Question

好的，所以我正在编写一个程序，将文件从我的usb传输到计算机（所以我可以快速设置东西，以便我在星期一做的事情）并且我试图让它在桌面上制作一个快捷方式，这样你就不会必须进入已传输文件的源文件夹，以便在退出时再次启动程序。继承我的代码，标题是我得到的错误。

    String desktop = System.getProperty("user.home") + "/Desktop";
    File srcFolder = new File(usb + "/Teamspeak 3");
    File destFolder = new File(desktop + "/TS3");

    //make sure source exists
    if(!srcFolder.exists()){

       System.out.println("Directory does not exist.");
       //just exit
       System.exit(0);

    }else{

String line =  "-shortcut -t c:/ocuments and Settings/%username%/Desktop/TS3/ts3client_win32.exe" "-n Teamspeak 3.lnk";

这条线似乎格格不入。你有两个没有+的字符串。

转义序列无效（有效转义序列为\ b \ t \ n \ f \ r \“\'\\ \）
