有趣的是，这只发生在我程序的主方法内部，而不是粘贴到主类外部

为什么这个长字符串在粘贴到main方法中时变得完全不可见，我如何将这个字符串粘贴到我的程序中

Answer 1

我想在这种情况下，读一本书会更明智。包含所需数据的txt文件，然后将其写入字符串。我只是好奇为什么Eclipse不接受长字符串到Java程序中。无论如何：

        String myCurrentDir = System.getProperty("user.dir");
        String textDir = myCurrentDir + "\\" + MyClass.class.getName().toString() + ".txt";
        // System.out.println(textDir);

        File f = new File(textDir);
        FileInputStream fin = new FileInputStream(f);
        byte[] buffer = new byte[(int) f.length()];
        new DataInputStream(fin).readFully(buffer);
        fin.close();
        String commaString = new String(buffer, "UTF-8");
