Recieving a java.lang.NullPointerException when running my project in Page object model with selenium webdriver

I have an issue when creating page object model with selenium webdriver and using testng to create my tests. I Instasiated the webdriver in my web_elements.java page and run my tests in Testing1.java on both these classes I have added the webdriver. But when I run the test I get an error.

web_element.java - page

package Pages;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.WebDriverWait;

import java.util.concurrent.TimeUnit;

public class web_Elements {
private final WebDriverWait wait;
WebDriver driver;


public void LoginTest() throws InterruptedException {
    driver.findElement(By.xpath("//body[@class='ng-scope']/div[@class='ng- scope']/div[@class='container-fluid ng-scope']/div[@class='ng-scope']//button[.='Customer Login']")).click();

}

public void SelectYourName() {
    driver.findElement(By.cssSelector("#userSelect > option:nth-child(3)")).click();
}


public web_Elements(WebDriver driver) {
    this.driver = driver;
    long timeOutInSeconds = 10; // just an arbitrary value example
    this.wait = new WebDriverWait(driver, timeOutInSeconds);

    // the rest of your constructor as in the original code
    driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
    driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);


}}

Testing1.java - page

package Test_Cases;

import Pages.web_Elements;
import Utilities.DriverFactory;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;



public class Testing1 {


public WebDriver driver;
web_Elements PageTesting;

@BeforeClass
public void Initialize_driver() throws InterruptedException {
    ///Initialize diver
    System.setProperty("webdriver.chrome.driver", 
   "C:\\Users\\rassools\\Documents\\ChromeD\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("http://www.way2automation.com/angularjs-protractor/banking/#/login");
    driver.manage().window().maximize();


}

@Test(priority = 0)
public void other() throws InterruptedException {
    PageTesting = new web_Elements(driver);
    PageTesting.LoginTest();
    PageTesting.SelectYourName();

}


public void wait(int seconds) {
    try {
        Thread.sleep(2000);
    } catch (final InterruptedException e) {
        e.printStackTrace();

    }
}
}
