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.

[@soul_conscious]

So simple and to the point without any unnecessary hassles! Thank you!

[@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?"

[@clairejing1958]

Thank you so much John, I've been searching how to do for so long.

[@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]

[@vargo2987]

Thank you

[@anas8296]

Thanks for you effort, Does the class name and the java file name have to be the same?

[@pradeepa1612]

thank you so much....

[@manelpuraprasanna7028]

thank you sir

[@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.

[@salmasaffir624]

شكرا 💙

[@mohammedhishampc8487]

thanks man

[@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...

[@parjanyamakeryt528]

Thnq sooooooo much sirrr

[@shirousensei5356]

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

[@jop4846]

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

[@shivpratapsingh2943]

Hi john could you please create a video on Streams api in java

[@PixelBread01]

yhank you my guy

[@o0.jc.0o26]

Thanks for this video.. What if I have multiple classes for one program in separated files and one of them has the main method? How would I just do that for running the program? Thx Edit: i just came up with the solution. The question is that the .java files are included in a package, so in order to run the program in cmd, you must be located in the father folder of the package, and then run it typing java packageName.Main where Main is the .java file containing the main method.

[@user-om3yv2qe9x]

amazing explanation thank you .

[@murewaajala445]

Could not find or load main class helloworld Caused by: java.lang.ClassNotFoundException: helloworld mine is showing this error please what can i do

[@kaosdavy8702]

which jdk are we supposed to download

[@nakushavlog]

Plz share without path set run program on cmd by c drive

[@wiljohndavebaydo]

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