In this article we will show you the solution of user defined exception example in java, an issue that arose during the course of a program's execution—a run-time error—is an exception.

When an exception occurs, the programme is terminated abruptly, and the code following the line that caused the exception is never executed.

Java provides us with the ability to create our own exceptions because they are essentially derived classes of Exceptions.

Custom or user-defined exceptions are exceptions that we define ourselves. Java custom exclusions are used to customise the exception to the user's needs.

An exception that is thrown with the keyword "throw" is referred to as custom exceptions or user-defined exceptions.

Java exceptions cover almost every type of typical exception that might occur while programming.

To identify and treat a subset of current Java exceptions. and give them particular treatment.

Exceptions in business logic: These are the workflow and business logic exceptions.

It helps application users and developers understand the specific problem.

The Exception class from the java.lang package must be extended in order to produce a unique exception.

The ArithmeticException and NullPointerException exception classes have already been defined in Java.

These exclusions are already configured to be triggered by predefined conditions, such as the ArithmeticException being triggered when a number is divided by zero.

With us, our own exception classes can be created in Java, and we can raise those exceptions by using the throw keyword.

Custom as well as user-defined exceptions are the name given to these exceptions.

Java has a few built-in exceptions,which are further classified as compile-time as well as runtime exceptions.

While waiting on one of the built-in exceptions to satisfy our use case, we are living in a "sunny day" scenario.

Custom exceptions are another name for user-defined exceptions. The exceptions made specifically for our use case and thrown with the throw keyword seem to be user-defined exceptions, and they're derived classes of an Exception class from the java.lang package.

Custom exceptions give programmers the freedom to include messages as well as methods that aren't already a part of an Exception class.

The use case-specific messages are typically used to show exceptions or to store status codes or error codes based on the use case overriding an existing process.

When creating custom exceptions for business logic, they are useful. It assists application developers in better understanding the business-specific exception.

Step By Step Guide On User Defined Exception Example In Java :-

class TalkersCode{
    public demo(String s)
    {
        super(s);
    }
}
public class Main {
    public static void main(String args[])
    {
        try {
            throw new exceptiondemo("TalkersCode");
        }
        catch (exceptiondemo) {
            System.out.println("Print");
            System.out.println(ex.getMessage());
        }
    }
}

1. Design a Class to represent a user-defined exception.
2. We then create the parent Exception's Call function Object() { [native code] }.
3. Following the creation of A Class that makes use of the aforementioned MyExceptiondemo,
4. Then we throw a user-defined exception object.
5. Finally, humans print a message from of the MyExceptiondemo object.

Conclusion :-

The ArithmeticException and NullPointerException exception classes have already been defined in Java.

These exclusions are already configured to be triggered by predefined conditions, such as the ArithmeticException being triggered when a number is divided by zero.

I hope this article on user defined exception example in java helps you and the steps and method mentioned above are easy to follow and implement.
