First best way is use built-in exception classes wherever possible, you don't need to create your custom exception class to represent every scenario, so try to use existing exception classes

Second best way of handling exception is creating custom exception for specific scenario by extending our class with Exception class.

Consider the following example...

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