Course Overview

Fast Track to Java 17 Programming for OO Developers is a four-day, engaging hands-on course that helps experienced object oriented developers (coming from C++, C#, etc.) quickly get up and running with programming in Java, using the latest coding skills. You’ll exit the course well-prepared to tackle real-world programming tasks, equipped with an in-depth knowledge of Java and a practical skill set to create robust, efficient, and secure Java applications.

Working in a skills-immersive, hands-on learning environment led by our expert instructor, you’ll explore the intricacies of the Java platform and the Java Standard Edition, working seamlessly with the Java Development Kit (JDK), and using the development environment (IDE) proficiently. The course emphasizes best practices in OO development, reinforcing core object-oriented principles such as inheritance, polymorphism, interfaces, and abstract classes, allowing you to design software applications, develop back-end systems, or contribute to enterprise-level projects.

The course centers around applying these skills to real-world challenges, ensuring you can leverage them in your role or project right after class. Throughout the course you'll build applications, create subclasses, and develop custom exception handling. You'll also gain proficiency in using Java's arrays, records, packages, and utility classes. The course also delves into the advanced features of Java programming, including working with generics, understanding functional programming with lambda expressions, and using the Collection API. You'll be proficient in the JDK, be able to navigate your course IDE, and will be able to develop complex Java programs.

You’ll exit this course equipped with the skills required to tackle a variety of programming challenges and create efficient, robust Java applications with ease.

Course Objectives

This course combines engaging instructor-led presentations and useful demonstrations with valuable hands-on labs and engaging group activities. Throughout the course you’ll:

Master the fundamentals of the Java platform and the Java Standard Edition. This foundation will empower you to make the most of these tools, and confidently navigate the Java ecosystem.
Get hands-on with the Java Development Kit (JDK) and become comfortable with the IDE / development environment. These are key tools that will become part of your everyday programming toolbox.

Engage in practical, real-world programming challenges through hands-on lab sessions. You'll become skilled in using arrays, records, packages, and utility classes, enhancing your ability to build robust and efficient Java applications.
Dive into advanced Java programming concepts, exploring the use of generics, lambda expressions, functional interfaces, and the Collection API. This will equip you to tackle complex programming tasks and take your coding skills to the next level.
Develop a deep understanding of exception handling in Java. Learn how to define your own exceptions, handle multiple exceptions, and use try/catch blocks. This will help you to create more reliable and fault-tolerant code.
Explore and understand the Java Modular System and its impacts on accessibility and visibility. You'll become adept at executing Java applications, defining modules, and dealing with dependencies.
Gain proficiency in working with collections in Java, which includes learning about the different collection implementations (Set, List, and Queue), using iterators, and sorting collections. This will enable you to manage data effectively in your Java programs.
Explore specific Java 17 features that are covered in the course including: Switch Expressions, Text blocks, Pattern matching for instanceof, Introduce records as carrier of immutable data

If your team requires different topics, additional skills or a custom approach, our team will collaborate with you to adjust the course to focus on your specific learning objectives and goals.

Course Prerequisites

This introductory-level course is an excellent fit for developers, software engineers, and IT professionals who have hands-on prior object-oriented programming experience (as in C++, C#, etc.) and are seeking to broaden their skills into Java programming.

To ensure a smooth learning experience and maximize the benefits of attending this course, you should have prior hands-on programming experience in another OO programming language such as C# or C++. This course is not for non-OO developers, or non-developers.

The voices of our customers speak volumes

A very good balance of teaching time to lab time. I've done other courses that I found to be much lighter on content and heavy on labs to waste time. This was a refreshing change of pace.

Adam G

Excellent training. Even though it was online, I did not have any issues understanding or getting the answers for the questions I had. The lab exercises are interesting to apply what was learnt. Overall very good training. Thank you!

Anitha

Both the instructor and the course material were very thorough - the course material has many helpful references - the labs were well laid out, making it easy to learn from and get done on time

Steve C.

Best programming class I've ever been in, head and shoulders above any thing I took in college as part of a computer science degree. The instructor was thorough and very detailed, he was very good abut explaining all possible scenarios a situation would apply to. The way the albs were structured and the class was conducted was very good for interaction and hand on learning.

Danish J

First time in my life I have attended remote class and I find it great. Personally I don't feel there is any area which require improvement!

Rishi M

Great job overall. Great communicator and explained complex concepts in a simple, easier to understand format.

Jeremy G

The instructor was clearly knowledgeable about Java and programming in general. He was very attentive to every student's individual needs and constantly encouraged questions, concerns, student issues to be raised and addressed each one thoroughly.

Mark M

Excellent detail about the Spring framework which directly relates to my role as a senior engineer. I found the content and style to be very enjoyable, and would encourage me to ask questions where previously I might not have paid much attention, eg. pom version numbers / spring starters being imported. The focus on the different styles of unit testing was also excellent and I would plan to incorporate in day to day work.

Edward K

Instructor was beyond phenomenal. He had an in depth knowledge of the course material and always ensured that everyone understood what was being discussed. I really enjoyed the mix of theory and practical examples of each part of the course.
