什么调用了englishGreeting对象的greet()方法？我很困惑..

编辑

感谢您的回复。我早该发现的！我试图解决另一个查询，即：

在示例程序中 https://gist.github.com/bernii/5697073

代码中

this.wait.until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver webDriver) {
                System.out.println("Searching ...");
                return webDriver.findElement(By.id("resultStats")) != null;
            }
});

什么调用了匿名内部的apply()方法class?

编辑

我现在在一个新问题中提出了我的第二个问题。

Answer 1

EnglishGreeting对象的greet()方法在SpanishGreeting之后调用class

englishGreeting.greet();

更新： apply- 方法是从

调用的

WebDriverWait.until()

Answer 2

在下面显示的代码部分中，创建了 HelloWorld 接口的三个实例：

    HelloWorld englishGreeting = new EnglishGreeting();         
    HelloWorld frenchGreeting = new HelloWorld() {
       //...
    };         
    HelloWorld spanishGreeting = new HelloWorld() {
       // ...
    };

这里对这些实例调用了一些方法：

    englishGreeting.greet();
    frenchGreeting.greetSomeone("Fred");
    spanishGreeting.greet();

法语和西班牙语版本是使用匿名内部 class 创建的。英文版本是根据本地 class 声明 (EnglishGreeting) 创建的。注意：你不会经常看到本地 class 声明，这是一个解释示例。
