Differences and connections between sleep and wait in Java

1 Object Monitor

Every object in Java has an intrinsic lock, which is called the object Monitor.

Like method, the method, it also has a monitor. All, if a method adds the Synchronized keyword, a thread entering this method actually gets the monitor of this method.

Again, we can use the current object's monitor, the This keyword.

Again, we can create an object objects by ourselves and then syncronized (object), because each object has an object monitor that is designed to facilitate synchronization between threads.

So, Java is everything is object, everything has a lock.
