Java vs C/C++
JVM Instructions 1

Java denotes comments in three ways:

• Double slashes in front of a single line comment:
  
      int i=5; // Set the integer to 5
  
  
• Matching slash-asterisk (/*) and asterisk-slash (*/) to bracket multi-line comments :
  
      /*
        Set the integer to 5
      */
      int i=5;
  
  
• Matching slash-double asterisk (/**) & asterisk-slash(*/) for Javadoc automatic hypertext documentation, as in
  
      /**
        This applet tests graphics.
      */
      public class testApplet extends applet{...
  or
  
      /**
        * Asterisks inside the comment are ignored by javadoc so they
        * can be used to make nice line markers.
       **/
  

The SDK tool javadoc uses the latter /** ..*/ comment style when it produces hypertext pages to describe a class. See the Java 2 API Specifications for examples of javadoc output.

Discuss javadoc further in Chapter 5: Java: Javadoc.
