, I need to be able to run the process for creating a cell, then creating a sperm cell out of it, twice.
I can, of course, just copy and paste this action, but seeing as how I want to have unlimited amounts of cells in action, this would not be practical.
Here are my classes, sorry that they are not commented, but I explained what they do above, and I will write what they do overall.
Genes.java - Creates the random DNA (and is essentially the cell)
public class Genes {
public boolean[] domgenes = new boolean[501];
public boolean[] recgenes = new boolean[501];
    public void randgenes()
System.out.println ("Dominant Genome: ");
System.out.println ("");
int domcount = 0;
        for(int i=0; i<500; i++) {
            double tempgene = (Math.round((Math.random())));
            int tempdomgene = (int)(tempgene);
              if(tempdomgene == 1) {
              domgenes[i] = true;
            System.out.print(1);
              else {
              domgenes[i] = false;
            System.out.print(0);
          for (int x = 0; x<500; x++) {
            if (domcount == 0) {
            System.out.println("");
            System.out.println("");
            System.out.println ("Rececive Genome: ");
            System.out.println("");
            domcount = 1;
            double tempgene = (Math.round((Math.random())));
            int temprecgene = (int)(tempgene);
              if(temprecgene == 1) {
              recgenes[x] = true;
              System.out.print(1);
              else {
              recgenes[x] = false;
              System.out.print(0);
    public boolean[] getdomGenes()
        System.out.println("");
        return domgenes; //returns the dominant genome
    public boolean[] getrecGenes()
        return recgenes; //returns the rececive geneome
    }DivideGenes.java - This creates the sperm cell out of the information that TestMain.java sent it (which is the information that Genes.java sent to it).
public class DivideGenes
    int badcopy =0;
    boolean[] domgenes;
    boolean[] recgenes;
    int[] tempdomgenes = new int[501];
    int[] temprecgenes = new int[501];
    int tempgene;
    int geneholder;
    public DivideGenes(boolean[] domgenes, boolean[] recgenes)
        this.domgenes = domgenes;
        this.recgenes = recgenes;
   public int randommath() { //finds a random number
            double tempgene2 = Math.random();
            tempgene2 = tempgene2*500;
            tempgene = (int)tempgene2;
      return tempgene;
    public void randdivide() //main process
for (int i = 0; i < 500; i++) {
if (domgenes[i] == true) {
tempdomgenes[i] = 1;
else {
tempdomgenes[i] = 0;
if (recgenes[i] == true) {
temprecgenes[i] = 1;
else {
temprecgenes[i] = 0;
        for (int i = 0; i < 500; i++) { //creates the sperm cell
if (binmath() == 1) {
tempdomgenes[i] = 3;
else {
temprecgenes[i] = 3;
  public int[] getNewDomGenes()
  return tempdomgenes;
  public int[] getNewRecGenes()
  return temprecgenes;
    public int binmath() {
    double tempbingene = (Math.round((Math.random())));
           int bingene = (int)(tempbingene);
            return bingene;
  }TestMain.java - This is the class that all of the result information is passed through, and is the regulator class (this is the class with the 'main' block). I used the names of the objects randomly, they do not represent anything (like cell2 does not represent the second cell), they are just names.
public class TestMain
    public static void main(String[] args)
        Genes cell = new Genes();
        cell.randgenes();
        boolean[] theDominantGenes = cell.getdomGenes();
        boolean[] theRececiveGenes = cell.getrecGenes();
        DivideGenes cell2 = new DivideGenes(theDominantGenes, theRececiveGenes);
        cell2.randdivide();
       int[] theTempDominantGenes = cell2.getNewDomGenes();
       int[] theTempRececiveGenes = cell2.getNewRecGenes();
     CreateNewCell cell3 = new CreateNewCell (theTempDominantGenes,theTempRececiveGenes);
  cell3.CompileCell();
  }CreateNewCells.java - This is going to combine two sperm cells in order to make one new cell. It doesn't have anything in it so far, just some System.out.println stuff I made to show my friends.
public class CreateNewCell {
int[] tempdomgenes;
int[] temprecgenes;
public CreateNewCell(int[] tempdomgenes, int[] temprecgenes)
        this.tempdomgenes = tempdomgenes;
        this.temprecgenes = temprecgenes;
public void CompileCell() {
System.out.println("");
System.out.println("Sperm Division Started");
System.out.println("------------------------------------------");
System.out.println("");
System.out.println ("Dominant Genome after random gene elimination");
System.out.println("");
for (int i = 0; i < 500; i++) {
System.out.print(tempdomgenes);
System.out.println("");
System.out.println("");
System.out.println ("Rececive Genome after random gene elimination");
System.out.println("");
for (int i = 0; i < 500; i++) {
System.out.print(temprecgenes[i]);
Thank you very much if you choose to help me out.

Answer 1

As I said before, your code is not object.
When you write
DivideGenes cell2 = new DivideGenes(theDominantGenes, theRececiveGenes);it means than from 2 Genes, you are creating a new object which is DivideGenes. I assume that what you want is to create a cell from an other cell and its mate.
So it should be:
public class Cell {
  //put here your gene class attributes and methods
  public Cell divideCell(Cell mate) {
     Cell child = new Cell();
     //put here your divide code
     return child;
}Otherwise I can't understand your code.
What kind of object is a createcellGene?? It must be a method of Cell !!
