ubuntu14.04安装MySQL5.6各种错，但是直接安装MySQL5.5就好了。

输入命令sudo apt-get install mysql-server-5.6 第一个问题的解决方式：https://help.aliyun.com/knowledge_detail/41124.html ``` 1.Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

2，数据库连接地址有误：url=jdbc:mysql://localhost:3306/test?3useUnicode=true&characterEncoding=utf8 3，密码或帐号有误：username=root password=root 4，数据库未启动或无权访问 5，项目未引入对应的驱动jar包mysql-connector-java-5.1.6-bin.jar 这五个错误我都看过，没毛病啊，半天光盯着这个错误了，求救！！！

volatile 与 synchronize 详解

Java支持多个线程同时访问一个对象或者对象的成员变量，由于每个线程可以拥有这个变量的拷贝（虽然对象以及成员变量分配的内存是在共享内存中的，但是每个执行的线程还是可以拥有一份拷贝，这样做的目的是加速程序的执行，这是现代多核处理器的一个显著特性），所以程序在执行过程中，一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段（成员变量），就是告知程序任何对该变量...

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它是一个过程，是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员必须掌握的核心算法有哪些？

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
