Java Code to Avoid Dead Lock ?

There would not be any deadlock because both methods are accessing lock on Integer and String class literal in same order. So, if thread A acquires lock on Integer object , thread B will not proceed until thread A releases Integer lock, same way thread A will not be  blocked even if thread B holds String lock because now thread B will not expect thread A to release Integer lock to proceed further.

public class DeadLockAvoid {

public void method1(){

synchronized(String.class){

System.out.println("Aquired lock on String.class object");

synchronized(Integer.class){

System.out.println("Aquired lock on Integer.class object");

}

}

}

public void method2(){

synchronized(String.class){

System.out.println("Aquired lock on String.class object");

synchronized(Integer.class){

System.out.println("Aquired lock on Integer.class object");

}

}

}

}
