Classes in java.lang used by java.io
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`.
Comparable This interface imposes a total ordering on the objects of each class that implements it.
Exception The class `Exception` and its subclasses are a form of `Throwable` that indicates conditions that a reasonable application might want to catch.
IllegalArgumentException Thrown to indicate that a method has been passed an illegal or inappropriate argument.
Object Class `Object` is the root of the class hierarchy.
SecurityException Thrown by the security manager to indicate a security violation.
String The `String` class represents character strings.
Throwable The `Throwable` class is the superclass of all errors and exceptions in the Java language.

Classes in java.lang used by java.lang

Byte The Byte class is the standard wrapper for byte values.

Character.UnicodeBlock A family of character subsets representing the character blocks defined by the Unicode 2.0 specification.
Class Instances of the class `Class` represent classes and interfaces in a running Java application.

ClassLoader The class `ClassLoader` is an abstract class.
ClassNotFoundException Thrown when an application tries to load in a class through its string name using: The `forName` method in class `Class`.
CloneNotSupportedException Thrown to indicate that the `clone` method in class `Object` has been called to clone an object, but that the object's class does not implement the `Cloneable` interface.
Comparable This interface imposes a total ordering on the objects of each class that implements it.

Float The Float class wraps a value of primitive type `float` in an object.
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.
IncompatibleClassChangeError Thrown when an incompatible class change has occurred to some class definition.
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`.
LinkageError Subclasses of `LinkageError` indicate that a class has some dependency on another class; however, the latter class has incompatibly changed after the compilation of the former class.
Long The Long class wraps a value of the primitive type `long` in an object.
NoSuchFieldException Signals that the class doesn't have a field of a specified name.
NoSuchMethodException Thrown when a particular method cannot be found.
Number The abstract class `Number` is the superclass of classes `Byte`, `Double`, `Float`, `Integer`, `Long`, and `Short`.

Object Class `Object` is the root of the class hierarchy.
Package `Package` objects contain version information about the implementation and specification of a Java package.
Process The `Runtime.exec` methods create a native process and return an instance of a subclass of `Process` that can be used to control the process and obtain information about it.
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.
