Problem: When debugging Java source code, you can only see the source code, but cannot see the immediate value of the variable in the source codeCause: In order to save space, the JRE removes debug information from the class file

ReentrantLock source code analysis for Java concurrent Series Before Java5.0, only synchronized and volatile can be used to coordinate access to shared objects. We know that the synchronized keyword implements the built-in lock, while the volatile keyword ensures the multi-thread memory visibility. In most cases, these mechanisms work well, but cannot implement s

上周末搬家后，家里的宽带一直没弄好，跟电信客服反映了N遍了终于约了个师傅明天早上来迁移宽带，可以结束一个多星期没网的痛苦日子了。这段时间也是各种忙，都一个星期没更新博客了，再不写之前那种状态和激情都要慢慢褪去了，总觉得心里慌的一逼，这怎么行呢？！趁明天周末，在公司电脑上记录下这周的一些学习内容。近期在看一本很经典的java书籍：《深入理解java虚拟机 第二版》，几年前也翻过，但那时候功力不够，不太能看懂就没看了。现在回过头来看，发现确实写的很好，很多知识点都能理解了，而且讲的也很有深度，收获颇多。后期计划按照这本书的内容写出一系列博客，来深入学习和复习下java虚拟机相关的知识。Fu Yun Source
