正則表達式之以空格分割字符串但忽略引號中的內容

目標串: "aaa bbb "cc dd" eee fff"
期望結果:

aaa
bbb
"cc dd"
eee
fff

具體實現:

 

    private static final Pattern PATTERN = Pattern.compile("\"([^\"]*?)\"|(\\S+)");

    public static void main(String[] args) {
        String str = "aaa bbb \"cc dd\" eee fff";
        Matcher matcher = PATTERN.matcher(str);
        List<String> list = new ArrayList<>();
        while (matcher.find()) {
            list.add(matcher.group());
        }
        for (String s : list){
            System.out.println(s);
        }
    }
