Interface Summary | |
CharSequence | The CharSequence interface represents an ordered set of characters and the functions to probe them. |
Cloneable | This (empty) interface should be implemented by all classes which wish to support cloning. |
Comparable | This interface should be implemented by all classes which wish to define a natural ordering of their instances. |
Iterable | Implementations of this interface can be used within a foreach
statement. |
Runnable | The runnable interface must be implemented by all classes which want to be run as threads. |
Class Summary | |
Character | |
StackTraceElement | An element in a stack trace, as returned by Throwable.getStackTrace() . |
StringBuffer | A string buffer implements a mutable sequence of characters. |
Thread | |
ThreadGroup | |
Throwable | The Throwable class is the superclass of all errors and
exceptions in the Java language. |
Void | The Void class is an uninstantiable placeholder class to hold a reference to the Class object representing the Java keyword void. |
Exception Summary | |
ArithmeticException | This runtime exception is thrown when the an invalid arithmetic operation is attempted. |
ArrayIndexOutOfBoundsException | This runtime exception is 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 | This runtime exception is thrown when a program attempts to store into an array an element of a a type which the array can not hold.. |
ClassCastException | This runtime exception is thrown when a program attempts to cast a an object to a type which it is not compatible with. |
ClassNotFoundException | This exception is thrown when a classloader is unable to find a class. |
CloneNotSupportedException | This exception is thrown when a program attempts to clone an object which does not support the Cloneable interface. |
Exception | This class is the superclass of all classes which represent recoverable exceptions. |
IllegalAccessException | This exception is thrown when a program attempts to access a field or method which is not accessible from the location where the reference is made. |
IllegalArgumentException | This runtime exception is thrown when a method is invoked with an argument which it can not reasonably deal with. |
IllegalMonitorStateException | This runtime exception is thrown when a monitor operation is attempted when the monitor is not in the correct state, for example when a thread attempts to exit a monitor which it did not own. |
IllegalStateException | This runtime exception is thrown when an action is attempted at a time when the virtual machine is not in the correct state. |
IllegalThreadStateException | This runtime exception is thrown when an operation is attempted which is not possible given the state that the executing thread is in. |
IndexOutOfBoundsException | This runtime exception is thrown when a program attempts to access a value in an indexable collection using a value which is outside the possible range of indices. |
InstantiationException | This exception is thrown when a program attempts to access a constructor which is not accessible from the location where the reference is made. |
InterruptedException | This exception is thrown when a waiting thread is activated before the condition it was waiting on has been satisfied. |
NegativeArraySizeException | This runtime exception is thrown when an attempt is made to create an array whose size would be less than zero. |
NoSuchFieldException | This exception is thrown when a program attempts to access a field which does not exist in a class |
NoSuchMethodException | This exception is thrown when a program attempts to access a method which does not exist in a class. |
NullPointerException | This runtime exception is thrown when an attempt is made to access a field or method of an instance or an element of an array when there is no instance or array to use (i.e. the pointer is null). |
NumberFormatException | This runtime exception is thrown when a "string to number" conversion routine is passed an invalid value. |
RuntimeException | This class is the superclass of all classes which represent exceptional conditions which occur as a result of the running of the virtual machine. |
SecurityException | This runtime exception is thrown when a security manager check fails. |
StringIndexOutOfBoundsException | This runtime exception is thrown when the a String is indexed with a value less than zero, or greater than or equal to the size of the array. |
TypeNotPresentException | Indicates that a class, interface, enum or annotation type cannot be found. |
UnsupportedOperationException | This runtime exception is thrown when an unsupported operation is attempted. |
Error Summary | |
AbstractMethodError | This error is thrown when the VM notices that a an attempt is being made to invoke an abstract method. |
AssertionError | Indicates that an assertion has failed. |
ClassCircularityError | This error is thrown when the VM notices that an attempt is made to load a class which would directly or indirectly inherit from one of its subclasses. |
ClassFormatError | This error is thrown by the class loader when it discovers that a class that it is loading does not have the correct shape. |
Error | This class is the superclass of all classes which represent unrecoverable errors. |
ExceptionInInitializerError | This error is thrown when an exception occurs during class initialization. |
IllegalAccessError | This error is thrown when the VM notices that a an attempt is being made to access a field which is not accessable from where it is referenced. |
IncompatibleClassChangeError | This class is the superclass of all classes which represent errors which occur when inconsistant class files are loaded into the same running image. |
InstantiationError | This error is thrown when the VM notices that a an attempt is being made to create a new instance of a class which has no visible constructors from the location where new is invoked. |
InternalError | This error is thrown when the VM notices that it has gotten into a state which it does not understand. |
LinkageError | This class is the superclass of all classes which represent errors that occur when loading and linking class files. |
NoClassDefFoundError | This error is thrown when the VM is unable to locate a class which it has been asked to load. |
NoSuchFieldError | This error is thrown when the VM notices that a an attempt is being made to reference a field of a class which does not exist in that class. |
NoSuchMethodError | This error is thrown when the VM notices that a an attempt is being made to reference a method of a class which does not exist in that class. |
OutOfMemoryError | This error is thrown when a request is made for more memory either as a result of the running program, or because of the internal behavior of the virtual machine which can not be satisfied using the available platform resources. |
StackOverflowError | This error is thrown when the depth of the callstack of the running program excedes some platform or virtual machine specific limit. |
ThreadDeath | ThreadDeath is thrown when a thread stops executing. |
UnknownError | This error is thrown when the virtual machine must throw an error which does not match any known exceptional condition. |
UnsatisfiedLinkError | This error is thrown when an attempt is made to invoke a native for which an implementation could not be found. |
UnsupportedClassVersionError | This error is thrown when an attempt is made to load a class with a format version that is not supported by the VM. |
VerifyError | This error is thrown when the VM notices that an attempt is made to load a class which does not pass the class verification phase. |
VirtualMachineError | This class is the superclass of all classes which represent errors that occur during the operation of the virtual machine. |
