看看你main方法;具體而言，

public static void main(String[] args) { 
    // args[0] should be the path that was requested, in which case you 
    // could use 
    if (args.length > 0) { 
     java.io.File f = new java.io.File(args[0]); 
     if (f != null && f.exists()) { 
      try { 
       System.out.println(f.getCanonicalPath()); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 
}
