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:

动画片命运石之门第二季全集又名命运石之门0，是根据同名游戏改编的TV动画《命运石之门》的续作。动画第二季背景故事讲述的是2010年7月28日，“未来道具研究所”社团的两人，冈部伦太郎和椎名真由里去秋叶原广播会馆参加中钵博士的时间旅行理论发表会，见到了年仅18岁就在科学杂志上发表学术论文的天才少女牧濑红莉栖。发表会结束不久后，在会馆8楼深处，冈部发现了倒在血泊中的红莉栖。惊慌失措的他带着真由里立刻离开会馆，给社团另一成员桥田至发送一条电子邮件告知这一事件。然而发送后的瞬间，冈部愕然发现街道人群消失，广播会馆及周围早已因不明人造卫星坠落缘故被封锁，没有人记得他所经历的事件。
巨魔国叛乱，莱拉被送到人界
北京时间9月25日，ABC电视台重磅医务剧将以两小时特别篇回到我们的视线，上一季结尾留下的Izzie和George的去留问题将在回归篇中一一解答。感谢KatherineHeigl的直言，我们已经大概得知剧中这两位主要人物的命运。Izzie将会幸存下来，而George将告别观众。而且因为TRKnight的合同问题，George可能将不会再以新镜头出现在第六季中，开篇也仅仅将以一具棺材代替他的存在。ABC电视台也确认George的扮演者TR Knight将不会成为第六季的常规演员，与之相反的是扮演儿科医生的Arizona Robbins的JessicaCapshaw将有幸成为第六季的常规演员。可以预见，其与剧中另一主要角色Callie的同性恋情的戏份也将加长。

Comparing the similarities and differences between the garrison forces of our army at position 169 and position 142, It will be found that there are a large number of people in position 169 (a reinforced platoon with a total of 45 people and equipped with recoilless rifles and other infantry powerful assault weapons, after being reinforced by the chemical defense squad, although the total number of combat personnel was reduced by 2 people, two 74-type flamethrowers were added, and the melee and assault capabilities were actually strengthened), The firepower is relatively strong, When the Vietnamese troops attacked here, they sent out strong defensive humanoid monsters. However, the number of people in position 142 is relatively small (only the "15 warriors" led by Li Haixin, And only equipped with rocket launchers, Without recoilless guns and flamethrowers, However, there are simple minefields with anti-infantry mines. This is better than at position 169, If a minefield is also deployed at position 169, Although it is not possible to completely kill the humanoid monster at one time, But it can certainly play a significant blocking role, To provide favorable conditions for the main position to carry forward its firepower and carry out annihilating shooting), The firepower is relatively weak, When the Vietnamese army attacked here, it sent out such small targets. Fast, unidentified creatures like "dogs", To sum up, the defense-strong humanoid monster stormed the powerful position 169, It should not be a coincidence that the Vietnamese army has certain tactical considerations when using "living biological weapons" to attack positions more suitable for its own characteristics with different "living biological weapons" instead of simply throwing themselves into the battlefield at will.
