Hi Everyone,

In this Java 8 course, I tried to keep only practical things and mainly focused on Lambda & Stream API along with Date.

New features and improvements in Java 8.  Understanding all the new features from eight versions is made easier by taking the Zero to Hero course. All of the new features will be thoroughly covered in this course, both in terms of theory and code. All of the key features, including:

  • Lambda Expressions,

  • Streams API is one of the important features that got introduced as part of Java8.

  • How does the Stream API Works with example

  • max()

  • min()

  • limit()

  • sort()

  • File Reading with all techniques

  • File Writing along with CSV file Reading

  • How Collections are different from Streams

  • Date & Time,

  • Default & Static methods,

  • Optional, Method References

  • This section covers how to perform Parallel processing using Streams.

  • How to check the performance between the sequential and parallel programming

  • Functional Interfaces have received special consideration and explanation. Each feature will be covered during the course discussion with a conceptual explanation first, followed by a thorough code walkthrough and execution. Since the course is set up so that omitting a known feature won’t affect other parts or lectures, you are free to skip any features that you are already familiar with.

  • JavaScript Calling from Java 8

  • Java 18 feature: Embedded WebServer and how to use it.
