Interface Summary

Interface	Description
Appendable	An object to which char sequences and values can be appended.
AutoCloseable	A resource that must be closed when it is no longer needed.
CharSequence
Cloneable	A class implements the Cloneable interface to indicate to the Object.clone() method that it is legal for that method to make a field-for-field copy of instances of that class.
Comparable<T>
Iterable<T>	Implementing this interface allows an object to be the target of the "foreach" statement.
Readable	This interface is only defined for hierarchy compatibility.
Runnable	The Runnable interface should be implemented by any class whose instances are intended to be executed by a thread.
Thread.UncaughtExceptionHandler	Interface for handlers invoked when a Thread abruptly terminates due to an uncaught exception.

Number	The abstract class Number is the superclass of classes BigDecimal, BigInteger, Byte, Double, Float, Integer, Long, and Short.
Object	Class Object is the root of the class hierarchy.
Package	Package represent a Java package.

String
StringBuffer	A thread-safe, mutable sequence of characters.
StringBuilder	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.

Enum Summary

Enum	Description
Thread.State	A thread state.

Exception Summary

Exception	Description
ArithmeticException	Thrown when an exceptional arithmetic condition has occurred.
ArrayIndexOutOfBoundsException	Thrown to indicate that an array has been accessed with an illegal index.
ArrayStoreException	Thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects.
ClassCastException	Thrown to indicate that the code has attempted to cast an object to a subclass of which it is not an instance.
ClassNotFoundException	Thrown when an application tries to load in a class through its string name using: The forName method in class Class.
CloneNotSupportedException
Exception	The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.
IllegalAccessException	An IllegalAccessException is thrown when an application tries to reflectively create an instance (other than an array), set or get a field, or invoke a method, but the currently executing method does not have access to the definition of the specified class, field, method or constructor.
IllegalArgumentException	Thrown to indicate that a method has been passed an illegal or inappropriate argument.
IllegalMonitorStateException	Thrown to indicate that a thread has attempted to wait on an object's monitor or to notify other threads waiting on an object's monitor without owning the specified monitor.
IllegalStateException	Signals that a method has been invoked at an illegal or inappropriate time.
IllegalThreadStateException	Thrown to indicate that a thread is not in an appropriate state for the requested operation.
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.
InterruptedException	Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity.
NegativeArraySizeException	Thrown if an application tries to create an array with negative size.
NoSuchFieldException	Signals that the class doesn't have a field of a specified name.
NoSuchMethodException	Thrown when a particular method cannot be found.
NullPointerException	Thrown when an application attempts to use null in a case where an object is required.
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.
ReflectiveOperationException	Common superclass of exceptions thrown by reflective operations in core reflection.
RuntimeException	RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.
SecurityException	Thrown by the security manager to indicate a security violation.
StringIndexOutOfBoundsException	Thrown by String methods to indicate that an index is either negative or greater than the size of the string.
UnsupportedOperationException	Thrown to indicate that the requested operation is not supported.

Error Summary

Error	Description
AbstractMethodError	Thrown when an application tries to call an abstract method.
AssertionError	Thrown to indicate that an assertion has failed.
ClassCircularityError	Thrown when the Java Virtual Machine detects a circularity in the superclass hierarchy of a class being loaded.
ClassFormatError	Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file.
Error	An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch.
ExceptionInInitializerError	Signals that an unexpected exception has occurred in a static initializer.
IllegalAccessError	Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
IncompatibleClassChangeError	Thrown when an incompatible class change has occurred to some class definition.
InstantiationError	Thrown when an application tries to use the Java new construct to instantiate an abstract class or an interface.
InternalError	Thrown to indicate some unexpected internal error has occurred in the Java Virtual Machine.
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.
NoClassDefFoundError	Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.
NoSuchFieldError	Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field.
NoSuchMethodError	Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.
OutOfMemoryError	Thrown when the Java Virtual Machine cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.
StackOverflowError	Thrown when a stack overflow occurs because an application recurses too deeply.
UnknownError	Thrown when an unknown but serious exception has occurred in the Java Virtual Machine.
UnsatisfiedLinkError	Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.
UnsupportedClassVersionError	Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported.
VerifyError	Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.
VirtualMachineError	Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating.

Annotation Types Summary

Annotation Type	Description
Deprecated	A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists.
Override	Indicates that a method declaration is intended to override a method declaration in a supertype.
SafeVarargs	A programmer assertion that the body of the annotated method or constructor does not perform potentially unsafe operations on its varargs parameter.
SuppressWarnings	Indicates that the named compiler warnings should be suppressed in the annotated element (and in all program elements contained in the annotated element).
