How can I implement custom exception handling in Java?

How can I implement custom exception handling in Java?

You can create a custom exception by extending the Exception class. Here's a simple example:

public class MyCustomException extends Exception {
    public MyCustomException(String message) {
        super(message);
    }
}

What should I do after creating the custom exception?

After creating the custom exception, you can throw it in your code using the throw keyword. For example:

if (someCondition) {
    throw new MyCustomException("Something went wrong!");
}

How do I catch this custom exception?

You can catch your custom exception using a try-catch block like this:

try {
    // code that may throw MyCustomException
} catch (MyCustomException e) {
    System.out.println(e.getMessage());
}

Can I have multiple catch blocks for different exceptions?

Yes, you can have multiple catch blocks for different exceptions. Just ensure that the more specific exceptions are caught before the more general ones.
