How This API Document Is Organized

This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.

  • Package

    Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:

    • Interfaces (italic)
    • Classes
    • Enums
    • Exceptions
    • Errors
    • Annotation Types

  • Class/Interface

    Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:

    • Class inheritance diagram
    • Direct Subclasses
    • All Known Subinterfaces
    • All Known Implementing Classes
    • Class/interface declaration
    • Class/interface description
    • Nested Class Summary
    • Field Summary
    • Constructor Summary
    • Method Summary
    • Field Detail
    • Constructor Detail
    • Method Detail

    Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.

  • Annotation Type

    Each annotation type has its own separate page with the following sections:

    • Annotation Type declaration
    • Annotation Type description
    • Required Element Summary
    • Optional Element Summary
    • Element Detail

  • Enum

    Each enum has its own separate page with the following sections:

    • Enum declaration
    • Enum description
    • Enum Constant Summary
    • Enum Constant Detail

  • Use

    Each documented package, class and interface has its own Use page. This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A. You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.

  • Tree (Class Hierarchy)

    There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.

    • When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
    • When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.

  • Deprecated API

    The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.

  • Index

    The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.

  • Prev/Next

    These links take you to the next or previous class, interface, package, or related page.

  • Frames/No Frames

    These links show and hide the HTML frames. All pages are available with or without frames.

  • All Classes

    The All Classes link shows all classes and interfaces except non-static nested types.

  • Serialized Form

    Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.

  • Constant Field Values

    The Constant Field Values page lists the static final fields and their values.

This help file applies to API documentation generated using the standard doclet. Skip navigation links

/**
 * Say that you are writing a computer game that involves a hero who encounters 
 * various monsters. Monsters have several characteristics: hit points, strength, 
 * age, and name. The number of hit points a monster has is how far it is from 
 * death. A monster with a large number of hit points is hard to kill. The hero 
 * also has hit points.

* When the hit points of the hero reach zero, the game is over. The strength of 
* a monster affects how many hit points the hero looses when the monster hits 
* the hero. The age and name of the monster do not affect the outcome of battles
* between the monster and a hero.
 * 
 * 

 Can you make the necessary changes to the Monster class and write a tester 
 * class with main method that will present the hero with monsters in 
 * increasing order of difficulty.
