Pbroblems with Synchronized methods --- please help

Question

** One Thread calls a synchronized method using an object (obj1) of a Class (Class name - meth_class) and occupies the monitor of that particular object (obj1). Then no other Thread can call that particular synchronized method or any other synchronized method of the object (obj1) of a Class (Class name - meth_class). **
          IF THE ABOVE DEFINITION IS TRUE PLEASE HELP ME OUT WITH THE FOLLOWING:
Please go through the code below:-
class meth_class
          volatile boolean valueset=false;
          int var;
          synchronized int get()
                    if (!valueset)
                              try
                                        wait();
                              catch (InterruptedException e)
                                        System.out.println("Consumer interrupted");
                    System.out.println("Get - " + var);
                    valueset=false;
                    notify();
                    return var;
          synchronized void put(int x)
                    if (valueset)
                              try
                                        wait();
                              catch (InterruptedException e)
                                        System.out.println("Producer interrupted");
                    this.var=x;
                    System.out.println("Put - " + var);
                    valueset=true;
                    notify();
class producer implements Runnable
          meth_class obj;
          Thread thrd;
          producer(meth_class x)
                    obj=x;
                    thrd=new Thread(this, "Producer");
                    thrd.start();
          public void run()
                    int var=0;
                    while(true)
                              obj.put(var++);
class consumer implements Runnable
          meth_class obj;
          Thread thrd;
          consumer(meth_class x)
                    obj=x;
                    thrd=new Thread(this, "Consumer");
                    thrd.start();
          public void run()
                    while(true)
                              obj.get();
class main_thrd
          public static void main(String args[])
                    meth_class obj=new meth_class();
                    new producer(obj);
                    new consumer(obj);
                    System.out.println("Press Control-C to stop");
My Questions are:
1.     class main_thrd creates two objects as ?new producer(obj)? and ?new consumer(obj)?. Now both these objects creates 2 threads and try to call two different Synchronized methods of same CLASS ? ?meth_class? through a single object by the name of ?obj? created in class main_thrd. Now as ?new producer(obj)? object is created first in the class main_thrd, the Thread created by it enters the monitor of object (obj) and locks it. Then as per the rule the Thread created by ?new consumer(obj)? object never gets to occupy the monitor of the object (obj) because Producer is in an infinite loop. BUT THEN WHY WE HAVE ? GET - ** ? VALUES PRINTED IN THE OUTPUT.
Please any one help me out,
(THANKS FOR ALL YOUR HELP)

Answer 1

Now as ?new producer(obj)? object is called first in the class main_thrd, the Thread created by it enters the monitor of object (obj) and locks it.Though new producer(obj) is called first, it is not necessary that the thread created by it gets the lock of object(obj) first. This is false
assumption.
Next, even if we assumed that it gets the lock of given object first,
while(true)
    obj.put(var++);
}The lock of Object(obj) is released when the obj.put(var++) returns and any one can get hold of lock of the Object(obj) at that instant.
In fact, next time obj.put(var++) is called, it will have to wait until it can get lock of the given object.
