Selenium - Create CONFIG file and read it (java)

One of the challenges we face while creating test suite is to put common settings into a file and read it from code as and when neccessary. I did struggle a bit so thought sharing this might help any one who encounters similar problem.

Steps:

1) Create a file say in ur src folder or create a new package config and put a file called config.properties

2) From the file where you want to read create a varaiable like

public

static Properties CONFIG = new Properties();
3) Then load the content into it from the file you have created

FileInputStream fn = new

FileInputStream("path to project"+ \\src\\configure\\config.properties);

CONFIG

.load(fn);

4) Put a value into file config.properties which has to be read 

ex:

#url

mainsite=http://www.rediff.com

5) To read value from file

CONFIG

.getProperty("mainsite");
Some more system properties can be read from system as well
ex: System.getproperty("user.dir") for project


Wil share a sample code some time later but the above steps should help.
