1．文件和目录管理，使用java.io.File类编程，完成如下功能： （1）输入文件名称 （2）判断该文件名称是否存在 （3）若文件存在，判断是文件还是目录 （4）若是文件则输出文件的各种属性 （5）若是目录则输出其中包含的所有文件的名称 2．二进制文件的读写操作，用InputStream和OutputStream及其子类，设计并实现一个可以完成文件复制操作的程序。 3．文本文件的读写操作，编写一个文本文件分析程序，读入一个英文文本文件，统计其中单词、数字、标点符号等元素出现的次数，并记录单词总数。提示：对文件的分析可以使用StreamTokenizer类。 4．异常处理程序的编写，在上述三个程序中应用异常处理方法增加程序的错误处理能力。-1.
