Steps to Install SDKMAN on Ubuntu

Step 1: Open a Terminal

Access your terminal by pressing Ctrl + Alt + T on your keyboard or by searching for ‘Terminal’ in your system’s application launcher.

Step 2: Download and Install SDKMAN

Enter the following command in your terminal to download and execute the SDKMAN installation script:

sdk update

Followed by:

sdk upgrade

These commands will update the SDKMAN tool itself and then upgrade any SDKs you have installed to their latest versions.

Conclusion

SDKMAN! is a strong but easy tool for managing multiple software development kits on Ubuntu. It makes the process simple and boosts productivity. By following this guide, you’ll be ready to manage different SDK versions easily, letting you focus more on coding and less on setting up your environment. Happy coding!
