高级语言(high level language):类似Java这样的计算机语言,方便人们阅读,但在执行前需要翻译成机器语言。 HSB:一种颜色系统。其中颜色由3个数值表示(在Java中,实际的数值在0.0到1.0之间)。分别代表色调、饱和度和亮度。 IDE:集成开发环境。带图形用户界面的编程环境,集成了创建、编辑和执行程序的各种工具。
注解对于开发人员来讲既熟悉又陌生,熟悉是因为只要你是做开发,都会用到注解(常见的 @Override),陌生是因为即使不使用注解也照常能够进行开发,注解不是必须的,但了解注解有助于我们深入理解某些第三方框架(比如AndroidSupport Annotations、JUnit、xUtils、ActiveAndroid 等),提高工作效率。

Programming in machine code is an art of the past. The advantages of using a high-level language fairly compensate for the extra effort using the compiler chain. In technical documentation, the advantages, at least in the short run, are not so appealing. Creating a document using some ...
