| class  | AbstractMethodErrorThrown when an application tries to call an abstract method. | 
| class  | AssertionErrorThrown to indicate that an assertion has failed. | 
| class  | BootstrapMethodErrorThrown to indicate that an  invokedynamicinstruction has
 failed to find its bootstrap method,
 or the bootstrap method has failed to provide a
 call site with a target
 of the correct method type. | 
| class  | ClassCircularityErrorThrown when the Java Virtual Machine detects a circularity in the
 superclass hierarchy of a class being loaded. | 
| class  | ClassFormatErrorThrown 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. | 
| class  | ExceptionInInitializerErrorSignals that an unexpected exception has occurred in a static initializer. | 
| class  | IllegalAccessErrorThrown if an application attempts to access or modify a field, or
 to call a method that it does not have access to. | 
| class  | IncompatibleClassChangeErrorThrown when an incompatible class change has occurred to some class
 definition. | 
| class  | InstantiationErrorThrown when an application tries to use the Java  newconstruct to instantiate an abstract class or an interface. | 
| class  | InternalErrorThrown to indicate some unexpected internal error has occurred in
 the Java Virtual Machine. | 
| class  | LinkageErrorSubclasses of  LinkageErrorindicate that a class has
 some dependency on another class; however, the latter class has
 incompatibly changed after the compilation of the former class. | 
| class  | NoClassDefFoundErrorThrown if the Java Virtual Machine or a  ClassLoaderinstance
 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 thenewexpression)
 and no definition of the class could be found. | 
| class  | NoSuchFieldErrorThrown if an application tries to access or modify a specified
 field of an object, and that object no longer has that field. | 
| class  | NoSuchMethodErrorThrown 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. | 
| class  | OutOfMemoryErrorThrown 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. | 
| class  | StackOverflowErrorThrown when a stack overflow occurs because an application
 recurses too deeply. | 
| class  | ThreadDeathAn instance of  ThreadDeathis thrown in the victim thread
 when the (deprecated)Thread.stop()method is invoked. | 
| class  | UnknownErrorThrown when an unknown but serious exception has occurred in the
 Java Virtual Machine. | 
| class  | UnsatisfiedLinkErrorThrown if the Java Virtual Machine cannot find an appropriate
 native-language definition of a method declared  native. | 
| class  | UnsupportedClassVersionErrorThrown 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. | 
| class  | VerifyErrorThrown when the "verifier" detects that a class file,
 though well formed, contains some sort of internal inconsistency
 or security problem. | 
| class  | VirtualMachineErrorThrown to indicate that the Java Virtual Machine is broken or has
 run out of resources necessary for it to continue operating. | 
| Modifier and Type | Class and Description |
