How to Run Java Programs With Command Prompt (cmd) and Notepad in Windows
HTML-код
- Опубликовано: 26 авг 2024
- 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.
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!
And in addition, I searched for the same question few weeks ago here on RUclips and no one was able to help me like you did. Definitely worth subscribing! 😁
Yes absolutely this vedio helped me a lot...
Thank you👍
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.
Now try with packages. 1 hour of googling and the java command still doesn't find my class declaration, in the same exact folder
Same situation here😢
I attend my college lectures of java but didn't understand anything but by watching your single video I got know the basics of java thank you sir ❤
I am so thankful for this. This saved my life. As a beginner, I was losing my mind
Thank you so much my school couldn't teach me that in a month you just did it in a minute
So relatable 😂❤
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?"
So simple and to the point without any unnecessary hassles! Thank you!
Thanks big dog, I appreciate content creators such as yourself. You dove straight into the point with great information. Much love ❤
I learnt a lot from your videos in past 24 hrs.
Thank you sir for sharing such videos.
Thank you very much sir, amazing video ,helped me a biology student who once had no knowledge on computer science,c, java and now I am praised by my java teacher during lab sessions. Once again
Thank you a lot
Thank u so much 🙏🙏 I watched so many videos but didn't get it to run Java in CMD...ur video helped me a lot...❤
Amazing clear and concise tutorial man thank you
Thank you so much John, I've been searching how to do for so long.

You just taught me something I needed for class. Thank you so much.
Thanks sir for providing the wonderful commands previously i had to run task build java then click on run button it was too time consuming but its so simple.....
Great video. I just started a Java course on Moodle and your explanation here helped a lot. Will be following you in future. Many thanks.
I'm here because my OOP exam requires us to do our hands-on exam on notepad. Lezz goooo
I am getting this error: Could not find or load main class Demo
Caused by: java.lang.ClassNotFoundException: Demo
In Linux we use gedit to open the file from terminal, what is it's windows equivalent?

Nice tutorial although I have an src folder with multiple packages and I need the classes from each package to be compiled into the target folder and need to run the driver class from the target folder. Is there a video on this? Thanks
I would've added command line arguments to the tutorial as this is the best way to demo them!
Thank you so much!!!! Headache gone 😅
So simple, but very needed, thx
John, I couldn't help but notice your barebones dash DOES include The Binding of Isaac. Great game choice!
Thank you so muchh brother, It worked after watching a lot of videos...

Thanku so much sir . Your video is really helpful for me you can simply teach us how I can use cmd. Once again thanku so much ❤❤❤❤❤
Best Java tutorial, i was stoped cause i always use javac and dont get any output :( im trying to study java alone haha im from python code, same way, at cmd, and there is a special way to do it, here at the same but diferent way you need to compile and then run it, thanks you for this tutorial, now let the java training start !!
John, you are the best and thank you so much it really worked
THANKS TO YOU SIR MY CODE FINAALY RUN THANK YOU SO MUCH!
thanks for explaining in detail
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.
Awesome classes has always. Also, Binding of Isaac! YES
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.
Hey I got an error on javac ..that is javac is not recognised then what I want to do
do you have JDK installed on your system? if so, do you have the right ENV variables? like JAVA_HOME?
John i ran mind but it keeps shoein Java is not recognize as an internal or external command what do i do?
same
You need to install Java, preferably as a JDK
Thank you, big fan out here!!
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.
Please explain that again I'm having the same issue
Amazing video John.. thank you !!!

Thanks. Extremly good explained
Thanks.This really helped me out
Thank you! This was very helpful👍
You just saved my life thank you

Sir in my command prompt it is showing that the system cannot find the path specified while i entered cd Desktop
Then you have to cd to something else first if you go to your laptop file you can see what is before your desktop . For me I had to cd OneDrive before desktop
@@THEREALBILL03I did what you said. My program ran successfully. Thank you bro. First i didn't entered onedrive Location. Now I understand
am actually intrested in creating an app using java language
Jhon I'm getting error it says file not found what shall I do
Thank you sir!
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?
I have the same question...
i am using windows 7 and when i type "javac myProgram" the command line says: javac is not recognized as an internal or external command. knowing that i have java installed when i typed "java version". What could be the problem?
i use win11 and this is happening to me too
Why in my commant prompt it is showing the system cannot find the path specified ❓❓❓❓❓❓
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?
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.
thanks! that was really helpful!
Simply explanation
Hey John, on my side I can't find my file when I enter cd documents and dir.
What should I do?
Thank you sooo much for helping out
Very Nice teach 👍🏻
Maaan!!.. you are the best
Not using Hello World for your initial test file is heresy!
Thank you so much 😊
Awesome channel, could you do a video about stack and heap memory?
Ohhh myy godd. It finally worked. Thankyou!!
how do i make this code in my notepad automatically create a space, thanks!
John can you please do some search algorithms and more sorting videos, thank you
Amazing tutorial
thank you sir , It helped alot
Thankyou sir this was very helpfull
Thanks my friend
Thanks it's working!!
Why cant I find anything when I search for it in my command prompt. I write "cd Desktop" and it just says they cant find it
what does error: Class names, 'AmongUsJava.Java', are only accepted if annotation processing is explicitly requested
1 error mean
from the background bro looks like musician
Why var, const, let , console.log() are giving giving error name/command not found.
Are you writing JavaScript code instead of Java code? They have similar names but are very different things.
Thank you john
hi I am an idiot. I installed JDK-20 (C:\Program Files\Java)
I tried many times and I cannot see the version when I type (java ~version) on dos cmd.
please help me.
I need to learn programming.. i am trying to pass my degree.
1:07
I am stuck here.
Just to make sure, it's "java -version", not "Java ~version"
I did this and javac compiled the program and makes a .class file but I cant run it. Java command keeps saying it cant find it
Can you show us if there's a way to view the bytecode and machine code of our Java Program as well? Thanks!
Bro, you are awesome.
Thank you sir❤
