用其他列表中的單獨元素和元素填充java列表的最佳方法是什麼？

Question

我需要創建一個鏈表，並用容器中的「容器」和「元素」填充它。

這是我的代碼：

public List<WebElement> getExpectedElements(){ 
    List<WebElement> list = new LinkedList<WebElement>(Arrays.asList(
      inetConnection, 
      wiredConnection, 
      phonesConnection, 
      usbConnection, 
      wifiConnection 
    )); 
    list.addAll(inetConnection.getExpectedElements()); 
    list.addAll(wiredConnection.getExpectedElements()); 
    list.addAll(phonesConnection.getExpectedElements()); 
    list.addAll(usbConnection.getExpectedElements()); 
    list.addAll(wifiConnection.getExpectedElements()); 
    return list; 
} 

是否有在java中的任何方法，使之更好（更簡潔，乾燥等）？

Answer 1

你至少可以引入一個循環：

List<WebElement> containers = Arrays.asList(inetConnection, 
     wiredConnection, 
     phonesConnection, 
     usbConnection, 
     wifiConnection); 
List<WebElement> list = new LinkedList<WebElement>(containers); 
for (WebElement e : containers) 
    list.addAll(e.getExpectedElements());
