Java for Beginners

Java is one of the most used and appreciated programming languages of the moment. Large, multinational companies develop applications for other multinational companies using Java. In the last decade Java began to spread in various fields of activity: from banking and health care to online shopping and entertainment. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Get started with the basic and discover the beautiful world of OOP programming with this accessible and easy to understand Java course.

    Getting Started with Java
    About: Getting started with Java. Learn how to write your first Java program, compile it and run it. We start with the basic elements of the Java language: semantics, syntax, key word, data types and operation. Learn to control the flow of execution by using control structures: if/else, for, while and case.
    Requirements: Eclipse, NetBeans or IntelliJ, JDK, Java Home correctly set

    Object Oriented Programming
    About: One of the most important principles of Java is Object oriented Programming or OOP. Learn how to use Interfaces and Abstract Classes to extend the behaviour of existing classes or for hierarchy of classes with a common shared functionality.
    Requirements: JDK, IDE
  • 3
    Inheritance and Interfaces
    About: Interfaces play a great role in the overall design of Java. Most of the things that are implemented in the latest versions of Java utilize Interfaces or Design by contract to ensure that multiple classes have the same functionality, but with classes specific particularities.
    Requirements: JDK, IDE, OOP Concepts

    Data Flows and Exception Management
    About: Learn the concepts of data flows and exception management. Read and write files on the file system, navigate through directories and learn the proper way of dealing with exception in Java. Learn how Exception Management is more of a language constraint rather than a feature and understand why this mechanism allows for a logical, easily understandable way of dealing with errors and exceptions.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces

    About: Learn the concepts of generics, the mechanism that ensures and enforces compile-time type safety in Java. This mechanism uses parameters when defining classes, interfaces and methods. Much like formal parameters used in method declarations, type parameters provide a way for you to re-use the same code with different inputs. The difference is that the inputs to formal parameters are values, while the inputs to type parameters are types.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces

    About: All application are used to manipulate data in a way or another. Regardless of the nature of the application, most of the time data is organized in lists of elements that have the same type. It is only natural to have multiple ways to data in forms of lists, maps or trees. In this course we will learn how all collection types in Java work and understand their strengths and weaknesses and when they should be used.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces, Generics

    Swing - UI
    About: Learn to create and interact with the graphical user interfaces(GUI) in Java. Learn about frames, menus, trees and most importantly the way Java handles events. While this may be considered by some to be an outdated technology, it serves as a good starting point for learning how other Java based frameworks work. While the implementation has changed the principles remain the same.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces, Generics

    About: Learn how to execute parallel tasks in Java, making your application faster and smarter. Learn the way that Java handles parallel and asynchronous operations. The need for optimization has always been a mandatory feature of any application; while there are other ways to handle multi-threads operations, threads remain the most used approach for this.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces, Generics
  • 9
    Network Programming
    About: Learn how to create network applications. Understand the communication protocols and practices and how to identify resources located in the network. if you ever played multi-player games and you hoped that one day you will build one this is a very good place to start. Understand how Java application communicate over various network protocols and how some features are mandatory for web application development in Java.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces, Generics, Threads
  • 10
    Databases and JDBC
    About: Learn how connect and communicate with a database server. Understand the ways Java can connect to various databases and how we can perform CRUD(create, read, update, delete) operations on a database table. Understand the JDBC driver approach and how to use drivers to create database connection. See the ways Java offers to communicate with database server for executing queries, updates and even stored procedures and functions.
    Requirements: JDK, IDE, OOP, Inheritance, Interfaces, Generics, Threads, Network Programming
