Amazon corretto 11 for windows

In this article, I will guide you how to download and install Amazon Corretto JDK (version 8 or 11) on Windows operating system – as an alternative to OpenJDK or Oracle JDK.

1. What is Amazon Corretto?

You know, Amazon Corretto is a no-cost, multiplatform, production-ready distribution of OpenJDK. This JDK distribution is backed by Amazon, with thousands of Amazon Web Services running on Corretto – so it’s highly reliable.

Why programmers and developers should use Amazon Corretto instead of OpenJDK and Oracle JDK out there?

Because it’s FREE for all purposes (including personal and commercial uses) and it has long-term support from Amazon with quarterly updates. Whereas OpenJDK is free without support; and Oracle JDK is not free for commercial use. And Oracle JDK provides long-term support for only paid customers.

So Amazon Corretto is a good replacement for OpenJDK and Oracle JDK. It is licensed under General Public License (GPL) version 2 with Class Path Exception.

As the name implies, Amazon Corretto 8 is built on OpenJDK 8 (Java 1.8) and Corretto 11 is built on OpenJDK 11.

Head to Amazon Corretto homepage, and click the download button according to the version you wish:

For Windows operating system (64-bit), choose to download the installer program (MSI) for JDK:

Then it will download the amazon-corretto-VERSION-windows-x64.msi file. This is the installer program for Windows, which makes the setup process quick and easy.

3. Install Amazon Corretto

Run the downloaded .msi file to start installing Amazon Corretto. You will see the setup program appears:

Click Next, keep the default options presented as below:

You can notice that this installer will setup the JAVA_HOME system environment variable to point to Corretto, and add JDK bin folder path to the PATH system environment variable – very convenient! So you don’t have to manually update those variables after setup.

Then click Next to proceed. Click Finish when the setup completed.

NOTE: You can install Amazon Corretto JDK along with OpenJDK or Oracle JDK, but it will override the JAVA_HOME and PATH system environment variables.

The Java Development Kit (JDK) is a software development environment used for developing Java applications and applets. It is a collection of programming tools, including a Java compiler, a Java Virtual Machine (JVM), a debugger, and other tools and utilities needed to write, test, and debug Java programs.

The JDK is platform-independent and includes tools and libraries for developing, testing, and deploying Java applications across a variety of platforms, including Windows, macOS, and Linux. It also includes documentation and examples to help developers learn how to use the Java programming language and its associated APIs.

What is Amazon Corretto?

Amazon Corretto is a no-cost, multi-platform, production-ready distribution of the Open Java Development Kit (OpenJDK). It includes the Java SE standard libraries and components, such as the Java Virtual Machine (JVM), the Java class libraries, and the Java Development Kit (JDK) tools.

It is mainly built using the OpenJDK source code, and it is tested and certified to be compatible with the Java SE standard. It includes performance enhancements, security fixes, and bug fixes that are contributed to the OpenJDK community by Amazon and other contributors.

Requirements

1. Windows 10 and above
2. A working network connection
3. Administrative permissions

Step 1 — Verify Java is Not Installed

The first step is to verify that you do not have an existing Java installation. Multiple Java JDKs can result in conflicting versions and compilation.

To check if Java is installed, open the command prompt and run the command:

java --version

The command above should return an error indicating that the specified command is not recognized. An example output is as shown below:

java: The term 'java' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

However, the command returns the Java version, then you have the Java JDK already installed on your machine.

Step 2 — Download the Amazon Corretto JDK

The second step is to download the Amazon Corretto JDK from the official downloads page. You can navigate to the link provided below:

On the Downloads Page, locate the installer for your Windows Version and start the download.

We recommend downloading the MSI installer version. If you are looking for a portable version, you can use the provided zip file instead.

Step 3 — Install Java on Windows

Once the download is complete, we can proceed and install Java on your Windows machine.

You can follow the steps as provided below:

Step 1 — Run the Provided Installer

Open the location where you saved the download installer file and open the installer file.

Step 2 — Configure the Installer

On the Welcome section, Click Next to proceed to the next step.

In the next section, choose the features you wish to install on your system and the destination location. For simplicity and maximum compatibility, we advise using the default values and ensure all components are installed.

Once satisfied, Click Next to proceed to the next step and begin the installation. The next step may require admin permissions to configure the installer on your machine.

Click Finish to finalize the setup process of the JDK on Windows.

Step 4 — Verify Java Installation

By default, the Amazon Corretto JDK automatically configures the path to the Java executable. To verify, open the command prompt and run the command:

java --version

In this case, the command should return the installed JDK version and vendor information as shown in the example below:

openjdk 11.0.18 2023-01-17 LTS
OpenJDK Runtime Environment Corretto-11.0.18.10.1 (build 11.0.18+10-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.18.10.1 (build 11.0.18+10-LTS, mixed mode)

Step 5 — Configure the JAVA_HOME Variable

JAVA_HOME is an environment variable that points to the location where Java Development Kit (JDK) or Java Runtime Environment (JRE) is installed on a computer.

When a Java application or tool is run, it looks for JAVA_HOME to determine the location of the JDK or JRE. Setting the JAVA_HOME environment variable ensures that the correct version of Java is used by the application or tool.

On Windows, we can configure the JAVA_HOME environment variable on Windows using the steps below:

Open the Start menu and search for «Environment Variables» and select «Edit the system environment variables».

In the System Properties window, click on the «Environment Variables» button.

In the Environment Variables window, under System Variables, click on the «New» button.

In the New System Variable window, enter JAVA_HOME in the «Variable name» field.

In the «Variable value» field, enter the path to the directory where Amazon Corretto 11 is installed. For example, if you installed Amazon Corretto 11 in the default location, the path should be C:\Program Files\Amazon Corretto\jdk11.0.18_10.

Click «OK» to save the new environment variable.

In the System Properties window, click «OK» to close it.

Restart any applications or tools that require Java, such as command prompt or IDE, to ensure they use the updated JAVA_HOME environment variable.

Step 6 — Write a Test Java Program

Once you have installed Java, it is good to test that the Java compiler is working. You can test it by building the classic hello world program as provided in the instructions below:

Conclusion

In this post, we covered how you can install the Java JDK 11 on Windows 10+ using the Amazon Corretto JDK. We hope this tutorial helped you. Leave us a comment down below to let us know what you think.

This is my first Qiita post in a long time. (This is a rehab post)

Now that you’ve bought a new PC, let’s set it up! I thought,
Since it is a long time, I think that I will write a setup procedure. (in several installments)
This time, we will put «JDK» (Java Development Kit).

JDK, what to make? problem

Which JDK should I use before putting in the JDK? The problem.

I would like to refer to the slide of «@yamadamn» that I announced at the Java event before.

Ms. @yamadamn

これからのJDK/JVM 何を選ぶ？どう選ぶ？ from Takahiro YAMADA

▶ «What will you choose for the JDK/JVM of the future, and how will you choose?»

There are a lot of things…
I was thinking about what I was going to use in my environment, but this time I decided to include Amazon Corretto.

【Amazon Corretto】
https://docs.aws.amazon.com/corretto/index.html

It is multi-platform compatible, and I am thinking of deploying and operating the Java application I made in the AWS environment in the future. When I thought about putting the created app on the AWS environment, I thought that there was no doubt that it would be developed with the JDK that Amazon has put out.
(I also have experience using it in the field, so that is also the decisive factor w)

As of December 2019, there are Amazon Corretto 8 and Amazon Corretto 11, but of course this one is new. Use Amazon Corretto 11.

▶ What is Amazon Corretto 11 https://docs.aws.amazon.com/ja_jp/corretto/latest/corretto-11-ug/what-is-corretto-11.html

< Setup Instructions>
1) Jump to the download link immediately
https://docs.aws.amazon.com/ja_jp/corretto/latest/corretto-11-ug/downloads-list.html

2) Download the Windows version (Linux version and Mac OS version are also available, so be appropriate)
https://d3pxv6yz143wms.cloudfront.net/11.0.3.7.1/amazon-corretto-11.0.3.7.1-1-windows-x64.msi
Once downloaded, install. It’ll be over soon.
After installation, the installed JDK is located directly under the C drive.

3) No need to set system environment variables!
After installation, nothing in particular was required. When I checked the system environment variables, Path was already passed.

4) Check Java version from command prompt
java -version

The version of Java is displayed, so the installation is complete.

Summary

This time I installed Amazon Corretto, but the installation method is almost the same for other OpenJDK and OracleJDK. The working time is exactly «5 minutes!»

Completed the download → installation → setting system environment variables on → download site

I go to various sites at SES, but the first thing I do is «set up the development environment»
I’m a Java engineer, so the language I use in the field is Java. This means that you will always install the JDK every time. I’ve done it many times already… No steps are required.

That’s it all in a flash.
From next time onwards, I would like to go a little further and dig deeper into the technology.

That was the rehab post.
