Berkeley CS 61B Data Structures(in Java) Lab1 讨论帖

作业入口：http://www.cs.berkeley.edu/~jrs/61b/lab/lab1/

看完第二课视频Using objects就可以做这次的作业。
   第一次作业实在是没什么好说的，咱们没有TA给我们Check off,也没有Emacs可以用。我看了一下，咱们能做的只有把那个有错误的names.java改对。


  作业要求：
       1.load the program file Names.java
       2. build a command line to run the Java compiler:        javac -g  Names.java
       3. You will find that javac cannot compile the program.  The code contains two syntax errors which you are quite likely to make when you will write programs.
      (The second error won't rear its head until you fix the first one.)       
       4.Figure out what's wrong, correct the errors, save the file, and compile the code.      
       5. 可以编绎了以后，还有些Run-time Error, 把那些改对，运行成功了，就可以交差了。  

This homework assignment is meant to make sure you can write, compile, and runsimple Java programs.  This is an individual assignment; you may not sharecode with other students. You will need to know how to compile and run Javaprograms, as described in Lab 1.

Lab贴不加分~~~只讨论！！！

done by eclipse

该lab1用于熟悉运行java程序的流程；
借鉴回复用了eclipse作为ide；
其中涉及在eclipse中的文件操作，如：
create new java project; put java program in workspace; ...
之后能够对程序进行edit, compile, run操作；
代码本身：
主要涉及string methods;
compile error; run-time error的修改；
结果如下：

1. Environment: Emacs & shell with Emacs


2. Sort the file roster.txt with sort-lines function within Emacs

**最后还是借助了IDE，Emacs实在玩不转╮(╯▽╰)╭

这样附截图不知道可以不~

不知道发上了没有~这是自己用mac 的terminal compile的~不知道可行吗？

哪里有Emacs玩呀？

就是在Lab1里面的，readme里面

4. Load the program file Names.java into Emacs using C-x C-f.  "C-x" is read
"control x," and is typed by holding down the control (Ctrl) key while typing
"x".  You may need to type the full pathname lab1/Names.java, then hit Enter.

Names.java is a simple program for performing various string operations on a
name.  It almost works, but you need to make some changes so that it compiles
and runs correctly.

5. Compile the program within Emacs using:
        C-x C-e

他们是用Emac编译的

版主辛苦啦

“eMac是早期苹果出品的面向学生的一体机,当初定位就很低端,而且早就停产了,配置方面在当时就不高,更不用说现在了。”

  所以这是个苹果产品。。或者苹果机里的一个软件么？

在ubuntu下装了个emacs，但是还是搞不定，最后还是用terminal run的

没有，emacs是个功能强大的文本编辑器，以下摘自wikipedia的介绍
Emacs /ˈiːmæks/ and its derivatives are a family of text editors that are characterized by their extensibility. The manual for the most widely-used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor".[1] Development of the first Emacs began in the mid-1970s and continues actively as of 2014. Emacs has over 2,000 built-in commands and allows the user to combine these commands into macros to automate work. The use of Emacs Lisp, a variant of the Lisp programming language, provides a deep extension capability.
