该教程介绍了基本的密码概念以及如何用Java语言实现，并给出了一些示例来说明这些安全机制-The tutorial introduces the basic concept of the password and how to use Java language, and gives some examples to illustrate these security mechanisms

编写一个java应用程序。用户从键盘输入一个1-9999之间的数，程序将判断这个数是几位数，并判断这个数是否回文数。回文数是指将数含有的数字逆序排列后得到的数和原数相同，例如12121,4224,6778776等都是回文数。 1）程序具有判断用户的输入是否为合法整数的功能。对非法输入（例如含有字母）要进行处理。 2）要判断输入数的位数，并输出相关信息。 3）要判断是否回文数。 二、二战期间，英国情报人员获取德军的一机密电报，电报的内容为： bzdz izu sxgzd vs lh ,vpzg woflsh vs vwrh vhlsddlmp glm wrw gzy vsg .gflyz gstfzu bvsg gzsd hdmlp vml lm ,hghzvy wmz hwiry mvvdgvy izd z hzd vivsg ,ltz tmlo tmlO 情报人员已经知道，这段电报的加密方式为： 1. 首先将字符串的顺序颠倒。 2. 字母互换的规律为：A->Z, B-Y, C-X...X->C, Y->B, Z-A a->z, b->y, c-x...x->c, y->b, z->a. 3. 非字母字符保持不变。 请编程帮助情报人员破译这份机密电报。给出注释良好的源程序和程序运行后的结果。 -Write a java application. User keyboard input from a number between 1-9999, the program will determine the number of a few are a few, and to determine whether the number of palindrome number. Palindrome refers to a number of the figure contains a number of reverse order and after a number of the original number of the same, such as the number of 12121,4224,6778776 are palindrome. 1) proced
