1. 程序的组成 程序 (program):(1)由一系列定义计算机如何执行计算的指令组成.(本质) (2)程序(算法)由对象.表达式和语句组成.(元素) 1.1程序的指令类型 输入 (input): 从键盘.文件.网络或者其他设备获取数据. 输出 (output): 在屏幕上显示数据,将数据保存至文件,通过网络传送数据,等等. 数学 (math): 执行基本的数学运算,如加法和乘法. 有条件执行 (conditional execution): 检查符合某个条件后,执行相应的代码. 重复 (r

这个课程的参考视频和图片来自youtube. 主要学到的知识点有: 1. If-else statement if (x > 5) { System.out.println("Input x is bigger than 5. "); } else { System.out.println("Input x is not bigger than 5. "); } 2. Logical operators AND    && OR      ||

从7月29号到8月8号,断断续续地看完了这本书,做了部分实践联系.总体感觉本书真的只能算是个入门,学完之后看到库的那一章才感觉是个大坑,实践中大部分应该都是用的现成的库吧,所以还要重新学习一个库,但是这本书也算是给这门语言包括DOM的学习打下了个基础,明白了这些底层的东西,才能将库这些用的更好吧.总体来说,难度入门级,阅读体验良好.注:看完书一定要自己敲敲代码,会出现很多你意想不到的错误,自己学着调试找出错误并改正,这也是一项必备能力吧. 一.JavaScript简史 JavaScript语言使

In Java, the keywords include if-else,while,do-while,for,return,break, and a selection statement called switch. Java does not support the much-maligned goto. You can still do a goto-like jump, but it is much more constrained than a typical goto. true
