Available methods in synchronization ?

ZERO

It is a process of ensuring that if two or more threads are using  a shared resource then only one thread get access to that shared resource at a time.

Synchronization contains empty implementation, so no method is used.

In this two threads cannot use the same resource simultaneously beacuse the thread execution gets interrupted or terminated hence only a single thread can share resource at a time.

Synchronization is a process by using Synchronize keyword to prevent the dead lock. This can be used in methods or block to prevent two threads to access the same resource in the same time.
