  1. Javadoc CSCI 142

  2. Documentation • Not a programmer's first love • Usually lives in a separate file somewhere • Often a deliverable on the schedule • Not updated when program is changed • Incorrect documentation may be worse than none

  3. Javadoc • API documentation is included in the source code as comments • The javadoc program analyzes the source code and produce formatted html documentation • Same style as Standard API documentation • Hopefully, programmers update documentation when they change the code

  4. Javadoc Comments • Block comments introduced with /** and end with */ • May include html formatting tags • Placed immediately ahead of public class and method definitions • Document all public elements • Describe what the class/method does, not implementation details

  5. Class Documentation • @author tag for programmer name • @version tag for program version /** * Represents a <i>student</i> at a * university. * @author Bill * @version 1.2 */ public class Student {

  6. Method Documentation • up to first period included in method summary • everything included in detail documentation • @param tag to describe each parameter • @return tag if not void • tags go after text, do not specify data type /** * Adds a course grade to the student's record. * Updates both <i>gpa</i> and <i>credits</i>. * @param grade the course grade * @param credits the course credits * @return the new <i>gpa</i> */ public double addGrade(double grade, int credits) {

  7. To Run Javadoc • at the DOS prompt: • javadoc -version -author -public Student.java • creates numerous html files: • Student.java allclasses-noframe.html • constant-values.html index.html • overview-tree.html packages.html • index-all.html Student.html • deprecated-list.html package-list • allclasses-frame.html help-doc.html • on-line documentation for javadoc: • http://java.sun.com/j2se/1.4/docs/tooldocs/win32/javadoc.html
