1 - Introduction to Java 8 New Features
Java 8 introduced several new features and enhancements that aimed to improve developer productivity and code readability.
2) Lambdas and Functional Interfaces
Lambdas allow for more concise code by enabling functional style programming in Java.
Functional interfaces provide a single abstract method that is used to implement lambda expressions.
3) Stream API
Streams provide a new way to work with collections in a functional style, allowing developers to perform aggregate operations on elements easily.
4) Default Methods
Java 8 introduced default methods in interfaces, allowing developers to add new methods to interfaces without breaking existing implementations.
5) Method References
Method references provide a way to refer to methods or constructors without invoking them, simplifying code and enhancing readability.
6) Optional Class
The Optional class was introduced to help avoid null pointer exceptions by explicitly indicating when a value may be absent.
7) Functional Interfaces
Functional interfaces are interfaces that contain exactly one abstract method and are used to implement lambda expressions.
8) Date and Time API
The new Date and Time API introduced in Java 8 provides improved date and time handling, making it easier to work with dates and times in applications.
9) Static and Default Methods in Interfaces
Java 8 allowed the inclusion of static and default methods in interfaces, enabling developers to add utility methods to interfaces.
10) Completable Futures
Java 8 introduced the Completable Futures API, which facilitates asynchronous programming and handling of tasks that may take a long time to complete.
11) Parallel Array Sorting
Java 8 introduced parallel array sorting, allowing developers to take advantage of multiple cores for faster sorting of large arrays.
12) Functional Programming Concepts
Java 8 brought functional programming concepts like higher order functions, immutability, and declarative programming to the Java language.
13) Effectiveness of Java 8 Features
Java 8 features have proven to be effective in improving code quality, performance, and developer productivity.
14) Training Program Overview
