What reasons make the use of System.exit method undesirable in your application?

Using the System.exit() method in Java is undesirable for several reasons:

• Forcing JVM termination: System.exit() immediately terminates the Java virtual machine, which can lead to improper application shutdown.
• Bypassing finally blocks and shutdown hooks: When System.exit() is called, finally blocks and cleanup methods may not execute, leading to resource leaks or data loss.
• Breaking logical flow: In multithreaded applications, calling System.exit() will terminate all threads, which can be unexpected and cause errors.
• Testing and integration issues: In environments where the application runs inside containers or application servers, calling System.exit() can stop the entire server.

Therefore, it is better to use proper shutdown mechanisms, such as closing resources correctly and allowing the main thread to finish naturally.
