1. Experimental content
基于命令行和IDE（Intellj IDEA 简易教程](http://www.cnblogs.com/rocedu/p/4421202.html）进行简单的Java程序编辑、编译、运行和调试。（本次实验主要使用命令行的方式）
练习Linux基本命令；
学习Java程序的JDB调试技能：https://www.cnblogs.com/rocedu/p/6371262.html
编写简单的Java程序。2. Experimental procedure and results
在实验之前，我们需要在虚拟机上安装JDK程序才能进行编程，在结对同伴董其鹏同学的指导下，我完成了这一步。
实验第一步，我们打开终端并开三个窗口，然后用vim建立一个.java的文件，并输入实验代码。
然后把其他两个窗口其中一个用来编译并运行，一个用来单步调试。
关于单步调试：先在第三个窗口打下这样一段javac -g -d bin src/（你的文件名）.java ，然后用stop in/at +（你想要的断点位置）设置断点，之后可以用step或next进入下一步，用list或local查看，cont退出。
最后，完成这些步骤后把代码上交即可。3. Experimental problems encountered in the process and settlement process
- Question 1: javac compiler can not find the file
- Problem 1 Solution: When I create a vim xx instead of vim xx.java, re-edit.
- Question 2: Compile error.
- Problem 2 Solution: ";" not in English because I could not find the gap
- ...
Other (perception, thinking, etc.)
If only a simple Java program, I feel, and the term of C is not much difference, at best, the names of some of the same nature as the two other levels of different possible because I can not find the problem temporarily, but because there is no editor but operates directly under the linux system becomes the more difficult.
