java.lang.NullPointerException at creating new object line

I'm trying to use TestNG and Page Object for my Selenium test. But it fails with java.lang.NullPointerException error at a line where I'm creating new object of my Page Object Class.

public class TestTitle {

    @Test
    public void scenario1() {

        System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
        WebDriver driver=new ChromeDriver();
        FirstPage fp = new FirstPage(driver);
        driver.get("https://www.google.com/");
        fp.element.click();
    }
}


public class FirstPage {

    WebDriver driver;
    public FirstPage (WebDriver driver) {
        this.driver = driver;
    }

    public WebElement element = driver.findElement(By.id("hptl"));

}




FAILED: scenario1
java.lang.NullPointerException
at Pages.FirstPage.<init>(FirstPage.java:14)
at Test.TestTitle.scenario1(TestTitle.java:15)

FirstPage.java:14 is public WebElement element = driver.findElement(By.id("hptl")); TestTitle.java:15 is FirstPage fp = new FirstPage(driver);
