Understanding User Defined Exception in Java

User-Defined Exceptions in JavaUser-defined exceptions in Java are exceptions that you create to handle specific error conditions in your code. These exceptions allow you to define and raise customized error messages that better convey the nature of the problem occurring in your program.

A user-defined exception in Java is a custom exception that you create by extending the Exception class or any of its subclasses. These are specifically designed to handle scenarios specific to your application’s business logic or operational logic.

On the other hand, we can also create user-defined unchecked exceptions by extending the RuntimeException class. Unchecked exceptions do not require explicit handling, and the compiler does not enforce catching or declaring them, making them more convenient for certain situations.

While creating user-defined exceptions, it is generally recommended to create unchecked exceptions by extending the RuntimeException class. This is because checked exceptions may impose more boilerplate code, making the code less concise and more cumbersome to handle in some scenarios.

By creating user-defined exceptions, we can add meaningful and informative error messages to our applications, improving code readability and helping us identify and handle specific error conditions more effectively.
