Why is it Crucial to Minimize the Use of Synchronized Methods in Java?

Introduction:

In the world of multithreading and concurrent programming in Java, one of the key concerns that developers face is ensuring thread safety. Synchronized methods in Java provide a solution to this problem by guaranteeing that only one thread can access a method at a time. However, this comes with certain performance and scalability issues that can impact the overall efficiency of an application. In this article, we will delve into the reasons why it is important to minimize the use of synchronized methods, explore alternatives, and understand the trade-offs associated with synchronization in Java.

Understanding Synchronized Methods:

A synchronized method in Java is a method that can be accessed by only one thread at a time. This is achieved by using the synchronized keyword. The purpose of synchronized methods is to prevent race conditions, which occur when two or more threads attempt to modify shared resources simultaneously, leading to inconsistent results.
