Defining Exceptions

Programmers can define their own exception

types and write code to throw them and catch

them.

Example with Attributes and Values:

public class NoSuchAttributeException extends Exception

{

public String attrName;

public Object newValue;

NoSuchAttributeException(String name, Object value) {

super("No attribute named \"" + name + "\" found");

attrName = name;

newValue = value;

}

}
