This question already has an answer here:

Initialization of an ArrayList in one line 32 answers

Arrays.asList接收省略号（ T... ），所以你不需要数组文字：

myList.addAll(Arrays.asList("Whiskey", "Tango", "Foxtrot"));

myList.addAll(Arrays.asList("Whiskey", "Tango", "Foxtrot"));

因为我不认为你需要字符串数组，所以你可以这样使用

List<String> x = new ArrayList<String>() {{add("Whiskey");add("Tango")add("Foxtrot");}};
