WORKSPACE-CS106

This is the Eclipse workspace that is to be used for CS106, CS165, and CS180. It includes:

• Eclipse preferences set to support easier coding in Java.
• The JavaCoreTemplate project: make a copy of this project when starting each assignment. The JavaCoreTemplate project supports the following goodies:

 

Main

Includes Main.java, with a main() function that is ready to go, and has useful classes statically imported.

println

Eliminate the EVIL System.out. and just use:

println("Hello");

readLine

Read a line of text from the console:

String s = readLine();

readFile

Read a whole file into a String with one line of code:

String quakeText = readFile("4.5_week.atom");

readFileAsLines

Read a file into a list of Strings:

List<String> words = readFileAsLines("dict.txt");

writeFile

Write a string to a file:

writeFile("file.txt", str);

writeFileAsLines

Write a list of strings to a file:

writeFileAsLines("lines.txt", list);

printf

printf w/o requiring System.out. in front:

printf("%d words in %s\n", words.size(), path);
print("Hello");

parseInt/Long/Float/Double/Boolean

Parse ints, floats, etc w/o having to put Integer. in front:

int age = parseInt(text);

asList

var list = asList("This", "That", "And the other");

range

Use range() to loop in a pythonic manner:

for (var x : range(10))
	println("Hello " + x);

join, substringsBetween, substringBefore, substringAfter, reverse, and more

JavaCoreTemplate includes the wonderful StringUtils, which has join, substringsBetween, reverse, etc. For example:

String[] titles = substringsBetween(quakesXml, "<title>", "</title>");

PMD

PMD support, including a tailored set of rules (cs106.ruleset).

 

STATIC IMPORT OF CORE FUNCTIONALITY

JavaCoreTemplate's Main class already has the Core functionality statically imported. To add Core functionality to other classes, add the following static import at the top of the .java file:

import static sbcc.Core.*;

 

TO USE

1. If you are using the SBCC Student Desktop VDI:

   1. Download workspace-cs106-v5.zip
   2. In Windows Explorer, copy the .zip file to the N:\ drive (CSnebula).
   3. Right-click the .zip file, select 7-zip | Extract Here. If asked about overwriting files, click Yes to All.
   4. Double-click the N:\CompSci\launchers\Eclipse CS106 shortcut. This will launch Eclipse and point it at N:\workspace-cs106_v5.
   5. If you get an "older version warning", check the "Do not warn again..." box and click Continue.

2. If you are on your own computer:

   1. Download workspace-cs106-v5.zip
   2. Unzip the workspace where you like.
   3. File | Switch Workspace | Other...
   4. Navigate to where you unzipped workspace-cs106-v5. ** NOTE: By default, Windows extracts and extra level of folder. I.e. your_folder/workspace-cs106-v5/workspace-cs106-v5. Double check this. If you have the "extra level", be sure to navigate to the inner level: your_folder/workspace-cs106-v5/workspace-cs106-v5.
   5. Click OK, then click OK again.
