Working in an interactive learning environment, led by our expert facilitator, you’ll learn to:

  • Understand the fundamentals of the Java platform, its lifecycle, and the responsibilities of the Java Virtual Machine (JVM), enabling you to create efficient and reliable Java applications.
  • Gain proficiency in using the JDK, including navigating its file structure, utilizing the command-line compiler, and executing Java applications, ensuring a smooth development process.
  • Master the IDE, including its interface, project management, and module creation, to enhance productivity, collaboration, and overall development workflow.
  • Develop solid skills in writing Java classes, defining instance variables, creating object instances, and implementing main methods, forming a strong foundation in Java programming.
  • Acquire expertise in adding methods to Java classes, writing constructors, and leveraging the 'this' keyword, allowing you to create more sophisticated and customizable Java applications.
  • Comprehend and apply core object-oriented programming concepts, such as encapsulation, inheritance, and polymorphism, to create modular, maintainable, and reusable code.
  • Enhance your knowledge of Java language statements, including arithmetic, comparison, and logical operators, as well as loops and switch expressions, to develop more complex and efficient Java applications.
  • Learn to effectively handle exceptions, create custom exception classes, and use try/catch blocks to ensure the robustness and reliability of your Java applications, minimizing potential runtime issues.
  • 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.

Specific Java 17 features that are covered in the course include:

  • Switch Expressions
  • Text blocks
  • Pattern matching for instanceof
  • Introduce records as carrier of immutable data

Specific Java 21 features that are covered in the course include:
