I have created 2 classes in 2 packages under one project and calling one method of class A into class B by creating object of class but it is giving me null pointer exception below is the code can any one help on this

package Login;

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.AfterTest; import org.testng.annotations.BeforeSuite; import org.testng.annotations.BeforeTest; import org.testng.annotations.Test;

import Repository.Objects;

// import Repository.Objects;

public class Loginasa {

public static  WebDriver driver;
 String baseUrl;
    
 @BeforeSuite
 public void setUp() throws Exception 
 {
    System.setProperty("webdriver.chrome.driver","E:\\chromedriver_win32\\chromedriver.exe");
    driver =new ChromeDriver();
    baseUrl= "http://10.7.30.135:9090/xGLinear/login.html";
    driver.get(baseUrl);
    driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
 }



@Test 
 public void Newlogin() throws Exception 
 {
 // driver.get(baseUrl);

driver.findElement(By.id(Objects.Username)).clear();
driver.findElement(By.id(Objects.Username)).sendKeys("ASA");
driver.findElement(By.id(Objects.Password)).clear();
driver.findElement(By.id(Objects.Password)).sendKeys("Abcd1234");
driver.findElement(By.id(Objects.loginbtn)).click();
Thread.sleep(20000);
 }

@AfterTest
  public void tearDown() throws Exception 
 {
    driver.quit();
    System.out.println("Browser Launch");

}

}

Another is

package Commonmethods;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.testng.annotations.AfterTest; import org.testng.annotations.BeforeTest; import org.testng.annotations.Test;

import Login.Loginasa;

public class CreateOrderline {

public static  WebDriver driver;
String baseUrl;

 @BeforeTest
 public void setUp() throws Exception 
 {
    System.setProperty("webdriver.chrome.driver","E:\\chromedriver_win32\\chromedriver.exe");
    driver =new ChromeDriver();
    baseUrl= "http://10.7.30.135:9090/xGLinear/login.html";
    driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
    
    
 }
 
@Test 
 public void Orderline () throws Exception 
 {
    driver.get(baseUrl);
    Loginasa ASA= new Loginasa();
    System.out.println("Browser Launch");
     ASA.Newlogin();
     
 }
 
     @AfterTest
      public void tearDown() throws Exception 
     {
        driver.quit();
        System.out.println("Browser Launch");
   }
 }

Thanks in advance
