Second class is throwing Null Pointer exception for TestNG

I've created different classes for each webpage using TestNG. My first class is working fine but the second class is throwing Null Pointer Exception. The same script if I combine in only one class It's working without any issues.
Below is my baseclass
package Test;
import org.testng.annotations.Test;
import Pages.FM_login;
import org.testng.annotations.BeforeTest;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.AfterTest;
public class Baseclass {
WebDriver driver;
FM_login objLogin;
#BeforeTest
public void setup() {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\****\\Downloads\\chromedriver.exe");
String url = "http://vatlookup.cloudfront.net";
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get(url);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
String Title = driver.getTitle();
System.out.println(Title);
System.out.println("Application Launch successful");
// Accept the cookie policy
driver.findElement(By.xpath("//a[#class='cc-btn cc-allow']")).click();
}
#Test
public void Login() {
objLogin = new FM_login(driver);
objLogin.GoToLoginScreen();
objLogin.loginToFleetMatch("abc", "123");
System.out.println("Login Successful");
}
#AfterTest(enabled=false)
public void teardown() {
driver.close();
}
This is another class
package Test;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;
import Pages.FM_Profile;
public class Profile {
WebDriver driver;
FM_Profile objProfile;
#Test
public void Skip_Tutorial() {
objProfile = new FM_Profile(driver);
driver.getCurrentUrl();
objProfile.SkipTutorial();
}
#Test(enabled=false)
public void edit_profile() {
objProfile.edit_profile();
}
}
below is the page object for a second class
package Pages;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class FM_Profile {
WebDriver driver;
By company_name = By.xpath("//p[#id='company-name']");
By plan_details = By.xpath("//p[#id='current-plan']");
By End_tour = By.xpath("//button[#class='driver-close-btn']");
By edit_profile = By.xpath("//span[contains(text(),'Edit')]");
By Description = By.xpath("//textarea[#id='mat-input-10']");
By Upload_image = By.xpath("//div[#class='upload-btn continental-book ng-star-inserted']");
By Save_profile = By.xpath("//button[#class='save-btn continental-book mat-stroked-button mat-button-base mat-primary editMode cdk-focused cdk-mouse-focused']");
public FM_Profile(WebDriver driver) {
this.driver = driver;
}
public void SkipTutorial() {
driver.findElement(End_tour).click();
}
after executing it's showing java.lang.NullPointerException for second class

In your Profile class the driver object is not initialized. The driver object that you are initializing is in BaseClass and instance of that class. You need to initialize driver object in Profile class as well

WebDriver is never initialised.
WebDriver driver = new WebDriver();

Null pointer exception serenity behave root package

I am trying to run a simple bdd test using behave and serenity but i am getting a initialization error. It seems as though there is a package class which is null but i cannot figure out which one or is there something wrong with way i am initialising my code.
I have been serenity bdd documentation online
https://serenity-bdd.github.io/theserenitybook/latest/jbehave.html
directory tree
new output
Appreciate the help :)

Selenium/Cucumber not seeing step definitions after folder migration

I recently cleaned up my dependencies folder structure and think I might have misplaced something, but my problem is an instantiation issue that doesn't make sense as it seems I have my ducks in a row on the cucumber side. Here is the stack trace:

Here is my cucumber runner that sets up the feature files, but never executes the glue command. My package cucumber.feature contains my step definition file LoginandMeetingCreation.java file:
package cucumberInitialization;
import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
#RunWith(Cucumber.class)
#CucumberOptions(
plugin = {"pretty" , "json:target/cucumber.json"},
features = {"src/cucumber/"},
monochrome = true,
glue = {"cucumber.feature"}
)
public class cucumberRunner {
}
Feature file with steps:
Feature: Create a meeting and fill in the necessary text fields
Scenario: As a user, login and create a meeting
Given I navigated to the site
When I login and select an org
Then Create a meeting
And finally my step definitions:
package cucumber.feature;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;

public class LoginandMeetingCreation {
WebDriver chromeDriver = null;
WebDriver ieDriver = null;
//open IE and Chrome browsers and go to Website
#Given("^I navigated to the site$")
public void navigateToWebsite() throws Throwable{
throw new PendingException();
}
//login users
#When("^I login and select an org$")
public void userLogin() throws Throwable{
throw new PendingException();
}
#Then("^Create a meeting$")
public void meetingCreation() throws Throwable{
throw new PendingException();
}
}
Any advice?

Thanks GalexMES.
You were right, I had forgotten I had deleted a bulk amount and it dawned on me I was creating an object that cannot accept a null value. When I had written WebDriverWait wait = new WebDriverWait(ieDriver, 5); ieDriver was null, which causes the NPE. Once I create the ieDriver object from a non null value the expected behavior is executed.

Selenium java.lang.NullPointerException with PageFactory

I'm trying to get a hang of PageFactory POM, however something is not working and I can not understand what is wrong.
This is my first POM class for Home Page:
package PageFactory;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
public class Home_Page_POF {
public WebDriver driver;
#FindBy(css = "div#header-profile a#header-profile-toggle")
public WebElement profileToggleButton;
#FindBy(css = "form#loginUserdataForm div.footer div.add-footer a.btn.btn-link.linkicon")
public WebElement newRegistrationButton;
public Home_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
}
}
This is the second POM class for the Reg. page
package PageFactory;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.Select;
public class Registration_Page_POF {
public WebDriver driver;
//Personal details WebElements
#FindBy(css = "form#personalDetailsForm div.profile.pe div.profile-block.simple.first fieldset#pefield-title select#pesalutation")
public WebElement titleDropdown;
public Select titleSelect = new Select(titleDropdown);
public Registration_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
}
}
And this is the test case:
package Tests;
import PageFactory.Home_Page_POF;
import PageFactory.Registration_Page_POF;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.io.TemporaryFilesystem;
import org.openqa.selenium.support.ui.Select;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
import java.util.concurrent.TimeUnit;
public class Test_POF {
public WebDriver driver;
Home_Page_POF objHomePage;
Registration_Page_POF objRegPage;
#BeforeClass
public void browserSetUp() {
System.setProperty("webdriver.chrome.driver", "D:/Install/selenium-2.53.0/drivers/chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.navigate().to("http://www.lufthansa.com/");
}
#AfterClass
public void broserCleanUp() {
if (driver != null) {
TemporaryFilesystem.getDefaultTmpFS().deleteTemporaryFiles();
driver.close();
driver.quit();
}
}
#Test
public void Test0001() {
objHomePage = new Home_Page_POF(driver);
objHomePage.profileToggleButton.click();
objHomePage.newRegistrationButton.click();
objRegPage = new Registration_Page_POF(driver);
Select titleSelect = new Select(objRegPage.titleDropdown);
titleSelect.selectByVisibleText("Mr.");
}
}
So the HomePage objects are working fine, I click on two buttons and proceed to registration page.
After that I want to select a value from dropdown, but it gives me NullPointerException:

The Problem is you are initializing the varaible titleSelect in class itself. Just Initialize inside constructor or after finding the element;
public class Registration_Page_POF {
public WebDriver driver;
//Personal details WebElements
#FindBy(css = "form#personalDetailsForm div.profile.pe div.profile-block.simple.first fieldset#pefield-title select#pesalutation")
public WebElement titleDropdown;
public Select titleSelect; //Dont initialize here
public Registration_Page_POF(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
titleSelect = new Select(titleDropdown);//initialize here
}
}

Cannot instantiate class

iam facing a problem i have written a method navback, which i need to use regularily to navigate back. when iam running it is throwing a error.
below is the Code.

public class Flipkart {
public static WebDriver driver;
Actions action = new Actions(driver);
//String ddd;
// public Example2() {

// }
#BeforeClass
public void beforeClass()
{
driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(30000, TimeUnit.MILLISECONDS);
}
#Test
public void mailSend() throws InterruptedException
{
driver.get("https://www.flipkart.com/");
driver.manage().window().maximize();
navback();

You don't initialize driver, so it is null, but you pass it to Actions.
public static WebDriver driver;
Actions action = new Actions(driver);
That throws a NullPointerException.
Caused by: java.lang.NullPointerException
at org.openqa.selenium.interactions.Actions.<init>(Actions.java:41)
Initialize driver.
Note the lifecycle. Before JUnit runs your #BeforeClass or #Before methods, it has to create the Flipkart instance. The instance field initialization expression runs at that point.
Rethink your design. Initialize action after driver has been initialized.
