Road to Java Engineer Part1 Introduction & Environment Construction

Good evening. Is it autumn around Kanto today? It was quiet enough to say. It's easy to spend and study progresses. And if you look at the calendar, it's already mid-July. I am surprised.

I've been developing applications in Rails so far.

I was planning to learn Java and Python for employment in the future "Even if you do more than one suddenly, you will get a flat tire ..." So I decided to concentrate on Java and study.

The reason is ① Being one of the most used languages (2) Because it is said to be more difficult than Ruby Can be mentioned.

First of all, I want to acquire the contents of the Basic Information Technology Engineer Examination and the basics of Java by the time I get a job! I'll do it by saying that!

Learning plan (Proceed as much as possible before getting a job)

--Dot installation Java for the first time --Dot installation Java8 introduction --Purchase of books or Udemy --Personal application development (If employment is decided, work will be prioritized ...!)

Goal (by April)

――Being a Java engineer with basic skills --Passing the Basic Information Technology Engineer Examination in October

At first, I will write it as a personal diary, but I hope that one year later, it will be a series that will be helpful for those who want to become Java engineers! !!

Environment

That's why the first step is to build the environment.

① Access the following site https://www.oracle.com/java/technologies/javase-downloads.html

② Click JDK Download in the center of the following page Image from Gyazo

③ Click Mac OS Installer and follow the on-screen instructions to complete the installation. Image from Gyazo

④ You will be able to execute Java with the following commands!

javac Myapp.java && java Myapp

I'm looking forward to the code after a long time.
