How to Run Java Programs With Command Prompt (cmd) and Notepad in Windows

How do you compile and execute your Java programs from the command prompt (cmd) in Windows? Also, how you can you write your programs just using Notepad?
We'll go over how to write a Java program in Notepad, then how you can compile and run that program directly from the command prompt (cmd) in Windows.
The video shows Windows 11, but the same process works for Windows 10 or other version of Windows.
This is a great beginner's Java video if you're learning how to execute your programs, or if you're used to using an IDE like Eclipse, and want to learn how to use the command prompt (cmd) instead.

John, you're simply the best. All the tutorials from my university never seemed to work for me until I watched your video following all your detailed steps. Thanks for making me run my first java program and making it feel so simple.

[@dikshyakafle5530]

Thank you John, you're the best. I had an assignment to run a program in command prompt and I continuously got errors. Finally, I understood it.

[@nird4897]

Great video! It worked! My programming professor told me to try using cmd to run our java project, and I kept on getting errors until I watched your video. Thanks a lot!

[@nird4897]

And in addition, I searched for the same question few weeks ago here on TH-cam and no one was able to help me like you did. Definitely worth subscribing! 😁

[@ironman......]

[@franz2027]

Hi John, thank you very much for your videos.
You have the best Java learning channel that I have come across. I've been using your channel to review my Java knowledge after not coding in java for 3+ years and preparing for a Fang interview. I'm also planning to do a talk on it and referencing anybody who wants to learn Java to you.
My request is: "Will you please do a video on Lambdas?"

[@lisatorres2234]

You just taught me something I needed for class. Thank you so much.

[@JJJJ-gl2uf]

I'm here because my OOP exam requires us to do our hands-on exam on notepad. Lezz goooo

[@pradeepa1612]

thank you so much....

[@electronoob7341]

lol! First thing our old-school Java Profs at Uni taught us, they insisted we only use notepad++ and compile & run our code just like this in cmd, no IDE's allowed. Looking back now I must say this is a great way to learn by forcing you to remember and know how to do thing IDE's usually do fòr us these days.

[@upholdjustice372]

Can you show us if there's a way to view the bytecode and machine code of our Java Program as well? Thanks!

[@aljei9146]

Hi, John. Thank you for this tutorial, really helped me a lot. Question though, what if I have multiple classes?? How do I compile and run it in the cmd? Or is it even possible?

[@tiagomuniz1043]

I have the same question...

[@suknayateluguworld1012]

[@PixelBread01]

[@anas8296]

Does the class name and the java file name have to be the same?

[@user-xr7gz7cm9u]

hey i have done the things u said but in cmd i have a issue that i have given cd desktop and enter then it us giving that C:\Users\endg3>cd Desktop
The system cannot find the path specified. how to solve this.

[@gabfuwak]

Hello, i have an issue, i have multiple classes in a project, they also use imports. This method does not support that and i can't seem to find any documentation on compiling a full java project in the command line. Do you have any clue on this?

[@jop4846]

amazing. i feel like i can create any app soon.😅

[@Kakashi-rx5yc]

I am getting this error: Could not find or load main class Demo
Caused by: java.lang.ClassNotFoundException: Demo

[@wiljohndavebaydo]

After the { how do you click enter that starts on the 2nd line and not in the first line below?

[@PhilippexvoliLoL]

so. clear. :DDDD thanks

[@a99g]

When I interd "cd Desktop" it says
"The system cannot find the path specified"
Any clue why?
Edit: Problem solved, I just did a right click one the .java file and choose open in terminal.

[@leodachad260]

Hey John, on my side I can't find my file when I enter cd documents and dir.
What should I do?
