java排队

排序就排序呗。

数据量不大，排序花不了多少时间的。

其实既然你要求的“要求服务时间”是固定的，那么优先级就等于1+等待时间/要求服务时间。也就是优先级和顷凳等待时间是线性关系。而且，刚服务的那人等待时间被清0了，一定是最小的，所雀启旅以这样：每处理一个业务，检查他时间到没，到了出队列，没到排队尾，因为他的等待时间是0，必然最小，而刚才没有做业务的旁弯，等待时间都同等增加的，所以他们的优先级次序没变，直接把下个拿过来办就行了

给你说个思路

1. 按行读文件, 每猛李者一行split('\\s'扰逗),然后只要id 这个String

2. 然后取id后的十六进制数

3. 将枝薯此行和这一整行(value)和它对应的十六进制数(key)写入一个map

4. 对十六进制树进行排序

5. get by key

6. 输出
