Firefox driver is based on marionettestarting with Selenium 3.0. Unlike, 2.x versions, it requires an external executable file. You should add it to your path. For more information, you should have a look at https://github.com/mozilla/geckodriver.
Firefox 驱动程序基于从 Selenium 3.0 开始的marionette。与 2.x 版本不同，它需要一个外部可执行文件。您应该将其添加到您的路径中。有关更多信息，您应该查看https://github.com/mozilla/geckodriver。

Download the lastest version for geckoDriver herethen set a System property called "webdriver.gecko.driver" and put on it the path to your geckoDriver executable path
System.setProperty("webdriver.gecko.driver", "<path to your gecko driver executable>");
在此处下载 geckoDriver 的最新版本，然后设置一个名为“webdriver.gecko.driver”的系统属性并将其放在 geckoDriver 可执行路径的路径上
System.setProperty("webdriver.gecko.driver", "<path to your gecko driver executable>");

You are using latest version of Selenium WebDriveri.e. Selenium 3.x, this version of webdriver doesn't support direct firefox launch. You have to set the SystemPropertyfor webdriver.gecko.driver.
您使用的是最新版本的Selenium WebDriverie Selenium 3.x，此版本的 webdriver 不支持直接启动 firefox。您必须设置SystemPropertyfor webdriver.gecko.driver。
Replace the Code:-
替换代码：-
WebDriver driver;
driver =new FirefoxDriver();
With This code:-
使用此代码：-
WebDriver driver;
System.setProperty("webdriver.gecko.driver", "<Path to your WebDriver>");
driver =new FirefoxDriver();
