Volatile keyword in Java || Interview Question

Hey everyone! Today, let’s talk about the volatile keyword in Java.

What is volatile?
The volatile keyword in Java is used to indicate that a variable’s value will be modified by different threads. It ensures that changes to a variable are immediately visible to all threads.

Why Use volatile?
In a multithreaded environment, threads may cache variables, leading to inconsistent views of the variable’s value. Declaring a variable as volatile ensures that it is always read from and written to the main memory, providing visibility guarantees across threads.

Benefits:
Visibility: Guarantees that changes to a variable are visible to all threads.
Simplicity: Easier to use than synchronization for simple flags or state indicators.

Limitations:
Atomicity: volatile does not guarantee atomicity. For compound actions, you still need synchronization.
Performance: May introduce some performance overhead due to memory synchronization.
