Custom Error
A custom error is an error that is specific to a particular program or application. It is not related to any external factors, such as the operating system or the Java virtual machine. Custom errors are handled by the program that encountered them, and they provide information about the error to the user or developer.
Example:
java
public class CustomError extends Exception {
public CustomError(String message) {
super(message);
}
}
In this example, the CustomError class inherits from the Exception class. This allows the CustomError to extend the functionality of the Exception class and provide a specific error message.
Benefits of Custom Errors:
Control flow: Custom errors allow you to handle them gracefully and provide feedback to the user or developer.
Code consistency: Custom errors help maintain code consistency by enforcing specific error handling conventions.
Improved debugging: When an error occurs, custom errors provide additional information about the error, which can be helpful for debugging.
Additional Points:
Custom errors can be declared at the class or method level.
They can be used to handle specific exceptions or a range of exceptions.
Custom errors can be declared with a custom message, a cause, and a stack trace
