Interface Summary

Interface	Description
AutoCloseable	Defines an interface for classes that can (or need to) be closed once they are not used any longer.
Comparable<T>	This interface should be implemented by all classes that wish to define a natural order of their instances.
Iterable<T>	Instances of classes that implement this interface can be used with the enhanced for loop.
Runnable	Represents a command that can be executed.

Class Summary

Class	Description
Boolean	The wrapper for the primitive type boolean.
BString	This is the base class for our optimized version of strings.
Byte	The wrapper for the primitive type byte.
Character	The wrapper for the primitive type char.
Class<T>	The in-memory representation of a Java class.
Double	The wrapper for the primitive type double.
Enum<E extends Enum<E>>	The superclass of all enumerated types.
Float	The wrapper for the primitive type float.
Integer	The wrapper for the primitive type int.
Long	The wrapper for the primitive type long.
Math	Class Math provides basic math constants and operations such as trigonometric functions, hyperbolic functions, exponential, logarithms, etc.
Number	The abstract superclass of the classes which represent numeric base types (that is Byte, Short, Integer, Long, Float, and Double.
Object	The root class of the Java class hierarchy.
Short	The wrapper for the primitive type short.
String	An immutable sequence of characters/code units (chars).
System	Provides access to system-related information and resources including standard input and output.
Throwable	The superclass of all classes which can be thrown by the VM.

Exception Summary

Exception	Description
ArithmeticException	Thrown when the an invalid arithmetic operation is attempted.
ArrayIndexOutOfBoundsException	Thrown when the an array is indexed with a value less than zero, or greater than or equal to the size of the array.
ArrayStoreException	Thrown when a program attempts to store an element of an incompatible type in an array.
ClassCastException	Thrown when a program attempts to cast a an object to a type with which it is not compatible.
ClassNotFoundException	Thrown when an application tries to load in a class through its string name using: The forName method in class Class.
Exception	Exception is the superclass of all classes that represent recoverable exceptions.
IllegalArgumentException	Thrown when a method is invoked with an argument which it can not reasonably deal with.
IndexOutOfBoundsException	Thrown when a program attempts to access a value in an indexable collection using a value which is outside of the range of valid indices.
NegativeArraySizeException	Thrown when an attempt is made to create an array with a size of less than zero.
NoSuchFieldException	Thrown when the VM notices that a program tries to reference, on a class or object, a field that does not exist.
NoSuchMethodException	Thrown when the VM notices that a program tries to reference, on a class or object, a method that does not exist.
NullPointerException	Thrown when a program tries to access a field or method of an object or an element of an array when there is no instance or array to use, that is if the object or array points to null.
NumberFormatException	Thrown when an invalid value is passed to a string-to-number conversion method.
ReflectiveOperationException	Superclass of exceptions related to reflection.
RuntimeException	RuntimeException is the superclass of all classes that represent exceptional conditions which occur as a result of executing an application in the VM.

Error Summary

Error	Description
Error	Error is the superclass of all classes that represent unrecoverable errors.
IncompatibleClassChangeError	IncompatibleClassChangeError is the superclass of all classes which represent errors that occur when inconsistent class files are loaded into the same running image.
LinkageError	LinkageError is the superclass of all error classes that occur when loading and linking class files.
NoSuchFieldError	Thrown when the VM notices that a program tries to reference, on a class or object, a field that does not exist.
NoSuchMethodError	Thrown when the VM notices that a program tries to reference, on a class or object, a method that does not exist.
