These are the best free courses to help you learn Java 8 and Java 9
这些是帮助你学习Java 8和Java 9的最佳 免费课程
After the introduction of the six-month release cycle on Java 10, it’s very difficult to keep up with the latest changes in every Java version. But If you’re looking for some free resources on Java, such as books, tutorials, and other learning materials, then you have come to the right place.
在java10的发布周期为六个月之后,很难跟上最近在每个java版本的改变。但是如果你寻找一些java的免费资源,例如书籍,教程,其他学习资源,那么你就来对地方了。
There are so many resources available to master the features that were introduced in Java 8 and Java 9.
In the past, I have shared some of the best Java 8 tutorials and books. In this article, I am going to share some of the best and free Java 8 and Java 9 courses from Udemy and Pluarlsight.
这里有很多的资源可以用来掌握java8 和java9中介绍的内容
在以前,我曾经分享过一些比较好的关于java8的教程和书籍。在这篇文章中,我讲去分享一些来自于Udemy和Pluarlsight中的比较好的而且免费的java8和java9的课程。
These courses are pretty similar to any paid course you might normally buy and many of these are made free for a promotional or educational purpose. You can join these courses to learn JDK 8 and JDK 9 features in just a couple of days.
这些课程与您通常可以购买的任何付费课程非常相似,并且其中许多是免费的,用于促销或教育目的。 您可以参加这些课程,以在短短几天内学习JDK 8和JDK 9功能。
I used to begin learning new programming features with books, but, nowadays, online courses are my preferred method of learning. There are so many good free courses available.
我曾经从书本上开始学习新的编程知识,但是现在呢,在线课程是我最喜欢的学习方式,有很多好的免费的课程。
Though, sometimes, I have noticed that free courses turn into paid courses, especially after the instructor reaches their promotional targets, hence you should check the price before you join these courses.
虽然有时我注意到免费课程变成了付费课程,尤其是在讲师达到其促销目标之后,因此您应该在加入这些课程之前检查价格
A good idea is to join the courses now, while they are free. Once you are enrolled in the course, you will have free, unlimited access, even after it is turned into a paid course. This means that you can learn whenever you want.
一个好的主意就是加入这些课程,现在他们是免费的。一旦你开始报名了这些课程,你将会免费,不受限制的访问,哪怕是之后它变成了付费的课程。这就意味着你可以在你想学习的任何时候学习。
Even if you are not learning now, you can learn more when you have some free time or your priorities change — there is no harm in enrolling.
即使您现在不学习,当你有闲余时间或者你的优先权变化了,您都可以学到更多东西–注册没有害处。
Why should you Learn Java 8 and Java 9?
为什么你应该学习java8和java9?
If you are wondering about the benefit of learning the features of Java 8 and Java 9, then, let me tell you. If you want to be relevant as a Java developer in today’s job market, you should learn Java 8 now.
如果您想了解学习Java 8和Java 9的功能的好处,那么让我告诉您。 如果您想成为当今工作市场中的Java开发人员,请立即学习Java 8。
I have mentioned previously in my post 10 Things Java Developers Should Learn in 2018, and I am saying it again: learn Java 8 sooner rather than later.
我之前在我的文章《 2018年Java开发人员应该学习的十件事》中提到过,我再说一遍:尽早学习Java 8。
It’s been more than four years since Java 8 was first released, and it was received very well by the Java community. It had several interesting features and language enhancements, like lambda expressions, Stream APIs for bulk operations, new Date and Time APIs for better handling of dates, Default and Static methods on the interface, Method reference, and many more.
Nowadays, more and more companies are adopting the Java 8 style of coding. If you don’t know write code in Java 8 style, such as using lambda and functional programming concepts, you may be left behind.
Not only is Java 8 essential to being relevant in the Java community, but it also improves your productivity and makes writing Java code fun, once you know the basics. That’s where these courses can help!
Coming to Java 9, it didn’t have the spark of Java 8. But it was still packed with some interesting features, like modules and some API enchantments. Knowing those features will, eventually, help you write better Java code and create a better application in Java.
自Java 8首次发布至今已有四年多了,它受到Java社区的好评。它具有一些有趣的功能和语言增强功能,例如lambda表达式,用于批量操作的Stream API,用于更好地处理日期的新的Date和Time API,界面上的Default和Static方法,Method reference等。
如今,越来越多的公司采用Java 8风格的编码。如果您不知道以Java 8风格编写代码(例如使用lambda和函数式编程概念),那么您可能会落伍。
一旦知道了基础知识,Java 8不仅对于在Java社区中发挥作用至关重要,而且还可以提高您的工作效率并使Java代码的编写变得有趣。这些课程可以为您提供帮助!
来到Java 9时,它没有Java 8的spark。但是它仍然充满了一些有趣的功能,例如模块和一些API enchantments。最终,了解这些功能将有助于您编写更好的Java代码并使用Java创建更好的应用程序。
