Names of class types should be descriptive nouns or noun phrases, not overly long, in mixed case with the first letter of each word capitalized. For example:
ClassLoaderSecurityManagerThreadDictionaryBufferedInputStream
Likewise, names of interface types should be short and descriptive, not overly long, in mixed case with the first letter of each word capitalized. The name may be a descriptive noun or noun phrase, which is appropriate when an interface is used as if it were an abstract superclass, such as interfaces java.io.DataInput and java.io.DataOutput; or it may be an adjective describing a behavior, as for the interfaces java.lang.Runnable and java.lang.Cloneable.
Hiding involving class and interface type names is rare. Names of fields, parameters, and local variables normally do not hide type names because they conventionally begin with a lowercase letter whereas type names conventionally begin with an uppercase letter.
