old way:

use synchronized keyword

Object monitorObject;

synchronized(monitorObject){

//critical section

}

new way: use Lock.lock() and Lock.unlock()

Lock lockObject;

try{

lockObject.lock();

}

finally{

lockObject.unlock();

}

----

old way: use wait() and notify() in the critical section

//insdie your critical section

boolean somecondition;

while(somecondition){

wait();

}

boolean someOtherCondition;

if(someOtherCondition){

notify();

}

new way: use await() and signal() on condition variables

Condition conditionVariable = lockObject.newCondition();

boolean somecondition;

while(somecondition){

conitionVariable.await();

}

boolean someothercondition;

if(someOtherCondition){

conditionVariable.signal();

}
