Course description

Java is everywhere and is as popular as ever. This hands-on course, delivered using Java 11, endeavours to provide the fundamental skills you need to become a Java Developer. We'll have you build a series of realistic apps focusing on object-oriented principles from the start.

Note that this is not a beginners course. You are expected to be familiar with programming concepts and have a little coding experience. If not you should consider our Learn to Code with Java course instead.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Skills Gained

The delegate will learn and acquire skills as follows:

  • Construct a Java app; perform basic IO
  • Declare classes; instantiate and use objects
  • Differentiate between primitives and references; exploit the standard data types
  • Code decisions and loops
  • Group data using ArrayList and HashMap
  • Make the case for and code static fields and methods
  • Manage numbers and perform computations using the Math and BigDecimal classes
  • Process Strings and perform pattern matching
  • Manage exceptions
  • Hide an object's data and its internal workings
  • Build objects that are composed of others
  • Build objects that inherit state/behaviour from others
  • Build flexible and scalable apps by exploiting abstraction and polymorphism
  • Read from and write to files and databases
  • Build a standalone executable from one or more modules
Who will the Course Benefit?

The Java Developer course is aimed at anyone with a little coding experience seeking to become a Java Developer, and existing developers seeking to migrate to Java.

Course Objectives

This course aims to provide the delegate with the skills needed to build object-oriented apps using Java that exploit all of the fundamental elements of the language.

Examinations

Whilst not strictly aligned to it, this course is a good choice for anyone intending to take Oracle's Java SE 11 Programmer I exam. All of the headline exam topics are covered though additional preparation is likely to be required.

Requirements

Delegates attending this course should be able to define general programming concepts including compilation and execution, variables, arrays, sequence, selection and iteration, navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.

Pre-Requisite Courses

I have a few disabilities - particularly with my vision - which did make it a bit slower for myself on the course. Alan appreciated this, and adapted his teaching style to compensate for my slowness, so that i would get as much benefit & confidence from the course as given to the other delegates; Which I did. Thank you very much, Alan. Ala...
