Same keyword for two purposes in java?

Question

As we use "default" keyword as a access specifier, and it can be used in switch statements as well with complete different purpose, So i was curious that is there any other keywords in java which can be used in more then one purposes

Answer 1

The "default" in the case of access modifier isn't a keyword - you don't write:
default void doSomething()

However, when specifying the default value of an attribute of annotations - it is.

switch (a) {
   default: something();
}

and

public @interface MyAnnotation {
    boolean bool() default true;
}

That, together with final as pointed out by Jon Skeet seems to cover everything. Perhaps except the "overloaded" for keyword:

for (initializer; condition; step) and for (Type element : collection)

Answer 2

You can't use default as an access specifier, so I don't think even that counts. (EDIT: As Bozho pointed out, it can be used in annotations.)

final means "can't be derived from / overridden" and "is read-only" which are two different - but related - meanings.

Answer 3

• default can be used both in a switch and as a default value in an annotation (as pointed out by Bozho)
• final means "can't be derived from / overridden" and "is read-only" which are two different - but related - meanings (as pointed out by Jon)
• extends can be used both to specify the supertype of a class and can be used in wildcards and type variables to put a constraint (related but not exactly the same) (List<? extends Foo>)
• super can be used to specify to something in a superclass of the current class, or in a wildcard to put a constraint (List<? super Foo>)
• static means both "part of the class, not an instance" (for methods, attributes or initializers) and as a static import
• class to declare a class (class Foo {}), or to refer to a class literal (Foo.class) (as answered by ILMTitan)
• (for can be used in a normal for loop and the "enhanced" for, but that's more like overloading (as Bozho puts it so nicely) than really having two meanings)
