Synchronized in Java: Thread Safety Guide

In Java, the keyword synchronized is used to achieve synchronized access to shared resources, ensuring consistency of data between multiple threads. By adding the synchronized keyword before a method or code block, a thread can obtain the object’s lock while executing that method or block, forcing other threads to wait until the lock is released before they can proceed.

Using the synchronized keyword can help prevent issues such as inconsistent data or race conditions that may arise when multiple threads concurrently access shared resources. In a multi-threaded environment, ensuring that access to shared resources is synchronized is crucial, and the synchronized keyword is specifically designed to achieve this.
