The package org is not accessible - Selenium web driver - selenium

Question

I am trying write a selenium code using Java but there is an error package org is not accessible.
I have downloaded a firefox driver and given a path. Please let me know. It will be appreciated.
Please find the code below
package Selenium.webdriver.basictests;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Firsttest {
public static void main(String [] args) {
System.setProperty("webdriver.firefox.marionette","C://Users//97477//.eclipse//geckodriver.exe");
FirefoxDriver driver = new FirefoxDriver();
}
}
SeleniumWebdriverErrors
Please the location of my project folder and let me know the next step because it still showing an error.
Please check the location

Answer 1

Few things:
instead of this:
System.setProperty("webdriver.firefox.marionette","C://Users//97477//.eclipse//geckodriver.exe");
use this:
System.setProperty("webdriver.gecko.driver",Path_of_Firefox_Driver"); // Setting system properties of FirefoxDriver
and
instead of this:
FirefoxDriver driver = new FirefoxDriver();
use this:
WebDriver driver = new FirefoxDriver(); //Creating an object of FirefoxDriver
