Printing number series with multiple threads

Problem: Write a code to print numbers 1 to 10 with using two threads such that one thread prints 1, 3, 5, 7, 9 and other thread prints 2, 4, 6, 8, 10


Solution:
Below is the code I wrote first but do not believe it to be an elegant solution, I plan to write a more elegant solution later but let's see when it happens.
With this solution, I ran into an issue when I used Integer class instead of MyInteger, could you spot the issue?

 public class AlternatePrint implements Runnable {  
   int id;  
   MyInteger number;  
   // Integer number;  
   AlternatePrint(int id, MyInteger number) {  
     this.id = id;  
     this.number = number;  
   }  
   public void run() {  
     int last = id;  
     while (number.getValue() <= 10) {  
       synchronized (number) {  
         if (last != number.getValue()) {  
           System.out.println("Thread: " + id + " printing: "  
               + number.getValue());  
           number.setValue(number.getValue() + 1);  
           last = number.getValue();  
           // number++;  
           // last = number;  
         }  
         try {  
           number.wait(100);  
         } catch (InterruptedException e) {  
           // TODO Auto-generated catch block  
           e.printStackTrace();  
         }  
       }  
     }  
     System.out.println("Thread: " + id + " exiting!!!");  
   }  
   public static void main(String[] args) {  
     AlternatePrint a, b;  
     MyInteger o = new MyInteger(1);  
     a = new AlternatePrint(1, o);  
     b = new AlternatePrint(2, o);  
     new Thread(a).start();  
     new Thread(b).start();  
     System.out.println("Main Thread exiting!!!");  
   }  
 }  
 class MyInteger {  
   private int value;  
   MyInteger(int value) {  
     this.value = value;  
   }  
   public int getValue() {  
     return value;  
   }  
   public void setValue(int value) {  
     this.value = value;  
   }  
 }
