Data read and write from a properties file useful for selenium

Generally in selenium, we used to use properties file for maintaining configuration related data of project like object locators and URL's.
In this post, I will show you how to read and write data from a properties file.

Please find below sample code for the same.

Sample code:
package DriverMethods;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;

public class PropertyFileReader {
Properties prop = new Properties();
FileInputStream file;
FileOutputStream fileOut;

//Reusable method for reading data
public String readingData(String key) throws IOException{

//path of properties file
file = new FileInputStream("path of property file");

// load a properties file
prop.load(file);

//get the value of key
String out=prop.getProperty(key);
return out;

}

//Reusable method for writing data
public void writeData(String key,String data) throws IOException{

//path of properties file
  fileOut = new FileOutputStream("path of property file");

  // set the value to key
  prop.setProperty(key, data);

  // save properties
prop.store(fileOut, null);


}
        //Usage
public static void main(String[] args) throws IOException{
PropertyFileReader Pf = new PropertyFileReader();
System.out.println(Pf.readingData("username"));
Pf.writeData("password", "ShreyaGhosal");
}

}
