Introduction

The java.lang.Errors provides for different errors thrown under java lang package.

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 NoClassDefFoundError

This is Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class and no definition of the class could be found.

13 NoSuchFieldError

This is Thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field.

14 NoSuchMethodError

This is 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.

15 OutOfMemoryError

This is Thrown 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.

16 StackOverflowError

This is Thrown when a stack overflow occurs because an application recurses too deeply.

17 ThreadDeath

This is an instance of ThreadDeath is thrown in the victim thread when the stop method with zero arguments in class Thread is called.

18 UnknownError

This is Thrown when an unknown but serious exception has occurred in the Java Virtual Machine.

19 UnsatisfiedLinkError

This is Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.

20 UnsupportedClassVersionError

This is 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.

21 VerifyError

This is Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.

22 VirtualMachineError

This is Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating.
