With respect to multithreading, 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 a particular 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 which
may otherwise lead to dirty reads and significant errors.
E.g. synchronizing a function:
public synchronized void Method1 () {
// method code.
}
E.g. synchronizing a block of code inside a function:
public Method2 (){
synchronized (this) {
// synchronized code here.
}
}
