What I have tried:

This is my main class

package Project;

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class base {

public WebDriver driver;
public WebDriver initializeDriver() throws IOException
{
Properties prop=new Properties();
FileInputStream fi=new FileInputStream("C:\\Users\\M SHASHIDHAR REDDY\\java-project\\src\\main\\java\\Project\\data.properties");
prop.load(fi);
String browserName=prop.getProperty("browser");
if(browserName.equals("chrome"))
{
System.setProperty("webdriver.chrome.driver", "E:\\seleniumog\\chromedriver.exe");
driver = new ChromeDriver();
}
else if(browserName.equals("firefox"))
{
System.setProperty("webdriver.gecko.driver", "F:\\selenium org\\geckodriver.exe");
driver= new FirefoxDriver();
}
return driver;



}

}


This is my test class

package Project;

import java.io.IOException;

import org.testng.annotations.Test;

public class HomePage extends base{


@Test
public void basePageNavigation() throws IOException
{
driver =initializeDriver();
driver.get("https://gmail.com/");


}


}
