What do you understand by Synchronization?

Answer:

Synchronization is a process of controlling the access of shared resources by the multiple threads in such a manner that only one thread can access one resource at a time. In non synchronized multithreaded application, it is possible for one thread to modify a shared object while another thread is in the process of using or updating the object's value. Synchronization prevents such type of data corruption.
E.g. Synchronizing a function:
public synchronized void Method1 () {
    // Appropriate method-related code.
}
E.g. Synchronizing a block of code inside a function:
public myFunction (){
    synchronized (this) {
    // Synchronized code here.
  }
}
