正则表达式之以空格分割字符串但忽略引号中的内容

目标串: "aaa bbb "cc dd" eee fff"
期望结果:

aaa
bbb
"cc dd"
eee
fff

具体实现:

    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 list = new ArrayList<>();
        while (matcher.find()) {
            list.add(matcher.group());
        }
        for (String s : list){
            System.out.println(s);
        }
    }
