This fast-paced instructor-led online course covers Java application development.

During the course, we assemble an ecommerce type Web Application, using Dependency Injection to connect application layers. A Repository Layer maps entity classes to a MySQL database using Spring Data Persistence. A Service Layer contains business logic and a Web Service is implemented as a REST Controller Layer with Spring. HTML User Interfaces to the web service are built with Bootstrap and jQuery AJAX.

• Java Programming Introduction
• The Java collections framework and building a domain model
• Lambda expressions and the Stream API
• Asynchronous and concurrent programming and interacting with a database using JDBC
• Using Spring Boot to build a REST service that connects to a database
• Building a Spring ecommerce type application, using jQuery Ajax to call Spring controller methods

Java Programming

• JDK 14 tools including javac, java, jar and javap
• Setting up the IntelliJ Development Environment
• Keywords; primitive types; conversion and casting; operators

Java Collections Framework

• Generic classes and interfaces; the collections hierarchy
• Using implementations of the List, Set and Deque interfaces
• Overriding the equals and hashCode methods
• Using Big O notation and relative speeds of collection methods
• Wrapper classes; dates and times; enums; domain classes

Lambda expressions and the Stream API

• Functional interfaces, anonymous inner classes and lambda expressions
• Filtering and projecting data with the Stream interface and collecting results
• Primitive streams and the Optional class

Spring Data and REST

• Building and running a simple Spring Boot application with IntelliJ and Maven
• Describing application layers with UML class and sequence diagrams
• Building a Service layer and injecting dependencies
• Building Repository classes with CrudRepository; associations between entities; using the query builder mechanism
• Configuring the application to connect to the MySQL database
• Mapping HTTP requests to Controller methods; responding to HTTP GET, POST, PUT and DELETE
• Handling exceptions and returning appropriate HTTP responses; testing the Web Service with Postman

Spring Application with UI

• jQuery syntax, selectors and events
• Calling the web service with jQuery ajax
