说明：  编写一个Java应用程序，实现如下功能： 　　1）判断两个字符串是否相同，s1=”you are a student”，s2=”how are you”； 　　2）判断字符串”22030219851022024”的前缀、后缀是否和某个字符串”220302”相同； 　　3）按字典顺序比较两个字符串”你”和”我”的大小关系； 　　4）将数字型字符串”100”和”123.678”转换为数字； 　　5）将字符串”FEDCBA”存放到数组中，调用for循环读出数组数据显示在屏幕上。
(Write a Java application, to achieve the following functions: 1) to determine whether the same two strings, s1 = " you are a student" , s2 = " how are you" 2) to determine the string " 22030219851022024" prefix, suffix whether and a string " 220,302" the same 3) according to the dictionary in order to compare two strings " you" and " me" the size of the relationship 4) the numeric string " 100" and " 123.678" conversion to digital 5 ) will be the string " FEDCBA" store to the array, calling for loop to read out an array of data displayed on the screen.)
