Java 1.2 | cloneable collection | This class is a java.util.Map that maps the attribute names of a JAR file manifest to arbitrary string values. The JAR manifest format specifies that attribute names can contain only the ASCII characters A to Z (uppercase and lowercase), the digits 0 through 9, and the hyphen and underscore characters. Thus, this class uses Attributes. Name as the type of attribute names, in addition to the more general String class. Although you can create your own Attributes objects, you more commonly obtain Attributes objects from a Manifest .
