Null pointer exception in webdrivermanager

Question

package base;

import java.util.concurrent.TimeUnit;

public class Page{
    
    public static WebDriver driver;
     
    public Page() {
        if(driver==null) {
          WebDriverManager.chromedriver().setup();
          driver.get("https://www.zoho.com/");
          driver.manage().window().maximize();
          driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        }
    }
}

`driver` is still `null` by the time you are calling `driver.get()`. You need to initialize it to an actual `WebDriver` object. — Dev Yego, Jul 19 '20 at 07:07

The driver inside if(driver == null){..} will ofcourse be null and when you are trying to do driver.get("https://www.zoho.com/"); you are getting NPE.

You have forgot to assign to the driver variable.

       if(driver==null) {
          WebDriverManager.chromedriver().setup();
          driver = new ChromeDriver();
          driver.get("https://www.zoho.com/");
          driver.manage().window().maximize();
          driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        }

Actually now i have given if(driver==null),even before giving that,i got the NPE @ driver.get("https://www.zoho.com/"); – vaishnavi A.N. Jul 19 '20 at 07:13
So are your still getting NPE with this code? If so, then webdrivermanager is not finding the installed chrome installed in your system. – Abhinaba Chakraborty Jul 19 '20 at 07:15
I have assigned the ChromeDriver to the driver variable,right?is it not assigned? – vaishnavi A.N. Jul 19 '20 at 07:19
No, This line `WebDriverManager.chromedriver().setup()` doesnt assign the driver variable. Please check my code. – Abhinaba Chakraborty Jul 19 '20 at 07:27
@vaishnaviA.N. any updates ? Did it work for you? – Abhinaba Chakraborty Jul 19 '20 at 08:06
yeah perfect ! Thank you very much @Abhinaba Chakraborty, I was thinking what was going wrong with my code,Thank you again... – vaishnavi A.N. Jul 19 '20 at 09:26
