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?
