      System.out.println(f.getName()+"是可读的吗:"+f.canRead());
      System.out.println(f.getName()+"的长度:"+f.length());
      System.out.println(f.getName()+"的绝对路径:"+f.getAbsolutePath());
      File file = new File("new.txt");
      System.out.println("在当前目录下创建新文件"+file.getName());
      if(!file.exists()) {
