Multiple browser windows opening automatically when one class is called in another class - selenium

Question

I have created a class in which I am creating all the methods I require for my test automation. Issue which I am facing is that when I run main class, it works fine. But when I call that class in other class it opens 2 browser windows. The test is performed on 1 and other remains ideal. Also when I use close() or quit() method for #After, it closes the ideal window not the one which I am working on.
Below is my code snippet for ref.
Main class
public class ProjectManagement{
WebDriver driver = new FirefoxDriver();
public void navigateCreate(String uid, String pass) throws Throwable {
driver.manage().window().maximize();
driver.get(baseurl);
driver.findElement(By.id("Email")).sendKeys(uid);
driver.findElement(By.id("Password")).sendKeys(pass);
driver.findElement(By.id("loginBtn")).click();
driver.findElement(By.linkText("Projects")).click();
driver.findElement(By.linkText("Create New Project")).click();
}
}
Test Class
public class NewTest extends ProjectManagement{
ProjectManagement project1 = new ProjectManagement();
#Test
public void createPro() throws Throwable {
project1.navigateCreate(UId,Password);
}
#AfterTest
public void afterTest() {
driver.quit();
}
}

If you are extending ProjectManagement, you don't need to instantiate it on the sub-class. By doing so, you're effectively creating two instances of the class and, as such, two instances of WebDriver (which in turn generates two browser windows).
So, remove the following:
ProjectManagement project1 = new ProjectManagement();
And change your createPro() method to:
#Test
public void createPro() throws Throwable {
navigateCreate(UId,Password);
}
