In Java Fundamentals you will learn:Java Fundamentals is a comprehensive video course introducing the core elements of Java programming. In over 14 hours of professionally produced video, along with ample opportunities to try out what you’re learning, you’ll master the essentials in a friendly, easy-to-understand way. You’ll not only dig into the syntax and structure of the Java language, but also build up good habits and practices as you work with the many hands-on examples. As you progress from section to section, you’ll incrementally build a fully functioning application by adding and refining features.
With three decades of successful use in corporations large and small, Java is the dominant language for enterprise software. This 14-hour liveVideo course covers JavaSE versions 8, 11, and 17, and clearly explains the differences so that you can pick the version that works best for you. It’s the perfect entry point for any developer who wants to work with popular Java frameworks such as Spring, Apache Spark, Akka, or Android.
Java Fundamentals is your personal Java bootcamp. This liveVideo course is based on a well-established five-day live training program, updated and expanded by expert developer and trainer Matt Greencroft. This engaging course starts with the basics of Java programming and continues to build your skills to include advanced features like Lambda expressions, collections and streams, using databases, working with files, testing, and more. You’ll learn how to design programs from both the object-oriented and functional perspectives. As you go, Matt demonstrates his extensive Java knowledge, revealing interesting and unexpected details about the language that even experts might not have known! All the examples are practical and very relevant to your future career.
This course is suited for brand-new programmers who want a solid foundation in Java, and self-taught developers who want a more rounded education about the language. It’s also a good starting point for existing developers making the transition to Java programming. No previous programming experience is required.
Matt Greencroft has over 20 years of experience as a programmer, primarily working in the banking sector. Matt now teaches for Virtual Pair Programmers. His specialties are Microservices, Spring Boot, Apache Spark, and Kotlin.
