D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:

If the ammunition consumption and duration are taken as the criteria, The fighting at position 149 was not as intense as at the previous two positions, But the casualties were the greatest, Investigate its reason, It is precisely because the "living biological weapons" put into the battlefield by the Vietnamese army this time have "flying units", Not only that, It is also accompanied by another type of "living biological weapon" that can operate underground. A special "air-ground coordination" three-dimensional strike has been formed under one day and one place. This made our soldiers in position 142 overwhelmed at that time. During the interview, I had a lot of trouble to find a veteran of that year. His name was Zhang Xiaobo. When recalling the battle, I could see that he was still concerned about the battle, both in tone and manner.

Although it is more worry-free and labor-saving to choose a decoration company for decoration, there will also be drawbacks. Many people will no longer ask about the decoration after handing it over to the decoration company, and it is wrong to wait for acceptance. Because some informal decoration companies will have a series of phenomena such as deliberate charging, project quality problems, slow project progress and excessive project costs. Therefore, even if the decoration company is chosen for decoration, it is necessary to go to the construction site at any time to keep an eye on the work.

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. That scene, I
