From Zero To Hero: Learn Java Programming
- Taught by a Stanford-educated, ex-Googler, husband-wife team
- This course will use Java and an Integrated Development Environment (IDE). Never fear, we have a detailed video on how to get this downloaded and set up.
- Hundreds of lines of source code, and hundreds of lines of comments - just download and open in your IDE!
A Java course for everyone - accessible yet serious, to take you from absolute beginner to an early intermediate level
Let’s parse that.
- This is a Java course for everyone. Whether you are a complete beginner (a liberal arts major, an accountant, doctor, lawyer) or an engineer with some programming experience but looking to learn Java - this course is right for you.
- The course is accessible because it assumes absolutely no programming knowledge, and quickly builds up using first principles alone
- Even so, this is a serious Java programming class - the gradient is quite steep, and you will go from absolute beginner to an early intermediate level
- The course is also quirky. The examples are irreverent. Lots of little touches: repetition, zooming out so we remember the big picture, active learning with plenty of quizzes. There’s also a peppy soundtrack, and art - all shown by studies to improve cognition and recall.
- Programming Basics: What programming is, and a carefully thought-through tour of the basics of any programming. Installing and setting up an IDE and writing your first program
- The Object-Oriented Paradigm: Classes, Objects, Interfaces, Inheritance; how an OO mindset differs from a functional or imperative programming mindset; the mechanics of OO - access modifiers, dynamic dispatch, abstract base classes v interfaces. The underlying principles of OO: encapsulation, abstraction, polymorphism
- Threading and Concurrency: A deep and thorough study of both old and new ways of doing threading in Java: Runnables, Callables, Threads, processes, Futures, Executors.
- Reflection, Annotations: The how, what and why - also the good and bad
- Lambda Functions: Functional constructs that have made the crossover into the mainstream of Java - lambda functions, aggregate operators.
- Modern Java constructs: Interface default methods; properties and bindings too. Also detailed coverage of Futures and Callables, as well as of Lambda functions, aggregation operators. JavaFX as contrasted with Swing.
- Packages and Jars: The plumbing is important to understand too.
- Language Features: Serialisation; why the Cloneable interface sucks; exception handling; the immutability of Strings; the Object base class; primitive and object reference types; pass-by-value and pass-by-object-reference.
- Design: The MVC Paradigm, Observer and Command Design Patterns.
- Swing: Framework basics; JFrames, JPanels and JComponents; Menus and menu handling; Trees and their nuances; File choosers, buttons, browser controls. A very brief introduction to JavaFX.
Programming Drills (code-along, with source code included)
- A daily stock quote summarizer: scrapes the internet, does some calculations and outputs a nice, formatted Excel spreadsheet.
- A News Curation app to summarise newspaper articles into a concise email snippet using serious Swing programming
- Support with choosing a programming environment; downloading and setting up IntelliJ.
- Simple hello-world style programs in functional, imperative and object-oriented paradigms.
- Maps, lists, arrays. Creating, instantiating and using objects, interfaces
What are the requirements?
- No prior programming experience needed:)
- The class will make use of Java and an IDE - never fear, we have a detailed video to walk you through the process of setting this up
What am I going to get from this course?
- Write Java programs of moderate complexity and sophistication (at an early to middling intermediate level)
- Understand Object-Oriented programming concepts at the level where you can have intelligent design conversations with an experienced software engineer
- Manage concurrency and threading issues in a multi-threaded environment
- Create and modify files (including Excel spreadsheets) and download content from the internet using Java
- Use Reflection, Annotations, Lambda functions and other modern Java language features
- Build serious UI applications in Swing
- Understand the Model-View-Controller paradigm, the Observer and Command Design patterns that are at the heart of modern UI programming
- Gain a superficial understanding of JavaFX and Properties and Bindings
- Understand the nuances of Java-specific constructs in serialisation, exception-handling, cloning, the immutability of strings, primitive and object reference types
What is the target audience?
- Yep! Folks with zero programming experience - liberal arts majors, doctors, accountants, lawyers
- Yep! Engineering students from non-CS majors looking to learn fairly serious programming
- Nope! Experienced Java programmers - this class will be boring for you:)
- Yep! Computer Science students or software engineers with no experience in Java, but experience in Python, C++ or even C#. You might need to skip over some bits, but in general, the class will still have new learning to offer you :-)
