java - 自动转义引号

Question

我有一个类似于以下内容的文本文件:

word("word1");
word("word2");
word("word3");
etc

(从网站复制)

我想编写一个java程序来获取每个单词(word1、word2等)并将其放入String[]中。输出将是

my_list = {"word1", "word2" etc};

我想将原始输入放在括号之间以使其成为字符串，然后对其进行处理，但问题是我需要手动转义文件中的每个“”。

如何解决这个问题？

你的意思是这样的:

try {
        String text = "word(\"word1\");\n"
                + "word(\"word2\");\n"
                + "word(\"word3\");\n"
                + "etc";
        Pattern pattern = Pattern.compile("\".*?\"");
        Matcher matcher = pattern.matcher(text);
        ArrayList<String> list = new ArrayList<>();
        while (matcher.find()) {
            list.add(matcher.group(0));
        }
        StringBuilder out = new StringBuilder("my_list = {");
        for (Iterator<String> iterator = list.iterator(); iterator.hasNext();) {
                out.append(iterator.next());
            if(iterator.hasNext())
                out.append(", ");
        }
        out.append("};");
        JOptionPane.showMessageDialog(null, out.toString());
    } catch (PatternSyntaxException ex) {
        // Syntax error in the regular expression
    }
