MultipleInheritance.java Lab #3 to be replaced with PetSpeak series

@sathyavathyvenugopal @rajasekaranap

As discussed, Please incorporate the PetSpeak series of CC problems in the lab manual.

http://j.mp/petSpeak1
http://j.mp/petSpeak2
http://j.mp/petSpeak3

Students must practice these in the lab, and once all the test cases pass, they can cut and paste into the NotePad and compile it locally as well and get the output to be verified by the lab in charge.

MultipleInheritance.java filename and class mismatch

@nandini-haricharan The classname does not match the filename. This is a basic error!

Create PetSpeak exercise series in Java

Rajasekaran (KITE) has been assigned this work.

Objectives of the Orientation

What are the objectives of the Orientation?

0. To get the students really interested in developing Java Programming Skills!
   http://www.fromdev.com/2015/02/programming-language-to-learn.html

"If someone wants to learn how to program, just sitting there pondering whether or not you should won't help. You need to just do it or you won't get far. Learning how to program requires determination and a playful attitude.
A thing that helped me learn how to program was enjoying the learning process. Instead of envisioning what it'll be like once you've learned how to program, try finding the joy in the learning process instead. Once you've created something new, even if it's just a small program, take a step back (not literally) and admire what you've created. Be proud of your creation, show it off to your friends and/or family."

1. "Lay of the Land", High Level review of the entire Subject Contents
2. Which is important for an immediate Java career @kgisl and the IT industry as a whole?

• https://www.quora.com/What-are-the-top-10-things-a-beginner-should-definitely-know-about-Java
• https://www.quora.com/What-are-the-concepts-every-Java-programmer-must-know

3. Where does Java fit in the overall technology stack that is used for developing an enterprise Application (like an Insurance solution)?
   • Write once, Run everywhere (including on a mobile phone running Android)
4. What is the REFCARDZ - how is it relevant?

Links to download, review, modify and distribute

@62ramya ?

Action items based on report

3. Send me the link.

Ideas for the Glossary

https://java.com/en/download/faq/helpful_concepts.xml

Definition of Java

Diving deep into Java

HashMap

http://j.mp/hashMapJava

Most of you will agree that HashMap is most favorite topic for discussion in interviews now-a-days. I have gone through several discussions with my colleagues time to time and it really helped. Now, I am continuing this discussion with you all.

I am assuming that if you are interested in internal working of HashMap, you already know basics of HashMap, so i am skipping that part. But if you are new to concept, follow official java docs.

Before moving forward, i will highly recommend reading my previous post : Working with hashCode and equals methods in java

ConcurrentHashMap

http://j.mp/concurrentHashmapJava

It allows concurrent access to the map. Part of the map called Segment (internal data structure) is only getting locked while adding or updating the map. So ConcurrentHashMap allows concurrent threads to read the value without locking at all. This data structure was introduced to improve performance.

Concurrency-Level: Defines the number which is an estimated number of concurrently updating threads. The implementation performs internal sizing to try to accommodate this many threads.

JVM presentation is key

@aBharathy I would imagine that this would be key. I've dumbed some screenshots from a video (http://j.mp/jvmVideo , ~3 minutes, from C to Java) which is the key to go from "Known to Unknown."

Handout Dockit During the Orientation

Handouts

0. Glossary of Important Terms and/or Concept Map
1. Learn Java in 21 minutes
2. REFCARDZ
3. Program output for PaintJava
4. Signup sheet for Mobile Hackshop and KGISL CCS Sessions
5. Sheet containing important links

Important Links

• The Mother of All Java Tutorials - @ the mother site - Oracle/SUN https://docs.oracle.com/javase/tutorial/
• What college students must know about Java -

WHO CAN Sponsor this?

Invite Sheeba and ? - the two trainers in Finishing School

Please get them github IDs and ask them to join the gitter room.

@62ramya @Dhivyakgisl - they can be asked to be programming mentors during the orientation.

Arrange for video recordings of the Orientation sessions

Compilation warning for ExceptionCheck

Needs to use the Scanner class instead of DataInputStream whose readLine function has been deprecated since JDK 1.1

200 Java problems in CC

Demonstrating Exception handling in Java

Divide by zero in C language

Divide by zero in Java

So, for Double zero, what will it be?

MCQ using a Survey tool

Please set this up.

We will use once PRIOR to start of the Orientation
And once AFTER the start of the Orientation

Use the questions to start with at https://github.com/kgashok/orientations/blob/master/mcqJava.md#mcq

Useful book to get to generate the MCQ?

Maybe there is a PDF somewhere?
Is this book available in the library?

Choosing an online IDE environment

The idea is to give them a sandbox for them to build and run Java programs on the cloud; including Applets

@Sudharsanrajendran Is Cloud9 the better alternative for Java IDE/development.
Research and provide some analysis.Or is it Heroku? Or should we provide multiple options?

or is it https://codenvy.com/

or https://cloud.oracle.com/application-development# (Oracle who owns Java)

The 4P - JCC Agenda

Why 4P?

• This is as much a Problem solving workshop as it is a Java workshop
  • CyberDojo/TDD (regardless of whether they will use it in their future workplace or not) will give them an teachable organized approach to problem solving
    • flowcharts, dry runs, pseudo code, etc. are the ways of the past (show me one programmer at KGISL who uses this?)
    • https://github.com/ryanmcdermott/clean-code-javascript#favor-functional-programming-over-imperative-programming - one more reason to learn Functions really well through TDD/CyberDojo
• This is about Perfect deliberate practice, thanks to doing in CloudCoder which should give accurate feedback
  - They will have "learned how to learn" a programming language.
• This is about being Paired on a 1:5 ratio with a real Java developer/trainer with at least 5+ years of experience in the technology
• This is about Persevering for two days at a stretch for at least 20+ hours until you really get the hang of it.

Follow-up Action Items

1. Invest in a laptop - provided you are willing to use it productively
2. Invest in improving keyboarding skills, especially through http://typing.io
3. Invest time in developing some projects (big or small, it doesn't matter). Come up with an idea and be ready to share it before the next workshop. Visit https://github.com/kgisl/project-ideas for inspiration.

Define collaborators and set deadlines

Paint in Java

Mentor Tools

• http://j.mp/hangTutor - Hangout + Tutor (visualizer) demo recorded on FizzBuzz. A combo tool which you can use to teach students remotely...(and be as good as next to them)

• http://www.javarepl.com - Java REPL

• http://j.mp/fizzBuzzV1 - visualize the Dynamic OOP version of FizzBuzz

Get Nandini H also into the Orientations

Does she have a github account?
Get her to join in the Gitter room as well

Reference books: Are they available in Moodle for this paper?

In KITE, they have scanned copies of the books. Is this done @KGCAS as well?
