javac -cp src/ {locate your java file}/*.java -d bin 

# Create build folder
mkdir build

# Compile using the .class file and manifest.txt to create a .jar file
jar -cvfm build/{Name of your Jar file}.jar Manifest.txt -C bin/ . src/

# Run MyFile.jar
java -jar build/{Name of your Jar file}.jar

Manifest.txt

Manifest-Version: 1.0
Class-Path: .
Main-Class: com.company.{.java name file}

I actually have java installed on my laptop nut it still says: "The command jar is either misspelled or could not be found." And I couldn't ind any information on how to install it on Windows 10/11. How did you install it or do I have to move it to WSL every time I want to compile it, compile it and then move it back? Also I tried finding a msys2/mingw64 or 32 executeable that could handle it but sadly no luck there.
