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.
