Generic class names to avoid

Java (Oracle Java update 2) has many classes with the same generic name. To avoid further confusion, I suggest avoiding these names if you can.

Most repeated

The following class names are repeated, 19 Handler, 16 Messages, 13 Util, 10 Element, 8 Attribute, 7 SecuritySupport, 7 Node, 6 Provider, 6 Header, 6 FactoryFinder, 6 Document. 5 SOAPBinding, 5 Repository, 5 Ref, 5 ORB, 5 Name, 5 Constants, 5 Connection, 5 Comment, 5 Binding, 5 Attributes,
This excludes the Apache XML library which repeats many names. If you include these libraries there are 26 classes called SecuritySupport.

 

Four times

Window, Version, Utility, Timer, Text, State, Signature, ServiceName, ServiceConfigurationError, Service, ResourceLoader, Queue, Policy, Parser, Operation, NativeLibLoader, Message, Label, JSObject, GetPropertyAction, FactoryFinder$ConfigurationError, Event, ConstantPool, AppletAudioClip, Action,

 

Three times

XMLWriter, Wrapper, WildcardTypeImpl, Visitor, Validator, Types, TypeMismatch, TypeInfo, Type, Trace, Token, Timestamp, Target, Symbol, StyleSheet, SOAPFault, SOAPConstants, Scope, Schema, ResourceManager, Resource, Resolver, Request, Reference, Properties, ProgressMonitor, PrincipalImpl, Principal, Port, PooledConnection, Pool, Pipe, Patcher, ParseException, OutputStream, ObjectStreamField, Navigator, NamespaceSupport$Context, NamespaceSupport, MimeType, MemoryCache, MarshalException, Manifest, Main, Location, List, JarVerifier, IOR, Invoker, InvalidName, Introspector, InputStream, Import, ImageCache, HTMLDocument, HTMLCollection, Headers, FinalArrayList, Filter, FileSystem, FactoryImpl, Extension, EventListener, ErrorHandler, Entity, EncryptedPrivateKeyInfo, Delegate, DataSource, CurrentOperations, CurrentHelper, Current, Counter, Context, ContentType, Config, Code, CharacterData, Certificate, CacheTable, Cache, Bridge, Base64, Authenticator, AttributeList, ArrayType, Array, AppletAudioClip$1, Annotation,

 

Appearing twice

Too many to mention.
