How to create an instance of a static class so it can be called from a separate class?
问题
抱歉，这是一个非常基础的问题，但我在这个概念的基础上确实遇到了困难。
我创建了一个公共的静态类来设置浏览器：
private static ThreadLocal<WebDriver> driver = new ThreadLocal<>();public static void setDriver(@NonNull String browserName) {if (browserName.equalsIgnoreCase("chrome")) {WebDriverManager.chromedriver().setup();driver.set(new ChromeDriver());} else if (browserName.equalsIgnoreCase("firefox")) {WebDriverManager.firefoxdriver().setup();driver.set(new FirefoxDriver());}}
在这之下，我使用以下代码获取浏览器：
public static WebDriver getDriver() {return driver.get();}
这在生成单个实例时效果很好，但我需要并行运行，使用多个浏览器实例。
问题是，我不能只是将public static WebDriver getDriver()更改为public WebDriver getDriver()，因为这会影响到后续的所有内容。所以我需要实例化这个类。不幸的是，我尝试过的一切都或多或少地失败了。
在我的项目中，我如何实例化这个类以在其他类中使用？

apologies as this is a really basic problem, but Im really struggling with the basics of this concept.
I have created a public static class to set a browser
private static ThreadLocal<WebDriver> driver = new ThreadLocal<>();public static void setDriver(@NonNull String browserName) {if (browserName.equalsIgnoreCase("chrome")) {WebDriverManager.chromedriver().setup();driver.set(new ChromeDriver());} else if (browserName.equalsIgnoreCase("firefox")) {WebDriverManager.firefoxdriver().setup();driver.set(new FirefoxDriver());}}
below this, I get the browser using
public static driver getDriver() {return driver.get();}
This works fine when generating a single instance, but I need to run this in parallel using multiple instances of the browser.
The problem is, I cant just change public static driver getDriver() to public driver getDriver() because it breaks everything else down the line. So I need to instantiate an instance of this class. Unfortunately, everything I have tried completely fails one way or another.
How can I instantiate this class to use in other classes throughout my project?

你需要重写initialValue()方法。类似于：
private static ThreadLocal<WebDriver> driver = new ThreadLocal<>() {@Override protected WebDriver initialValue() {return getDriver("chrome");}};private static WebDriver getDriver(@NonNull String browserName) {if (browserName.equalsIgnoreCase("chrome")) {WebDriverManager.chromedriver().setup();return new ChromeDriver();} else if (browserName.equalsIgnoreCase("firefox")) {WebDriverManager.firefoxdriver().setup();return new FirefoxDriver();} else {return null;}}
英文:
You need to override the initialValue() method. Something like:
private static ThreadLocal<WebDriver> driver = new ThreadLocal<>() {@Override protected WebDriver initialValue() {return getDriver("chrome");}};private static WebDriver getDriver(@NonNull String browserName) {if (browserName.equalsIgnoreCase("chrome")) {WebDriverManager.chromedriver().setup();return new ChromeDriver();} else if (browserName.equalsIgnoreCase("firefox")) {WebDriverManager.firefoxdriver().setup();return new FirefoxDriver();} else {return null;}}
