how to use synchronization in java

Question

Accepted Answer

Synchronization in Java is used to control access to shared resources by multiple threads.

Synchronization can be achieved using synchronized keyword or locks.
It ensures that only one thread can access the shared resource at a time.
Synchronization can be applied to methods or blocks of code.
Example: synchronized void method() { //code }
Example: synchronized(obj) { //code }

Accepted Answer

Synchronization is a mechanism in Java that is used to control access to shared resources in a multithreaded environment. It is used to prevent two or more threads from accessing a shared resource at the same time, which can lead to race conditions and other synchronization problems.

There are several ways to use synchronization in Java:

Synchronized methods: A synchronized method is a method that is marked with the synchronized keyword. When a thread enters a synchronized method, it acquires the lock for the object that the method belongs to. This prevents other threads from accessing the object until the thread exits the method.

Synchronized blocks: A synchronized block is a block of code that is marked with the synchronized keyword and is enclosed in curly braces. It can be used to synchronize access to a specific resource.

java.util.concurrent.locks package: The java.util.concurrent.locks package provides several classes that can be used to synchronize access to resources in a more flexible way than is possible with synchronized methods and blocks. These classes include ReentrantLock, ReadWriteLock, and Condition.
