A Small Java Program For Synchronization

Java offers multiple thread synchronization techniques, each with its advantages synchronized Simple but may cause contention. ReentrantLock More flexible locking mechanism. Semaphore Controls access with limited permits. ReadWriteLock Efficient for read-heavy operations. Atomic variables Best for lock-free counters.

In this post, we feature a comprehensive article on Java Synchronized Blocks. Java synchronized keyword marks a block or method a critical section.A critical section is where one and only one thread is executing at a time, and the thread holds the lock for the synchronized section.. Java is multi-threaded language where multiple threads runs parallel to complete their execution.

Explanation Two threads, t1 and t2, increment the shared counter variable concurrently.The inc and get methods are synchronized, meaning only one thread can execute these methods at a time, preventing race conditions. The program ensures that the final value of the counter is consistent and correctly updated by both threads. Need of Synchronization

Need of Thread Synchronization? When we start two or more threads within a program, there may be a situation when multiple threads try to access the same resource and finally they can produce unforeseen result due to concurrency issues. For example, if multiple threads try to write within a same file then they may corrupt the data because one of the threads can override data or while one

First, we will see the basic theory about the synchronization concept, and then we will see an example of its implementation in Java. Let's start the tutorial. Important Point about Synchronization. Below is some important point about Synchronization in Java Synchronized is the keyword which is used to implement Synchronization in Java.

Synchronization in Java is possible by using java keyword quotsynchronizedquot and quotvolatilequot. Concurrent access of shared objects in Java introduces to kind of errors thread interference and memory consistency errors and to avoid these errors you need to properly synchronize your java object to allow mutual exclusive access of critical section to

That's exactly what can happen in a Java program when multiple threads try to access shared resources simultaneously. This is where synchronization comes to the rescue! Synchronization in Java is like having a traffic cop in that busy kitchen, ensuring that only one chef thread can use a particular ingredient resource at a time.

The code in Java program can be synchronized with the help of a lock. A lock has two operations acquire and release. The process of acquiring and releasing object lock monitor of an object is handled by Java runtime system JVM.. In Java programming language, every object has a default object lock that can be used to lock on a thread.

Static synchronization - In the case of static synchronized method it will lock the class instead of the object since static belongs to class level. Static synchronized means Only one thread can access the class at one time. That's all about Synchronization In Java With Example. You may like. Runnable interface in java.
