More about this course

Our Java training course introduces you to OO Programming with Java language.  We show you that while it is reletively easy to learn the basic syntax, effective use of Java requires understanding of the many features of the language. The new features introduced into Java 8 and beyond expand the opportunities offered by Java. The introduction of lambda functions and streams support a functional programming style, as well as the traditional object oriented style and related concepts of Inheritance and the role of interfaces. The mixture of these allows faster, easier  programming, resulting in you being able to develop software that is more flexible and easier to maintain..

Java is a general-purpose, object-oriented programming language first released by Sun Microsystems in 1995 and now maintained by Oracle. It compiles source code into bytecode that runs on the Java Virtual Machine (JVM), making Java applications platform-independent — able to run on any device with a JVM installed, regardless of operating system. Java is widely used in enterprise application development, financial services systems, Android mobile development, large-scale backend services, and distributed systems. Its longevity, stability, extensive ecosystem of libraries and frameworks, and strong enterprise adoption mean that Java remains one of the most in-demand programming languages globally, used by banks, retailers, insurers, telecoms, and public sector organisations worldwide.
The Java Introduction course is a five-day programme for developers who are new to Java or coming from another programming language. It covers the Java environment, core object-oriented programming concepts, basic and advanced syntax, generics, lambda expressions, streams, Swing UI, JDBC for database connectivity, threading, and networking. The Advanced Java course is a four-day programme for experienced Java developers who want to go deeper into the language. It covers subjects that receive cursory treatment in introductory courses — including advanced generics, multithreading and synchronisation, socket programming, annotation development, and applying Java 8 and beyond platform features in complex application scenarios. Delegates should have solid working Java experience before attending the Advanced course.
Spring Boot is a framework built on the Spring ecosystem that simplifies the configuration and deployment of Java applications — particularly microservices. It eliminates much of the boilerplate configuration required by traditional Spring applications and provides production-ready features such as embedded servers, health monitoring, and metrics out of the box. JBI's four-day Spring Boot Microservices course covers the fundamentals of microservices architecture, building RESTful microservices with Spring Boot, service discovery and communication between services, securing microservices, containerising Spring Boot applications with Docker, and deploying to cloud environments. It is one of JBI's most popular courses and is highly relevant for Java developers working in modern cloud-native application environments.
Kotlin is a modern, statically typed programming language developed by JetBrains that runs on the JVM and is fully interoperable with Java. It was designed to be more concise, expressive, and safer than Java — reducing boilerplate code, eliminating common sources of null pointer exceptions, and supporting both object-oriented and functional programming styles. Kotlin is now Google's preferred language for Android development and is widely used for server-side JVM development as well. Existing Java codebases can call Kotlin code and vice versa, making Kotlin a natural evolution path for Java development teams. JBI offers one of the UK's most comprehensive Kotlin training curricula, covering introductory through to expert level.
JBI offers a structured progression of Kotlin courses. Kotlin (three days) is the introductory course for developers new to the language. Kotlin Beyond the Basics (three days) extends core knowledge into more advanced language features. Kotlin Best Practices (three days) focuses on idiomatic Kotlin, code quality, and professional development patterns. Kotlin Mastery (three days) covers advanced functional programming, DSL construction, and sophisticated language features. Kotlin Expert (two days) is for senior Kotlin developers targeting expert-level command of the language. Kotlin Coroutines (three days) covers Kotlin's approach to asynchronous and concurrent programming. Kotlin for Testers (three days) focuses on using Kotlin in test automation. Android Development with Kotlin (three days) covers building Android applications. Compose Essentials (two days) covers Jetpack Compose, Google's modern UI toolkit for Android. JBI can advise on which course best matches your current level and role.
Go (commonly known as Golang) is an open-source programming language developed by Google, designed for simplicity, performance, and efficient concurrent programming. It is widely used for building cloud services, APIs, command-line tools, and distributed systems — and is the language underlying major infrastructure projects including Docker, Kubernetes, and Terraform. JBI's three-day Go course covers the Go language fundamentals, types and control flow, functions and methods, interfaces, concurrency with goroutines and channels, error handling, testing, and building practical applications in Go. It is suited to experienced developers from other languages — particularly Java, Python, or C++ — who are adopting Go for systems or cloud-native development.
RxJava is a Java implementation of ReactiveX — a library for composing asynchronous and event-based programs using observable sequences. It allows developers to build applications that react to streams of data or events in a declarative, composable way — making it particularly useful for building responsive, scalable applications that handle concurrent operations, user interactions, or data streams without blocking threads. RxJava is widely used in Android development and in backend Java applications that need to handle high concurrency or event-driven workflows. JBI's three-day RxJava course covers the core reactive programming concepts, observable and observer patterns, operators, threading and schedulers, and practical application in Android and server-side Java contexts.
The AI-Assisted Java Development course is a three-day programme that teaches Java developers how to work professionally and effectively with AI coding assistants in a Java development context. It covers how to write clear specifications and prompts for AI coding agents, how to critically evaluate AI-generated Java code for correctness, design quality, and security, how to apply test-driven development as a verification discipline when working with AI-generated code, and how to integrate AI coding tools — such as GitHub Copilot and Claude Code — into a professional Java development workflow without compromising code quality or architectural standards. It is designed for practising Java developers who want to use AI coding tools more effectively and responsibly.
Yes. All Java, Kotlin, Spring, and JVM-related courses at JBI can be delivered as customised onsite or online programmes for corporate development teams. Content and exercises can be tailored to the team's existing codebase, frameworks in use, Java version, application domain, and specific learning objectives. For example, a team migrating from Java to Kotlin can receive a tailored programme covering interoperability, idiomatic Kotlin patterns, and migration strategies. A team adopting Spring Boot for microservices can receive training focused on their cloud environment and deployment toolchain. JBI has delivered Java and Kotlin training for development teams at organisations including the BBC, NHS, RBS, Sky, EDF, and Cisco.
Yes. Java follows a six-monthly release cycle and Kotlin is updated regularly by JetBrains. JBI's training content is continuously reviewed to reflect the latest stable versions of both languages, including new Java language features introduced in recent LTS releases, updates to the Spring and Spring Boot ecosystem, new Kotlin language features and coroutines improvements, developments in Jetpack Compose for Android, and the evolving role of AI coding assistants in JVM-platform development workflows. Delegates learn skills that are current and applicable to the versions and tools used in professional Java and Kotlin development today.
