Java Runtime Manager (JRM)

Description

A lightweight Python tool to manage Java installations, because SDKMAN doesn't exist on Windows.

Features

• Detects and sets multiple Java vendors (Oracle, Adoptium, Zulu)
• Updates JAVA_HOME automatically
• Cleans old Java entries from system and user PATHs.
• No additional packages needed

Requirements

• Windows
• Python 3.x
• Administrator privileges to update system variables

Installation & Usage

1. Clone the repository:

   git clone https://github.com/Meolsei/Java-Runtime-Manager.git
   cd Java-Runtime-Manager

2. Run the script as an administrator:

   python main.py

3. Follow the prompts:

   Input Java Version: (8, 11, 17, 21, 25)
   Input Java Vendor: (Adoptium, Oracle, Zulu)
   

The script will update JAVA_HOME and PATH automatically.

Testing

• For PowerShell:

  $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine")
  java -version

• For Command Prompt:

  set PATH=%PATH%;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
