Classes in java.lang used by java.io

Exception
The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.

Object
Class Object is the root of the class hierarchy.

Throwable
The Throwable class is the superclass of all errors and exceptions in the Java language.

Classes in java.lang used by java.lang

Class
Instances of the class Class represent classes and interfaces in a running Java application.

ClassNotFoundException
Thrown when an application tries to load in a class through its string name using the forName method in class Class but no definition for the class with the specified name could be found.

Error
An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch.

Exception
The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.

IllegalAccessException
Thrown when an application tries to load in a class, but the currently executing method does not have access to the definition of the specified class, because the class is not public and in another package.

IllegalArgumentException
Thrown to indicate that a method has been passed an illegal or inappropriate argument.

IndexOutOfBoundsException
Thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.

InstantiationException
Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated because it is an interface or is an abstract class.

Integer
The Integer class wraps a value of the primitive type int in an object.

InterruptedException
Thrown when a thread is waiting, sleeping, or otherwise paused for a long time and another thread interrupts it using the interrupt method in class Thread.

NumberFormatException
Thrown to indicate that the application has attempted to convert a string to one of the numeric types, but that the string does not have the appropriate format.

Object
Class Object is the root of the class hierarchy.

Runnable
The Runnable interface should be implemented by any class whose instances are intended to be executed by a thread.

Runtime
Every Java application has a single instance of class Runtime that allows the application to interface with the environment in which the application is running.

RuntimeException
RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.

String
The String class represents character strings.

StringBuffer
A string buffer implements a mutable sequence of characters.

Thread
A thread is a thread of execution in a program.

Throwable
The Throwable class is the superclass of all errors and exceptions in the Java language.

VirtualMachineError
Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating.
