Java's Exception Classes
The class Exception is the superclass of the classes designed to handle exceptions.
There are various types of exceptions, such as I/O exceptions, input mismatch
exceptions, number format exceptions, file not found exceptions, and array index
out of bounds exceptions. Java categorizes these exceptions into separate classes.
These predefined exception classes are contained in various packages. The class
Exception is contained in the package java.lang .TheclassestodealwithI/O
exceptions, such as the file not found exception, are contained in the package
java.io .Similarly,theclassestodealwithnumber format exceptions and arithmetic
exceptions, such as division by zero, are contained in the package java.lang .
Generally, exception classes are placed in the package that contains the methods that
throw these exceptions.
The class Exception is very simple. It only contains two constructors, as shown in
Table 11-2.
