In Inheritance method the Child class not receiving the URL from the Parent class

This is Parent Class to run the ChromeDriver.
package logInCredit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class LogInPage {
public WebDriver driver ;
public void LogInCredit() {
//Open ChromeDriver
WebDriver driver= new ChromeDriver();
driver.get("https://opensource-demo.orangehrmlive.com/");
driver.manage().window().maximize();
System.out.println(driver);
}
}
This Is Child Class which takes the url from Parent Class
package afterLogIn;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.testng.annotations.Test;
import logInCredit.LogInPage;
public class NextLogIn extends LogInPage {
#Test
public void DashboardPage() {
System.out.println("driver is " +driver);
//Admin UserName Enter
WebElement AdminUserName =
driver.findElement(By.xpath("//input[#name='txtUsername']"));
AdminUserName.sendKeys("Admin");
//Admin Password Enter
WebElement AdminPassword =
driver.findElement(By.xpath("//input[#name='txtPassword']"));
AdminPassword.sendKeys("admin123");
//click Login
WebElement LogInButton = driver.findElement(By.xpath("//input[#id='btnLogin']"));
LogInButton.click();
WebElement ClickAdmin = driver.findElement(By.xpath("//*[text()='Admin']"));
ClickAdmin.click();
WebElement ClickPIM = driver.findElement(By.xpath("//*[text()='PIM']"));
ClickPIM.click();
}
}

The Webdriver url from the parent class is not passing to the child class. Is their any Issues with my code. When I run the parent class with main method it navigate the browser to the url but when I call from the child class it not giving the same url.

the class member driver is not instantiated, in the method logInCreated() in the parent class you are using another object reference ( not the class member ).
in the LoginPage add a no arg constructor in wich you instntialize driver
public LoginPage(){ driver = new ChromeDriver(); }
and in the method LogInCredit() delete the line WebDriver driver= new ChromeDriver();

Tried using updated chromedriver but still the problem persist.I am using Eclipse IDE and i imported all the necessary libraries

I too have same issue when I started working. The solution I opted was to first delete all the referenced Selenium files and then download new ones and then assigned them to a folder and added their reference and then it will start working properly.

After import of project, Cannot instantiate class error while running the test configuration

A maven project in eclipse written in Java to automate web application testing.
The project is imported as an existing maven project in Eclipse. The same imported project is working on my co-worker's system while facing the error on another system. Tried to verify other posts and tried to fix the issue, but still no luck.

the problem is located on the command driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);.
Can anyone please tell me why this is happening?

NoSuchfield exception is thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. If this error is happening at the Android driver instantiation, then it could be that some of capabilites you have may not be right. There is no such capability as appium-version - Link. Also device_name is ignored for Android. Try out below capabilities
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME,
"Selendroid");
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "4.3");
capabilities.setCapability(MobileCapabilityType.APP_PACKAGE: "wizzo.mbc.net");
capabilities.setCapability(MobileCapabilityType.APP_ACTIVITY: "wizzo.mbc.net.activities.SplashActivity");

Please help me

The real error is a NullPointerException. I'm going to guess that somewhere in your setup (or in your test), you throw an error, and then you try to access the driver and it is null.
Either put a null check before calling driver.close(), or make sure the driver is never null (I like the first option better).

I received the same error. My issue was that i tried to quite the driver inside #afterMethod. I closed the driver instead of quitting, and the problem got resolved.

I was facing the same problem and to solve it, I updated the chromedriver into my system. Actually one need to check the compatibility of browser and browser driver.
For example, if I was using Chrome 74 so I would update my driver to support Chrome 64.
