Java 8 Features Repository

Welcome to the Java 8 Features Repository! This repository serves as a guide to the key features introduced in Java 8, with notes and programs provided for a practical understanding of each concept.

Key Features

Lambda Expressions

  • Enable functional programming.
  • Provide a concise way to represent anonymous functions.

Functional Interfaces

  • Interfaces with a single abstract method (SAM).
  • Examples include Runnable, Callable, and Comparator.

Method References

  • A shorthand notation of a lambda expression to call a method.
  • Syntax: ClassName::methodName.

Constructor References

  • Used to refer to a constructor without instantiating the class explicitly.
  • Syntax: ClassName::new.

Stream API

  • Provides a functional approach to processing collections of data.
  • Supports operations like filter, map, and reduce.

Local Date and Time API

  • Introduces new classes for handling dates and times, such as LocalDate, LocalTime, and LocalDateTime.

Feel free to explore the repository and enhance your knowledge of Java 8 features!
