| [BootstrapMethodError](https://developer.android.com/reference/kotlin/java/lang/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](https://developer.android.com/reference/kotlin/java/lang/invoke/CallSite) with a [target](https://developer.android.com/reference/kotlin/java/lang/invoke/CallSite#getTarget()) of the correct [method type](https://developer.android.com/reference/kotlin/java/lang/invoke/MethodHandle#type()), or for a dynamic constant the bootstrap method has failed to provide a constant value of the required type. | | [ClassCircularityError](https://developer.android.com/reference/kotlin/java/lang/ClassCircularityError) | Thrown when the Java Virtual Machine detects a circularity in the superclass hierarchy of a class being loaded. | | [ClassFormatError](https://developer.android.com/reference/kotlin/java/lang/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. | | [ExceptionInInitializerError](https://developer.android.com/reference/kotlin/java/lang/ExceptionInInitializerError) | Signals that an unexpected exception has occurred in a static initializer. | | [IncompatibleClassChangeError](https://developer.android.com/reference/kotlin/java/lang/IncompatibleClassChangeError) | Thrown when an incompatible class change has occurred to some class definition. | | [NoClassDefFoundError](https://developer.android.com/reference/kotlin/java/lang/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. | | [UnsatisfiedLinkError](https://developer.android.com/reference/kotlin/java/lang/UnsatisfiedLinkError) | Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared `native`. | | [VerifyError](https://developer.android.com/reference/kotlin/java/lang/VerifyError) | Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem. | |

|-----------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [AbstractMethodError](https://developer.android.com/reference/kotlin/java/lang/AbstractMethodError) | Thrown when an application tries to call an abstract method. | | [GenericSignatureFormatError](https://developer.android.com/reference/kotlin/java/lang/reflect/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. | | [IllegalAccessError](https://developer.android.com/reference/kotlin/java/lang/IllegalAccessError) | Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to. | | [InstantiationError](https://developer.android.com/reference/kotlin/java/lang/InstantiationError) | Thrown when an application tries to use the Java `new` construct to instantiate an abstract class or an interface. | | [NoSuchFieldError](https://developer.android.com/reference/kotlin/java/lang/NoSuchFieldError) | Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. | | [NoSuchMethodError](https://developer.android.com/reference/kotlin/java/lang/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. | | [UnsupportedClassVersionError](https://developer.android.com/reference/kotlin/java/lang/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. | | 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. ## Summary | Public constructors ||
