What is the limitation of using the volatile keyword in Java or another programming language?

The volatile keyword in Java guarantees visibility of variable changes between threads, meaning reads will always occur from main memory rather than from the CPU cache. However, volatile does not ensure atomicity of operations and is not suitable for complex synchronized actions.

Limitations of using volatile:

• Not suitable for increments or other compound operations, as they are not atomic.
• Does not replace full synchronization mechanisms (such as synchronized or Lock) when mutual exclusion is needed.
• Does not guarantee the order of execution of operations, except for the variable itself.

Thus, volatile is useful for flags or status indicators but not for protecting complex critical sections.
