Course overview
Evolve your skills in Java programming with real-world applications
This five-day course deepens your understanding of Java through practical examples and exercises. You’ll leave equipped to write functional Java applications and pursue professional Java certification.
Learning objectives
- Write and execute Java programs
- Design and use objects and classes
- Control program flow with loops
- Utilise Java collections
- Implement exception handling
- Manipulate and format strings
- Apply inheritance and polymorphism
- Perform file I/O in Java
- Interact with databases using JDBC
- Develop modular applications using Java
What you’ll learn
Discover how Java supports object-oriented development by learning its key features and syntax. You'll develop practical experience writing and refining real Java code for your current or next role.
Managing exceptions effectively
Learn to build more resilient applications by handling errors in a structured and reliable way. You’ll use try-catch blocks to manage exceptions, apply finally statements for resource management, and write your own custom exceptions. These techniques will help you anticipate common runtime issues, recover gracefully from faults, and produce Java code that’s robust, secure, and maintainable.
Inheritance, interfaces, and abstraction
Explore the key object-oriented principles that make Java code flexible and extensible. You’ll use inheritance to share behaviour between classes, override methods to customise functionality, and implement interfaces to design modular, reusable components. This section deepens your understanding of abstraction and polymorphism, equipping you to build applications that are easier to scale, maintain and adapt as requirements evolve.
Building modular applications and file handling
Structure your Java applications using the module system and handle file input and output with modern APIs. You’ll work with buffered streams and the Path class to read and write data, then use tools like jdeps and jlink to analyse dependencies and package standalone apps. These are essential skills for building clean, deployable applications in real-life environments.
Database connectivity with JDBC
Integrate your Java applications with relational databases using JDBC, the standard API for database access. You’ll learn how to load drivers, connect to databases, and execute queries. Beyond the basics, you’ll manage transactions, handle result sets, and use prepared and callable statements — building the confidence to work with live data in professional-grade software projects.

FAQs
This immersive Java Programming course builds your core Java skills, helping you build applications from scratch and preparing you to move forward with advanced training and exams.
What if I’m new to Java but have experience with another language?
That’s fine. If you’re already comfortable with general programming concepts (like variables, loops, and control structures) you’ll be well placed to start learning Java with this course.
Does the course use the latest version of Java?
Yes. This course is delivered using Java 17, giving you exposure to modern features and practices that are relevant in today’s job market.
How interactive is the virtual training?
Very. ILX courses are instructor-led and include live coding demonstrations, real-time lab activities, and the opportunity to ask questions and get feedback during the session. This helps reinforce your understanding, builds confidence with each concept, and ensures you can apply your new skills effectively.
Can I review the materials after the course ends?
Yes. You’ll have access to digital courseware and reference materials after the course so you can continue practising and revisit key concepts.
Will this course support me to gain the skills for developer jobs?
While no course guarantees employment, this course provides a strong technical foundation in Java and is a recognised first step towards certification and junior developer roles.
