92. Java Race Conditions Explained: The ATM Problem, Multithreading & Thread Safety

Are you struggling to understand concurrency in Java? Race conditions are the "silent, sneaky kind of bug" that can corrupt your data and cause unpredictable application behavior. In this video, we break down one of the most common interview questions in tech: What is a Race Condition? We explore how threads interact with shared mutable state and why simple operations are not always safe. 📌 What you will learn in this lecture: • The ATM Problem: A real-world analogy of two users withdrawing money simultaneously to explain how data corruption happens. • Threads vs. Shared State: Understanding the two main ingredients that cause concurrency issues. • The "Count++" Mystery: Why the increment operation is not atomic and how the CPU handles read-modify-write steps. • The Fix: How to use the Java synchronized keyword to lock methods, force threads to take turns, and achieve Thread Safety. Whether you are debugging a complex backend application or preparing for a Java coding interview, this tutorial will help you write solid, reliable code. -------------------------------------------------------------------------------- #Java #Multithreading #Concurrency #RaceCondition #SoftwareEngineering #CodingInterview
