Pass arguments to another method in Java

I'm trying to figure out how to pass all needed arguements from an additonal method to the main method. The code I had doesn't seem to be working now that the method has multiple arrays. I really need this main method to be able to print any array from the public int M method. Can someone please fix my main method so that it prints the array properly? Please don't suggest better ideas as I need to follow this way for my class. No matter what I do I get an error that the arguements are invalid for main method. Please explain as much as possible. package Labs1;

import java.util.*;

public class Module1Labs {

public int[] M(int[] firstArray, int[] secondArray) {

int[] myArray = new int[n];

for (int i = 0; i < myArray.length; i++) {

myArray[i] = i;

}

return myArray;

}

public static void main(String[] args){

Module1Labs obj = new Module1Labs();

int[] myArray2 = obj.M(99);

StringBuilder sb = new StringBuilder();

for (int i = 0; i < myArray2.length; i++) {

sb.append(myArray2[i] + " ");

}

System.out.println(sb);

}

}
