题目描述：

大侦探福尔摩斯接到一张奇怪的字条：“我们约会吧！ 3485djDkxh4hhGE 2984akDfkkkkggEdsb s&hgsfdk
d&Hyscvnm”。大侦探很快就明白了，字条上奇怪的乱码实际上就是约会的时间“星期四 14:04”，因为前面两字符串中第1对相同的大写英文字母（大小写有区分）是第4个字母’D’，代表星期四；第2对相同的字符是’E’，那是第5个英文字母，代表一天里的第14个钟头（于是一天的0点到23点由数字0到9、以及大写字母A到N表示）；后面两字符串第1对相同的英文字母’s’出现在第4个位置（从0开始计数）上，代表第4分钟。现给定两对字符串，请帮助福尔摩斯解码得到约会的时间。

Java代码：
