java为什么这段代码会抛出我项目中随机其他代码的输出？我该怎么解决这个问题？

Question

我是Java新手，可能把代码搞砸了。但这里怎么了？我正在尝试为我必须测试的主页中的元素创建对象

   package pageObjects;

      import org.openqa.selenium.By;
      import org.openqa.selenium.WebDriver;
      import org.openqa.selenium.WebElement;

public class HomePage {

private static WebElement element;

public static void main(String args[], WebDriver driver){

    HomePage hp = new HomePage();
    hp.SignInButton(driver);
    hp.ImageButton(driver);
    System.out.println("Yup");
}

public WebElement SignInButton(WebDriver driver){

    element = driver.findElement(By.linkText("Sign In"));
    System.out.println("Yeua");
    return element;

}

public WebElement ImageButton(WebDriver driver){

    return element = driver.findElement(By.linkText("Images"));

}

  }
