Install JDK on Mac OS. Summary

Installation Java

In order for Andorid applications to develop your computer, you need to make a platform from your system for development. Android SDK (developer for Android) was developed using Java programming language. Similarly, android applications are also developed using Java. Therefore, first of all, it is necessary to install JDK. Java itself is also supplied with a set of development (Java Development Kit. Jdk), and with executive (jre) packages. And it is in this article that I will tell you about the installation of Java on Windows, Mac OS X, Linux.

  • Windows Vista (32-bit or 64-bit)
  • Windows 7 (32-bit or 64-bit)
  • Windows 8 / Windows
  • Mac OS X version 10.5.8 or later (only Intel systems)
  • Linux systems from version 2.11 or later version of the library GNU C (Glibc)
  • At least 2 GB of RAM (4 GB is recommended)
  • 1.5 GB of free space on the disk (given the subsequent installation of Android Studio)

NEXT STEP, IS to Move The Extexted Folder to a Place Where Macos Searches for Java JDK:

Now, Check IF You’ve Successfully Installed the JDK with:

Just to be Sure That Erything Works, Try to Compile and Run a Simple Program:

Save the ABOVE as Helloworld.Java and Compile it with:

IF You Want to Run The Compiled Version:

Side Note, You can also Run Directly The Program, Without the Separate Comption Step with:

BUT THIS IS USALLY SLOWER THE COMPILING THE CODE with Javac and Running the Compiled Code.

Managing a few JDK using jenv

Despite the fact that sdkman! convenient for installing JDK, but it does not help with automatic switching between different JDK when moving from one project to another. Jenv will help us here.

After you install a few JDK, using sdkman! Or in any other ways, you will need to add them to Jenv:

Repeat the Jenv Add command for the remaining three JDK versions.

jenv is especially convenient for those who are constantly using the command line. He will allow you:

  • Install the Java version globally for your system.
  • Install the Java version for the current catalog / project in which you are.
  • Install the Java version for the current Shell’a.

Automatic switch between JDK

Now you have installed Java 8, 11, 14 and 15-EA. So how to switch between them? Let’s configure the versions and test switch.

How to Install Java on Mac | Install Java JDK on macOS


First you need to specify the default global jdk in the system. For this, I usually use early assemblies (Early Access). Whenever I start working with a new project, I automatically use the upcoming release, which helps me identify the potential problems that I can report to the Openjdk project. You are doing this too.

Now for any folder in which you are when performing Java.Version You will receive Openjdk 15 EA.

If you have a project that should use Java 8, then go to the folder and run:

As a result, a file called.Java-Version with the following contents:

This file is reported by Jenv, which JDK to use when you are in this folder.

Finally, if you want to temporarily switch to another version of JDK, then use Jenv Shell.

There is a demo here that can explain all of the above and how auto.cutting works.
