Synchronization in Java refers to the ability to control the access of multiple threads to any shared resource. In multithreaded programs, multiple threads may try to access the same resources simultaneously, leading to inconsistent and erroneous results. Synchronization helps prevent thread interference and ensures reliable communication between threads.
Java provides two basic synchronization idioms: synchronized methods and synchronized statements. Synchronized methods enable a simple strategy for preventing thread interference and memory consistency errors. To make a method synchronized, simply add the synchronized keyword to its declaration. Synchronized statements, on the other hand, are more complex and are described in detail in the next section.
Synchronization in Java has several types, including process synchronization and thread synchronization. The synchronization mechanism is developed using the synchronized keyword in Java language, which is built on top of the locking mechanism taken care of by the Java Virtual Machine (JVM) . The synchronized keyword is only applicable for methods and blocks, and not for classes and variables.
In summary, synchronization in Java is a mechanism that allows controlling the access of multiple threads to any shared resource. It helps prevent thread interference and ensures reliable communication between threads. Java provides two basic synchronization idioms: synchronized methods and synchronized statements. There are two types of synchronization methods in Java: process synchronization and thread synchronization.
