Homebrew Install Java 8: A Comprehensive Guide

When it comes to managing and switching between different versions of Java on your macOS machine, using a reliable environment manager can be a game-changer. In this article, we'll delve into the world of jenv, a popular tool that allows you to install, manage, and switch between various JDK versions, including OpenJDK 8.

Prerequisites

Before getting started, ensure that you have Homebrew installed on your system. If not, you can download it from the official website and follow the installation instructions.

Installing OpenJDK 8 using Brew

OpenJDK 8 is only compatible with Intel x86_64 architecture, so if you're running an ARM M1/2 chip, you'll encounter an error when trying to install. To install OpenJDK 8 using Homebrew, run the following command:

```

brew install openjdk8

```

Understanding jenv

jenv is a powerful tool that provides several benefits, including:

* Sets `JAVA_HOME` inside your shell, allowing you to configure it globally, locally, or per-shell.

* Enables you to switch between different Java versions.

With jenv, you can easily manage and switch between various JDK versions, making it an essential tool for developers working on Android applications, which often require Java 8, as well as server applications that use later versions like Java 11.

Manual Install of Java (Early-Access Builds)

If you're looking to install early-access builds of Java, such as JDK 16, you can do so manually. However, please note that these builds may not be stable and are intended for testing purposes only.

Configure JAVA_HOME with the Default Version of Java

To configure `JAVA_HOME` in your shell using jenv, you'll need to specify the default version of Java. You can do this by running:

```

brew install -cask temurin11

```

This will install Temurin 11, a popular Java runtime environment.

In this article, we've explored the world of jenv and how it can help you manage and switch between different versions of Java on your macOS machine. Whether you're developing Android applications or working with server-side projects, jenv is an essential tool that can simplify your workflow and make managing Java versions a breeze.
