Spring Boot Microservices with JPA

Spring Boot Microservices with JPAa.jpg

This course is a practical course which explains how to realise a microservice infrastructure in order to realise a full-stack web application composed by a “framework-less” Single Page Application and two restful Spring Boot microservices interacting with each other and with two different databases thanks to the implementation of the JPA (Java Persistence Api).

You’ll have the basis to generate fastly a microservice infrastructure, to organise your application using different layers according to the “SOLID” principle and following the MVC pattern.

You will have the instrument to organise your communication protocols using simple and effective rules, to implement restful web services which communicate with Json Messages.

This is course has the same topic of the Italian course Sviluppo Web a Microservizi con Java Spring Boot e Ajax” so it can easily considered as its English version. The example developed is different but with the same topics: microservices, Spring Boot, JPA and Rest calls.

Who is the target audience?

  • Anybody who wants to understand microservice infrastructure and the difference existing between monolithic application and microservices
  • Anybody who wants to learn Spring Boot and how to realize fastly a microservice infrastructure using this precious instrument
  • Anybody who wants to understand the difference between the classical use of Spring MVC and its implementation through Spring Boot
  • Anyone who wants to learn the basis of JPA (Java Persistence Api) in order to interact with Databases
  • Anyone who wants to learn how to implement Restful Web services using a microservice infrastructure
  • Anyone who wants to learn how to consume Restful web service either from the user interface than from server-side code
  • Anyone who want to have a basic idea on Single Page Applications and how they works
  • Anyone who wants to realise a full stack web application using the most modern technologies and approaches
  • Anyone who wants to learn how Ajax calls and javascript can be used to let our web pages become dynamics
  • Anybody who wants to understand how to generate a dynamic web page using multiple resources con temporarily

Data Structures & Algorithms in Java

Data Structures & Algorithms in Java.png

This is an animated, visual and spatial way to learn data structures and algorithms

  • Our brains process different types of information differently – evolutionarily we are wired to absorb information best when it is visual and spatial i.e. when we can close our eyes and see it
  • More than most other concepts, Data Structures and Algorithms are best learnt visually. These are incredibly easy to learn visually, very hard to understand most other ways
  • This course has been put together by a team with tons of everyday experience in thinking about these concepts and using them at work at Google, Microsoft and Flipkart

What’s Covered:

  • Big-O notation and complexity
  • Stacks
  • Queues
  • Trees
  • Heaps
  • Graphs and Graph Algorithms
  • Linked lists
  • Sorting
  • Searching

Programming And Coding Interviews

Programming And Coding Interviewsf.jpg

Programming interviews are like standard plays in professional sport – prepare accordingly. Don’t let Programming Interview gotchas get you down!

  • Programming interviews differ from real programming jobs in several important aspects, so they merit being treated differently, just like set pieces in sport.
  • Just like teams prepare for their opponent’s playbooks in professional sport, it makes sense for you to approach programming interviews anticipating the interviewer’s playbook
  • This course has been drawn by a team that has conducted hundreds of technical interviews at Google and Flipkart

What’s Covered:

  • Pointers: Memory layout of pointers and variables, pointer arithmetic, arrays, pointers to pointers, pointers to structures, argument passing to functions, pointer reassignment and modification – complete with visuals to help you conceptualize how things work
  • Strings: Strings, Character pointers, character arrays, null termination of strings, string.h function implementations with detailed explanations
  • Linked lists: Visualization, traversal, creating or deleting nodes, sorted merge, reversing a linked list and many many problems and solutions, doubly linked lists
  • Bit Manipulation: Work with bits and bit operations
  • Sorting and searching algorithms: Visualize how common sorting and searching algorithms work and the speed and efficiency of those algorithms
  • Recursion: Master recursion with lots of practice! 8 common and uncommon recursive problems explained. Binary search, finding all subsets of a subset, finding all anagrams of a word, the infamous 8 Queens problem, executing dependent tasks, finding a path through a maze, implementing PaintFill, comparing two binary trees
  • Data Structures: Understand queues, stacks, heaps, binary trees and graphs in detail along with common operations and their complexity. Includes code for every data structure along with solved interview problems based on these data structures
  • Step-by-step solutions to dozens of common programming problems: Palindromes, Game of Life, Sudoku Validator, Breaking a Document into Chunks, Run Length Encoding, Points within a distance are some of the problems solved and explained

Design Patterns – 24 That Matter – In Java

Design Patterns - 24 That Matter - In Java.jpg

  • Prerequisites: Basic understanding of Java
  • Taught by a Stanford-educated, ex-Googler, husband-wife team
  • More than 50 real-world examples

This is an intensely practical, deeply thoughtful, and quirky take on 24 Design Patterns that matter.

Let’s parse that.

  • The course is intensely practical, bursting with examples – the more important patterns have 3-6 examples each. More than 50 real-world Java examples in total
  • The course is deeply thoughtful, and it will coax and cajole you into thinking about the irreducible core of an idea – in the context of other patterns, overall programming idioms and evolution in usage
  • 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
  • Lastly, the patterns matter because each of these 24 is a canonical solution to recurring problems

What’s Covered:

  • Decorator, Factory, Abstract Factory, Strategy, Singleton, Adapter, Facade, Template, Iterator, MVC, Observer, Command, Composite, Builder, Chain of Responsibility, Memento, Visitor, State, Flyweight, Bridge, Mediator, Prototype, Proxy, Double-Checked Locking and Dependency Injection
  • The only GoF pattern not covered is the Interpreter pattern, which we felt was too specialized and too far from today’s programming idiom; instead we include an increasingly important non-GoF pattern, Dependency Injection
  • Examples: Java Filestreams, Reflection, XML specification of UIs, Database handlers, Comparators, Document Auto-summarization, Python Iterator classes, Tables and Charts, Threading, Media players, Lambda functions, Menus, Undo/Redo functionality, Animations, SQL Query Builders, Exception handling, Activity Logging, Immutability of Strings, Remote Method Invocation, Serializable and Cloneable, networking
  • Dependency Inversion, Demeter’s Law, the Open-Closed Principle, loose and tight coupling, the differences between frameworks, libraries and design patterns

  • 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.
