Q) What is PATH?




A)
->path is an environment variable used by os to locate softwares.
->path variable can have more than one value separated by semicolon (;).
->to specify to the os the location of java softwares, we need to store its location in path variable( such storing business is called setting the path) so whenever execute java commands then os recognize that.
->we store java software location into path variable in 2 ways
1. Dos prompt (temporary store)
2. through system variable (permanent store)
->At the dos prompt we set path as fallows
SET PATH =C:\programs files\java\jdk1.6.0\bin
->for permanent storage of environmental variable.
(Right click on my computer->properties->advanced->Environmental variable->select path->edit is clicking->post the C:\programs files\java\jdk1.6.0\bin into storing of the actual path and click ok.)

Q) What is the purpose of JDBC?

A) -> Java application can do any task by making a method (function) call. ->java method calls are not understandable to database management system.
