Built-in Exceptions in Java
Java defines several exception classes inside the standard package java.lang.
The most general of these exceptions are subclasses of the standard type RuntimeException. Since java.lang is implicitly imported into all Java programs, most exceptions derived from RuntimeException are automatically available.
