In the Multithreading concept, multiple threads try to access the shared resources at a time to produce inconsistent results. The synchronization is necessary for reliable communication between threads.
What is the primary difference between method block and class block *?
Methods are also (generally) named and can be called from elsewhere in your code by that name. Blocks cannot, they can only be reached by following the flow of the code in your class (so generally through calling the method they're contained in and reaching the proper conditions for their execution).
What is the purpose of synchronized method?
Synchronized methods enable a simple strategy for preventing thread interference and memory consistency errors: if an object is visible to more than one thread, all reads or writes to that object's variables are done through synchronized methods.
How does synchronized method work in Java?
1. Synchronized keyword in Java is used to provide mutually exclusive access to a shared resource with multiple threads in Java. Synchronization in Java guarantees that no two threads can execute a synchronized method which requires the same lock simultaneously or concurrently.
