Wrapper classes also provide methods which manipulate or investigate primitives, eg "toBinaryString()", "isJavaIdentifierPart()" and some data eg MAX_VALUE.
Look up the wrapper classes in the API: Boolean, Byte, Character, Double, Float, Long, Integer, Number, Short. I think it unfortunate that two wrapper classes have different names from their primitive counterparts. I have included Number since it is the cuperclass of several of the wrapper classes.
