- ## Uses of LinkageError in java.lang

  Subclasses of LinkageError in java.lang
  Modifier and Type
  Class
  Description
  `class`
  `AbstractMethodError`
  Thrown when an application tries to call an abstract method.
  `class`
  `BootstrapMethodError`
  Thrown to indicate that an `invokedynamic` instruction or a dynamic constant failed to resolve its bootstrap method and arguments, or for `invokedynamic` instruction the bootstrap method has failed to provide a call site with a target of the correct method type, or for a dynamic constant the bootstrap method has failed to provide a constant value of the required 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.

  `GenericSignatureFormatError`
  Thrown when a syntactically malformed signature attribute is encountered by a reflective method that needs to interpret the generic signature information for a class or interface, method or constructor.
