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?

坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...
