java - 创建排除引号内容的空格分隔列表

Question

我如何在java中创建一个列表，从foo bar“lorem ipsum”的输入打印[foo,bar,“lorem ipsum”]谢谢!

Answer 1

我想通了，有两个列表可以找到值然后将它们合并。

            String message = "foo bar "lorem ipsum";
            // Getting the value of the quotes
            List<String> quotes = new ArrayList<String>();
            Matcher m = Pattern.compile("\\\"([^\\\"]*)\\\"")
                    .matcher(message);
            while (m.find()) {
                quotes.add(m.group());
            }
            // Removing quotes from string
            message = message.replaceAll("\\\"([^\\\"]*)\\\"", "");
            List<String> space = Arrays.asList(message.split("\\s* \\s*"));
            // Merging the lists
            List<String> newList = Stream.concat(space.stream(), quotes.stream())
                    .collect(Collectors.toList());
            // Printing
            System.out.println(newList);
