如何将驱动程序声明为全局驱动程序？

Question

Here is how I declare firefox driver:

public static WebDriver driver = new FirefoxDriver();

I place the code above outside main and within my class (global)

Here is how I declare chrome driver:

System.setProperty("webdriver.chrome.driver", "/path/xxx/xxx/xx");
WebDriver driver  = new ChromeDriver();

I place the code above in main

Here is the issue:

I want to make the ChromeDriver as a global but I NEED to set the property before doing so. But I place the System.setProperty("xx","xx"); within the main body. Cuz it gives error when placed outside.

Here is a user trying to do the same thing as me. Trying to run different browsers using the same driver : How to run Selenium tests in multiple browsers for cross-browser testing using Java?

The answer is involves declaring the driver in the main body and not as a constant before.

My issue: All functions need driver declaration from before. Calling functions which use driver . If I declare driver in main, I need to continuously pass it as a parameter to all the functions. I do not wish to do that. Here is an example function

 public static void a(){

 driver.findElement(By.id("hi"));

}

How about something like:

class SomeTest {

    static WebDriver driver;

    public static void main(String[] args) {

        System.setProperty("key", "value");
        driver = new ChromeDriver();
    }

    public static void a() {

        driver.findElement(By.id("hi"));

    }
}
