Course Recording Notes

Preview Video

Welcome to course on *** in ** simple steps.
I'm Ranga Karanam. I've so and so much experience with ... I've been using this framework for ...
At in28minutes, we ask one question everyday - How to create more effective courses? All our success - *** students on Udemy and *** subscribers on Youtube - is a result of this pursuit of excellence.
You will develop *** and *** using ***
You will learn the basics like *** and move on to the advanced concepts like ***.
You will use
- ... todo ...
- Maven for dependency management, building and running the application in tomcat.
- Eclipse IDE
All the code for this course and the step by step details are in our Github repository.
We have an awesome installation guide to help you install Maven and Eclipse. You are NOT expected to have any experience with Eclipse, Maven, or Tomcat.
What are we waiting for? Lets have some fun with *** in *** steps. We had a lot of fun creating this course for you and We are confident that you will have a lot of fun. I hope you are as excited as we are to learn more. Go ahead and enroll for the course. Or take a test drive with a free preview. See you in the course.

Course Intro Video

Welcome to this course on ***. We are excited to teach you how to build awesome ***.
In this video, we introduce you to the different sections of the course. By the end of the video you should have a clear idea of how to make the best use of the course.
We have organized this course into 6 different sections. We have designed each section to be independent of each other. That means, you have the flexibility of customizing the course based on your skills and your needs.
If you have experience with Spring and Spring Boot, you can skip these sections.
Lets get a quick overview of each of the sections now:
- Section I is an one hour introduction to Spring
- Section II is an one hour introduction to Spring Boot..
In summary this is your course. Feel free to create your own path and tailor it to your needs.
I will see you in the next video where we introduce you to our github repository

Overview of the Github Repository

Welcome Back. In this video, we give you an overview of how our github repository for this course is organized.
Github repository for this course is at ****.
Home page of the github repository has an overview of the course and installation guide
For each hands-on section of the course, we have a seperate folder in the repository. You can see these five folders for *** different sections
- Folder 1 contains ...
- Folder 2 contains ...
- Folder 3 contains ...
Each of these folders contain
- Step by Step details of the sections
- Complete code example at the end of the section
- Intermediate backups at different stages of the section
- Useful Links
For example, let's look at the folder for ***. Home page of the folder contains
- Step by step details : What are we going to do in each step
- Useful Links : Different links that would be useful during the course
- Complete Code, Snippets and Examples : Example code that your can use during the section. For example, If you are using a class and you do not know the package of the class, you can search here and quickly find what you would need.
- Intermediate Backups : You can download any of these zips and import them into Eclipse as maven projects. File > Import > Existing Maven Projects.
- Understanding our github repository is key part of making best use of this course. I recommend to spend some time with our github repository and I will see you in the next video.

Installation of Tools Video

In this video, we will help you install all the basic tools to get you started with the course
We use
- Maven for Dependency Management
- Eclipse as IDE
- ..
Step by step details to install Java, Eclipse and Maven are in the installation guide present here. Also included are links to 5 videos that will help you to install and trouble shoot installations.
If you have any problems during the course, we recommend you to look at the troubleshooting section of the installation playlist.
Get your tools ready and I will see you in the course

Each Section Introduction

Why is this section important to the course?
What is discussed in this section?
What is the github folder for this section?
Can a student skip this sections?
Is there a trouble shooting guide?
What are the backups available?
Are examples in this section dependent on any other section?

Conclusion Video

Congratulations! You have successfully completed the course on ... We covered a wide range of topics starting from Spring, Spring Boot to ..... I'm sure you had a lot of fun doing this course. If you loved this course, we would love to hear from you. Do not forget to leave us a review. Until we see you in another in28minutes course, here's bye from the team here at in28minutes.

About in28Minutes

At in28Minutes, we ask ourselves one question everyday. How do we help you learn effectively - that is more quickly and retain more of what you have learnt?
We use Problem-Solution based Step-By-Step Hands-on Approach With Practical, Real World Application Examples.
Our success on Udemy and Youtube (2 Million Views & 12K Subscribers) speaks volumes about the success of our approach.
While our primary expertise is on Development, Design & Architecture Java & Related Frameworks (Spring, Struts, Hibernate) we are expanding into the front-end world (Bootstrap, JQuery, Angular JS).

Our Beliefs

Best Courses are interactive and fun.
Foundations for building high quality applications are best laid down while learning.

Our Approach

Problem Solution based Step by Step Hands-on Learning
Practical, Real World Application Examples.
We use 80-20 Rule. We discuss 20% things used 80% of time in depth. We touch upon other things briefly equipping you with enough knowledge to find out more on your own.
We will be developing a demo application in the course, which could be reused in your projects, saving hours of your effort.
We love open source and therefore, All our code is open source too and available on Github.
