Java Comments

/*

Java Comments:

A description about a basic programming element is called comment. Comments are meant for developer to understand the purpose.

Types of comments:

Java supports 3 types of comments

1. Single Line comment (//).

2. Multiline comment (/*    */).

3. Document comment (/**   */).

The statements placed inside these special characters are ignored by compiler while compling the class. It means, compiler will not generate bytecodes for those comments. So comments are not appeared in .class file.

Below program shows usage of all above 3 comments.
