| Package | Description |
|---|---|
| java.lang |
Provides classes that are fundamental to the design of the Java programming language.
|
| java.lang.reflect |
Provides classes and interfaces for obtaining reflective information about classes and objects.
|
| Modifier and Type | Class and Description |
|---|---|
class |
AbstractMethodError
Thrown when an application tries to call an abstract method.
|
class |
BootstrapMethodError
Thrown to indicate that an
invokedynamic instruction 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 |
ClassCircularityError
Thrown when the Java Virtual Machine detects a circularity in the superclass hierarchy of a class being loaded.
|
class |
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.
|
class |
ExceptionInInitializerError
Signals that an unexpected exception has occurred in a static initializer.
|
class |
IllegalAccessError
Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
|
class |
IncompatibleClassChangeError
Thrown when an incompatible class change has occurred to some class definition.
|
class |
InstantiationError
Thrown when an application tries to use the Java
new construct to instantiate an abstract class or an interface.
|
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.
|
class |
NoSuchFieldError
Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field.
|
class |
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.
|
class |
UnsatisfiedLinkError
Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared
native.
|
class |
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.
|
class |
VerifyError
Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.
|
| Modifier and Type | Class and Description |
|---|---|
class |
GenericSignatureFormatError
Thrown when a syntactically malformed signature attribute is encountered by a reflective method that needs to interpret the generic signature information for a type, method or constructor.
