How to implement set property in testng

Question

    import org.testng.annotations.*;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class redc {
    public static WebDriver driver=null;
    public static  void startdriver()
    {
    String key="webdriver.gecko.driver";
    String path="C:\\selenium3\\geckodriver\\geckodriver.exe";
    System.setProperty(key,path);
    driver = new FirefoxDriver();
        }
    @BeforeMethod
    public void call()
    {


    }
    @Test
    public void t1()
    {
        driver.get("https://www.dynamiclevels.com/");
    }

I am trying to run this code but constantly getting error

FAILED: t1 java.lang.NullPointerException at datac.redc.t1(redc.java:25) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

Please help me correct the code. If possible rewrite it in in a way it would work. I am sure i am making same silly mistake i cant catch. :(

@BeforeTest
public void setup() {
    String key= "webdriver.gecko.driver";
    String path= "C:\\selenium3\\geckodriver\\geckodriver.exe";
    System.setProperty(key, path);
    driver = new FirefoxDriver();
}

and remove static from WebDriver:

private WebDriver driver;
