你写的真好,昨晚我看了好久
这是我参考总结的关键路径解法,您的关键路径部分只有说明,总觉得可以再补充点。

大佬写得真好,有没有汇编程序设计的总结,复试面试有问答
有向图中,如果 Vi 到 Vj 有路径,且反过来也有路径,则称这两个顶点强连通。
非常感谢大佬辛苦总结出来的计算机基础知识大全~
关于“丢失更新”,似乎前两个隔离级别并不会解决上文所提到的逻辑上的丢失更新问题。
例如,在其他博客中所查到,“READ UNCOMMITTED 读取未提交”采用“一级封锁协议,只对修改数据的并发操作做限制”,那么是无法解决“丢失更新”问题。
由于手边没有书籍,无法找到更权威的解释,望作者解惑!!
“对于 str1 来说,new String("hello") 分两步走:首先,"hello" 属于字符串字面量,因此编译时期会在 String Pool 中查找有没有值为 "hello" 的引用,如果没找到,就在字符串常量池中开辟地址空间创建一个字符串对象,指向这个 "hello" 字符串字面量;
然后,使用 new的方式又会在堆中创建一个字符串对象。”
“对于 str3 来说,str1.intern() 会先在 String Pool 中查看是否已经存在一个字符串和 str1 的值相等,没有,于是,在 String Pool 中添加了一个新的值和 str1 相等的字符串,并返回这个新字符串的引用。”
这两段话不是自相矛盾吗?str1.intern( )根本不会起作用,因为str1在 new( )的时候已经把"Hello"添加到常量池了。
