class Error extends Throwable An Error is a subclass of Throwable that indicates serious problems that a reasonable application should error message java not try to catch. Most such errors are abnormal conditions. The ThreadDeath error, though a "normal" condition, is also a subclass of Error because most applications should not try to catch it. A method is not required to declare error 500 java in its throws clause any subclasses of Error that might be thrown during the execution of the method but not caught, since these errors are abnormal conditions that should never occur. That is, Error and its subclasses are regarded as unchecked exceptions for the purposes of compile-time checking of exceptions.

Exceptions are the bread and butter of exception handling. The Javadoc explains it well: An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. Look at a few of the subclasses of Error, taking some of their JavaDoc comments: AnnotationFormatError - Thrown when the annotation parser attempts to read an annotation from a class file and determines that the annotation is malformed. AssertionError - Thrown to indicate that an assertion has failed. 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. VirtualMachineError - Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating. There

Error Summary S.N.Error & Description 1 AbstractMethodError This is Thrown when an application tries to call an abstract method. 2AssertionError This is Thrown to indicate that an assertion has failed. 3 ClassCircularityError This is Thrown when a circularity has been detected while initializing a class. 4 ClassFormatError This is 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. 5 Error This is an Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. 6 ExceptionInInitializerError These are the Signals that an unexpected exception has occurred in a static initializer. 7 IllegalAccessError This is Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to 8 IncompatibleClassChangeError This is Thrown when an incompatible class change has occurred to some class definition. 9 InstantiationError This is Thrown when an application tries to use the Java new construct to instantiate an abstract class or an interface. 10 InternalError This is Thrown to indicate some unexpected internal error has occurred in the Java Virtual Machine. 11 LinkageError The Subclasses of LinkageError indicate that a class has some dependency on another class. 12 NoClass
