Passing an variable through classes on init

Question

i have a main class
this class starts up another class
so iv got 3 classes
class1
-load class2
class2
-load class3
class3
maxslots = 0
now that maxslots variable i want to set up from the VERY first class1
but i cant see how you pass it thought the classes so its loaded when each class is started up
class class1{
     private static      class2 class2x= null;
  public static void main(String[] args) throws IOException {
          class2x= new class2(7);
}ok so my class 2 now has 7
public class class2 implements Runnable {
        int maxSlots = 0;
        static class3 class3x= new class3(maxSlots);
     public class2(int maxSlotsx) {
          maxSlots = maxSlotsx
public class class3{
        int maxSlots = 0;
     public class3(int maxSlotsx) {
                maxSlots = maxSlotsx
          System.out.println("maxSlots"+maxSlots);
}now in class 2 i CANT place the set up class3 thing within class2 constructor because its runnable and only want it done ONCE
any idea how to pass var 7 down to my end class3
thanks :)
