Is it possible to identify a user-defined exception that does not require mandatory handling?

In Java, you can define a custom exception that does not require mandatory handling by creating a class that extends RuntimeException. Such exceptions are called unchecked exceptions and do not require mandatory catching or declaration in the method signature.

Example of a custom unchecked exception:

public class MyUncheckedException extends RuntimeException {
    public MyUncheckedException(String message) {
        super(message);
    }
}

Usage:

throw new MyUncheckedException("Error without mandatory handling");

Thus, a developer can create exceptions that can be thrown without the need to wrap them in try-catch blocks or declare them in throws.
