User class unified interface, User1 and User2 are different objects respectively, and they are related. If the mediator mode is not adopted, the two need to hold references to each other, so the coupling degree between the two is very high. In order to decouple, the Mediator class is introduced to provide unified interface, and MyMediator is its implementation class, which holds instances of User1 and User2 to control User1 and User2. In this way, User1 and User2 objects are independent of each other. They only need to maintain a good relationship with the Mediator, and the rest is maintained by the MyMediator class! Basic implementation:L a good place to climb mountains and exercise, you can even find a tea shop on the way to have tea or eat snacks at Tianhu Lake after climbing the top.I have also seen it spray on cars. The fuel burns to extinguish the flame for more than five minutes. When it finally went out, the whole car head was burned by more than half. Although I don't know the specific figure of the temperature, the comrades in the chemical defense class said it was at least 1300-1500 degrees Celsius, so I thought at that time, even the steel plate could melt into the flame of molten iron in a few minutes. It was not a piece of cake to burn this insect. Even if you are much bigger than the average wasp, may there be steel plates that are resistant to burning? After being ignited by the flame, it should be burned to ashes in an instant. But the result was not what I thought. After being ignited, the big wasp was quite resistant to burning. Actually flying around in the air for more than ten seconds before being burned, the air disintegrated and died. But this has become a good thing, It is precisely because it will burn to death for a while. So flying in the air with flames all over it must be either because of the sharp pain, Either they lost their direction because of something else, Anyway, it is flying around in the air, As a result, they hit many of their peers in the process of flying around. Then it ignited the same kind that was hit, If the ignited kind bumps into each other again, To ignite another kind, It just went through a couple of cycles, Most of the big wasps were set on fire, That will burn quickly. The sky is full of the sound of "crackling" burning meat, and there is a smell of barbecue burnt. The black corpses of wasps that have been burned apart and fallen and the corpses of wasps that have been smashed by bullets are piled up most. One foot is thick enough to reach the knee.
