queue implementation in java

Data Structure Java Implementation -- queue's "wonderful" second-priority queue, java queuePreface In many cases, some data storage not only requires FIFO, but also sorting based on the priority of the data, that is, the priority must first go out, the priority of the same FIFO, in this case, the priority
