Java Synchronization

Synchronization in Java:

Java Synchronization is a process of controlling the access of shared resources by the multiple threads in such a manner where 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. Synchronization is best use with the Multi-Threading in Java. Synchronization can be done at two levels:

• Synchronizing a function
• Synchronizing a block of code

Please find the sample code below

Synchronizing a function: 

public synchronized void  Display() 

{
   // related code
}

Synchronizing a block of code inside a function:

 public myFunction ()
{
  synchronized (this)
   {
  // Synchronized code
   }
}
