13.5 Reserved Words

Table 13.6 lists reserved words in Java. These are keywords or boolean literal values. Note that byvalue, cast, const, future, generic, goto, inner, operator, outer, rest, and var are reserved by Java but currently unused.

Reserved Method Names

Table 13.7 lists the method names of the Object class. Strictly speaking, these method names are not reserved, but since the methods are inherited by every class, they should not be used as the name of a method, except when intentionally overriding an Object method.

clone	getClass	notifyAll
equals	hashCode	toString
finalize	notify	wait
