What you’ll learn

  • Understand the new features in Java 9
  • Be able to use the new features in their own projects

Do you know some Java, but worry that with the recent release of Java 9, your skills are now outdated?

Maybe you are a programmer in another language, but want to improve your career prospects by learning about Java 9?

Perhaps you know Java 8 well, and want to find out about the new features in Java 9 so you can put them to use as quickly as possible?

Whatever the reason, if you want to find out about the new features in Java that are relevant to the majority of Java developers, then this course is for you.

The goal of the course was not to simply go quickly through all the new features in Java 9 at a very high-level. Nor was the goal to get into such detail that we forget about the feature we are studying. 

Instead, the course was designed to help you really understand these new features.  

So, we’ll look at what motivated the changes in Java 9 so we can better understand why there are needed and what issues they address.

Then simple, but relevant examples are provided to demonstrate each feature.

Your instructor in this course is Frank Mitropoulos Ph.D, a university professor with over 23 years of software development teaching experience.

What are some of the new features in Java 9?

Among the many new features in Java 9 are the Java Shell, The Java Platform Module System, and updates to the Process API.

In this course we’ll look at the Java Shell in detail. 

We think you will love the Java shell! It makes learning Java, exploring APIs, and experimenting with Java code so much easier and very productive. 

Once you start using it, we think you will go back to it over and over again when you have to write small snippets of code and especially when you are learning a new concept.

The Java Platform Module System is probably the feature that most developers have heard about when they think about Java 9. 

The Java 9 Platform Module System allows Java to move forward  by modularizing the JDK as well as adding modules as first class citizens to Java. 

The module system is actually quite intuitive and we think you will understand it and appreciate its impact straight away.

In this course we explain the motivation and goals for the module system and  then we look at every detail. Along the way we create a modular JokeServer application that we take from not using modules at all, all the way through being completely modularized and having a JavaFX front end.

Finally, we discuss some of the issues you may have when migrating existing non-modular code in Java 9 and we walk through a simple example.

Another exciting addition to Java 9 are the updates to the Process API.

The Process API allows developers to work with native processes directly in Java code.

No more hacky code and no more Java Native Interface code is needed to do things that were previously impossible to do directly in Java. 

In this course we look at the main use-cases where the Process API can be used and show live code examples right in the Java shell. You won’t believe how easy we can now work with processes on any OS.

That’s just an example of some of the content of What’s New in Java 9.

    I can definitely see this course helping breaking through that initial barrier when it comes to learning a programming language. I’m positive I’ll finish it and hopefully master python by then.

  2. Abdallah Galal Abouhussein

    I would like to share my personnel experience, i`m very pleased and happy for taking this impressive course because Dr. Angela always makes it simple and easy to understand and always makes a precaution section before or after any bug that may appear to some students and also write or record the solution for us, and each word she said is very real and easy to understand.
    Thanks Dr. Angela

    Very good course. Dr Angela explains things very clearly. The exercises are interactive and helpful.

    Angela’s voice is like ASMR in most lessons. So you won’t lose focus?

  4. Jaime Sánchez Blanco

    Every concept is very well explained so you can assimilate it, and the teacher insists in practicing daily to get the habit of programming. It really motivates to keep studying and practicing every day.

  5. Bradley Carouthers

    3 days in and I’ve already learned more than other training programs where I’ve put months in. Her teaching style is both efficient and effective.

    Edit: Now on day 29 and the course has held up my expectations and hopes. The rise in complexity is not too sharp, and every day feels like an accomplishment. Angela takes her time to explain things without rushing, yet is able to pack tons of information in nuggets of time.

    Still recommend supplemental exposure for a more wholesome grasp. Though, this should be quite enough

  6. Tommy Prévost

    Very good course.

    PROs: lots of coding exercises, clear explanations, great examples, adapted to 2021’s reality.

    CONs: past the first 30 lessons, many similar coding hands-on.

  7. Quang Tu

    I love all the lectures and challenges of this course. I finally find myself in love with coding. This is definitely a fun course. Thank you Angela for this great course.

  8. Fortunate Eze

    This course is nothing short of AMAZING. The level of love and sincere desire to see students succeed present in this course is a rare sight. This course is fun, it’s challenging, it’s suspense-filled, it makes you feel good about yourself solving those challenges. You don’t take this course and memorise codes, you take it and you know what you’re doing because you literally do it yourself.

    It couldn’t possibly be any more obvious that Angela brought out her whole heart, time, energy and resources to give us a course that if priced based on it’s value, many of us certainly can’t afford. I mean, she kept advising and encouraging us to keep going, because she knows the road could get bumpy, she made a few jokes and used funny animations so we smile along the way keeping it fun. Why some people can’t see this and would rather subscribe to trying to bend courses to fit their own personal preferences is beyond me, but I guess people will always be people.

    Dear Angela, I cannot speak for everyone but I certainly can speak for myself and I’m saying thank you. The efforts you put into making this course outstanding didn’t go unnoticed.

    Let as many of us as appreciate your efforts make you happy and energize you to create more life changing courses for us.

    Just the course fits me. Learn by doing, it is easy to start and just follow the flow and at day 15 you realized how to program in Python. Then the magic happen. I am on day 27 and I am looking forward to start a new section everyday.

  10. Caspar Cheng

    Angela is my favourite teacher on Udemy, her courses always come with clear and concise demonstration, make it really easy to understand the content. Meanwhile, she also provide a lot of tips to encourage us moving further on the way of coding. I’m definitely a super fan of her. I had finished her web development boot camp and now I’m learning Python 100 days of code. This course is amazing as she provided one particular project for each day’s learning, which is, really useful and handy. Also, those projects are really interesting and won’t let me feel disappointed about myself. Although some of them are a little bit difficult, they’re still resolvable after some struggling and searching online. I’ll recommend this course for those who really want to learn Python well and write real python projects from scratch!

  11. Jonas Weber

    The course was awesome in the first half! Really helped me to get back to programming and learning new techniques. Also the course got way to much focused on web development in the second half, which I’m not really interested in and is redundand to your dedicated web development course. The lack of videos in the last quarter was rather sad. I really would’ve liked some video explanations for pandas and matplotlib. The challenges and capstone projects were great and challenging!
    All in all I can really recommend this course for beginners and those who want to learn python and/or get back to programming!

  12. Rohit Prasad

    Angela is the best teacher I have ever experienced. The way she explains all the topics and makes use of it in the projects is commendable. Thank you so much Angela for this course.
