How To Install SDKMAN on Fedora 38

In this short tutorial we will learn how to install Sdkman on Fedora 38 operating system.

Introduction

Managing multiple software development kits (SDKs) and build tools for different programming languages can be a cumbersome task, especially for developers who work with various technologies. SDKMAN! (Software Development Kit Manager) is a valuable open-source tool designed to streamline the process of installing, managing, and switching between different SDKs and tools. In this article, we’ll explore SDKMAN! and how it simplifies the development environment for developers.

What is SDKMAN ?

SDKMAN! is a command-line tool that provides a convenient and consistent way to install, manage, and switch between various SDKs, runtime environments, and build tools. It primarily focuses on technologies used in the Java ecosystem, but it also supports several other programming languages and tools, making it versatile for developers working on different projects.
