Java 8 introduced key features like lambda expressions for functional programming, the Stream API for data processing, and the new Date and Time API. Java 9 brought the Java Platform Module System (JPMS) for modular applications, along with JShell for interactive coding. Java 11, as a Long-Term Support (LTS) release, added enhancements like the HTTP Client API, improved String methods, and the var keyword for lambda expressions. Together, these versions transformed Java, boosting productivity, performance, and flexibility.
Yes, basic knowledge of Java fundamentals (syntax, classes, and objects) is beneficial, as this course focuses on features introduced in Java 8, 9, and 11. Familiarity with previous Java versions will help, but the course typically covers the essentials needed to get started.
These features significantly improve code readability, maintainability, and performance. For example, lambda expressions and the Stream API in Java 8 simplify data processing, while Java 9’s modules improve code structure, and Java 11’s HTTP Client API facilitates HTTP requests, making your code more efficient and modern.
