This is a quick and handy course with exactly what you need to know (nothing more, nothing less!) about the MVC paradigm in Java.
Let’s parse that.
Using discussion forums
Please use the discussion forums on this course to engage with other students and to help each other out. Unfortunately, much as we would like to, it is not possible for us at Loonycorn to respond to individual questions from students:-(
We're super small and self-funded with only 2-3 people developing technical video content. Our mission is to make high-quality courses available at super low prices.
The only way to keep our prices this low is to *NOT offer additional technical support over email or in-person*. The truth is, direct support is hugely expensive and just does not scale.
We understand that this is not ideal and that a lot of students might benefit from this additional support. Hiring resources for additional support would make our offering much more expensive, thus defeating our original purpose.
It is a hard trade-off.
Thank you for your patience and understanding!
he Model-View-Controller (MVC) paradigm is ubiquitous in UI programming; along with the Observer and Command patterns, MVC has practically defined modern User-Interface programming.
Models contain data, views define the UI, and controllers respond to user input and update the model and the view. We see how this plays out in a Charting application.
The Observer Pattern, along with the MVC and Command Patterns, has practically defined modern UI programming. Publishers publish updates when their state changes, and Subscribers can listen in on these updates. An event is fired when the state changes, and the listener responds via a Command object called the event listener code.
Java has recently added substantial language support for the Observer Pattern via two new types of objects - Properties and Bindings. Let's understand when these types of variables can save us a bunch of work.
More on the newly added language constructs for the Observer Pattern, Properties and Bindings. We dig deep into the mechanics and underlying interfaces.
We dig deep into the interplay between the Model-View-Controller and the Observer Pattern, tied together via the Command Pattern. These three patterns have, together, defined modern User-Interface programming
Models contain data, views define the UI, and controllers respond to user input and update the model and the view. We see how the Observer Pattern plays a crucial role in seting up this MVC example for success - for instance, a slider that wires up the volume of the media is just about 1 line to set up correctly.
The Command Design Pattern is used to separate an action from its execution. A seemingly abstract idea, and an incredibly powerful one. The Command Pattern, along with the Observer and MVC Patterns, has practically defined modern User Interface Programming.
We continue with functional-programming support in Java. In addition to lambda functions, there are also powerful aggregate operators - map, foreach and filter - that we can use to chain lambda functions together
The Command Design Pattern is used to separate an action from its execution. We see how this idea is used as the starting point of most modern Threading libraries. Java has old-school and new ways of getting Multi-threading done, and both of these start with the Command Pattern
The Command Design Pattern is used to separate an action from its execution. This idea serves as the basis of two really neat applications: implementing Undo, and logging activity. Let's see how.
Loonycorn is us, Janani Ravi, Vitthal Srinivasan, Swetha Kolalapudi and Navdeep Singh. Between the four of us, we have studied at Stanford, IIM Ahmedabad, the IITs and have spent years (decades, actually) working in tech, in the Bay Area, New York, Singapore and Bangalore.
Janani: 7 years at Google (New York, Singapore); Studied at Stanford; also worked at Flipkart and Microsoft
Vitthal: Also Google (Singapore) and studied at Stanford; Flipkart, Credit Suisse and INSEAD too
Swetha: Early Flipkart employee, IIM Ahmedabad and IIT Madras alum
Navdeep: longtime Flipkart employee too, and IIT Guwahati alum
We think we might have hit upon a neat way of teaching complicated tech courses in a funny, practical, engaging way, which is why we are so excited to be here on Udemy!
We hope you will try our offerings, and think you'll like them :-)
