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();

I am trying to automate using selenium webdriver, testng and page factory. But I am facing null pointer exception

import org.openqa.selenium.support.PageFactory;

loginpage Class
public class loginpage {

public loginpage(WebDriver driver)
{

PageFactory.initElements(driver, this);
}
#FindBy(xpath="//*[#id=\"txtUserId\"]")
WebElement loginid;
#FindBy(xpath="//*[#id=\"txtPassword\"]")

}
public WebElement userPassword(){

}
}
Place_Order Class
public class Place_Order extends Browser{
WebDriver driver;
#Test
public void Place_Reservation() throws Exception
{
loginpage raku = PageFactory.initElements(driver, loginpage.class);
raku.userid().sendKeys("fp-ifttest");
raku.userPassword().sendKeys("ift");
}
}

Modify the code in the test class, as you are not initializing the driver correctly and also call the constructor of the pageobject instead.
#Test
public void Place_Reservation() throws Exception
{
**loginpage raku = new loginpage(Browser.driver);**
raku.userid().sendKeys("fp-ifttest");
raku.userPassword().sendKeys("ift");
}
Also try to follow Java naming standards like using capitals as starting for class names etc.

IntelliJ Error: java.lang.NullPointerException

I'm new in Selenium, I use IntelliJ, Selenium WebDriver, Junit. My problem is
java.lang.NullPointerException . These are my pages in project.
This is HomePage page:
package PageObjectPage;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

super(driver);
}
public MyAccount clickOnMyAccount(){
//Click on My Account
button_my_accout.click();
return PageFactory.initElements(getDriver(), MyAccount.class);

In your AccountTest class you are declaring WebDrive driver; again which setting to driver=null, this cause HomePage driver to be null; Also you do not need getter for webDriver. This should work just fine
public class AccountTest extends TestBase {
#Test
public void shouldLogIn() {
HomePage onHomePage = PageFactory.initElements(driver, HomePage.class);
System.out.println("Step 1 ");
MyAccount onMyAccount = onHomePage.clickOnMyAccount();
System.out.println("Step 2");
LogInResultPage onResultPage = onMyAccount.LogIn().submitForm();
System.out.println("Step 3");
wait(2000);
Assert.assertTrue(onResultPage.getMessage().contains("ERROR"));
}
public void wait(int seconds){
try {
Thread.sleep(2000);

Can not Instantiate Class Exception TestNG

I am getting following error when I run code in Selenium and Java using TestNG. On multiple blogs/sites it is mentioned to clean the project and so I did Project->Clean but still it is throwing me this error. Can some one please point me what is wrong in this code? Thanks.

I have made changes to the above code now its working fine...
The issue was due to driver instance scope it was defined inside a method..
package firsttestngpackage;
//import org.testng.annotations.Test;
//import org.openqa.selenium.*;
import org.testng.Assert;
import org.testng.annotations.*;
//import org.testng.asserts.*;
//import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class FirstTestNGFile {
public WebDriver driver1 ;
#BeforeSuite
public void SetBrowser(){
System.setProperty("webdriver.chrome.driver", "/home/vicky/Documents/Jars/chromedriver");
driver1= new ChromeDriver();
}
public String baseurl = "http://newtours.demoaut.com/";
public String ExpTitle = "Welcome: Mercury Tours";
#Test
public void CheckPageTitle() {
driver1.get(baseurl);
String ActTitle = driver1.getTitle();
Assert.assertEquals(ActTitle, ExpTitle);
driver1.quit();
}
}

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.
package Examples;
import java.util.concurrent.TimeUnit;
//import org.junit.BeforeClass;
import org.testng.annotations.BeforeClass;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;
import org.testng.annotations.AfterClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class Flipkart {
public static WebDriver driver;
Actions action = new Actions(driver);
//String ddd;
// public Example2() {
// super();
// }
#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();
driver.findElement(By.xpath("/html/body/div/div/div[2]/div/div/ul/li/div/div[2]/div/ul/li[2]/a")).click();
driver.navigate().back();
navback();
driver.findElement(By.xpath("/html/body/div/div/div[2]/div/div/ul/li/div/div[2]/div/ul/li[3]/a")).click();
driver.navigate().back();
driver.navigate().refresh();
}
public void navback()
{
WebElement we = driver.findElement(By.xpath("//html/body/div/div/div[2]/div/div/ul/li/a/span"));
action.moveToElement(we).build().perform();
}
#AfterClass
public void tear()
{
// driver.quit();
}
}
Below is the Error.

Please some one help me, iam not able to proceed further.
Thanks

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

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.
