现开发一个停车系统,用户根据车位停车1)车主查看现在有无车位(最多100个车位),给车主随机分配一个车位,如果该位置上有车,不能停2)按停车时间收费,3小时以内不收费,3小时以外,每小时2元,最大20元3)车主可以查看自己停车的车位和收费,以及停车的时长4)查看历史停车记录管理员:查看现有的剩余车位查看已停车的车位查看停在车位上的车以及历史缴费Clientpackage com.gem.client;import java.util.Scanner;import...

现开发一个停车系统,用户根据车位停车

1)车主查看现在有无车位(最多100个车位),给车主随机分配一个车位,如果该位置上有车,不能停
2)按停车时间收费,3小时以内不收费,3小时以外,每小时2元,最大20元
3)车主可以查看自己停车的车位和收费,以及停车的时长
4)查看历史停车记录
管理员:
查看现有的剩余车位
查看已停车的车位
查看停在车位上的车以及历史缴费
