Absolute path:

The absolute path is the real path of the file or directory on your home page on the hard disk, (URL and physical path )For example: C:\xyz\test.txt represents the absolute path of the test.txt file. http://www.sun.com/index.htm also represents an absolute URL path.

Relative path:

The path relative to a certain base directory. Contains the relative path of the Web (relative directory in HTML). For example: in Servlet, "/" represents the root directory of the Web application.
