I am truly moved by your comment, @anzilashanavas6066. It's very rewarding to know that our content has had a positive impact on you. This channel is all about helping learners broaden their knowledge in the world of Java programming, and it's comments like yours that motivate us to keep doing what we do. If you have other topics you'd like us to cover in the future, please do let us know. Keep learning and growing!

Thanq for your precious reply. Yes you are correct that we dont need to go to bin. As we all know that there are multiple ways to execute java program. Using IDE solve all problems. And even setting classpath also solve these problems. I tried to explain one way of execution. It will be very helpful if you can guide learners about other ways. Thanq for giving time making learning more efficient.

Techlearners by Neeraj Saxena: Hi @UwU-dx5hu, you're correct and thanks for highlighting it. You do not necessarily have to save and run a Java file from the bin directory. In our video, we just demonstrated one of many ways to compile and execute a Java file. In a more efficient setup, you typically would set your environment variables such that you can run the Java commands from any directory. Thanks again for pointing this out. We appreciate your feedback and will cover these nuances in future lessons.

Hi @veera8591, I love your enthusiasm! You're on the right path with your simple program. I'm glad you picked up the basics of a Java class structure from the tutorial. Keep practicing and you'll be a pro in no time! 😊😊😊

1. Go to control panel and change the user account policy to minimum. Restart your PC. Now you should get permission.
2. Login to your administrator account and run your program then
3. From administrator account give permission to your login account for writing permission to C Drive.
4. You can also use any java IDE like BlueJ or JCreator.

Hi there @ronniebain9776, I can understand how frustrating this issue can be. Luckily, there is a workaround. The issue arises due to Windows 10 administrator rights - And we can simply get around it by running your text editor (Notepad, for instance) as an administrator. First, you close your Notepad and right-click on the icon, then hit the "Run as administrator" option from the dropdown. If prompted, click 'Yes' to allow the app to make changes to your device.

Now, open your Java file and you should be able to save it without the error message. Remember, it's crucial to save in the JDK folder in your C: Drive, as discussed in the video. If you continue to experience difficulties, feel free to ask for help. I'm here to make your learning journey smoother. Happy coding!

Due to permissions in windows.. It may be possible that for user we have not granted file writting permissions..when we compile java program, a class file is written on drive, if our user does not have file writting permission then class file will not be written.. It is agood practice to run admin. Alternatively if we set permission for user we can run it normally. I hope u can understand my explanation, if not then pls feel free to querry again.

Hi @misbahmulla8796, great question! Running as administrator grants the software a higher level of clearance, allowing it to make changes to your system that it wouldn't normally be able to do. While not always necessary for running Java programs, it can help sidestep certain permissions-related issues, particularly when trying to access certain system directories or files. Doing this as a preventive measure ensures smoother operation. I hope that answers your question. Feel free to ask if you've any more queries. Happy Learning!

Thank you so much @ganeshchintala6668! I am incredibly proud and thrilled to know that my tutorial assisted you in executing your first program. Remember, every programmer's journey starts with a single line of code. Keep going and never stop learning. Don't hesitate to reach out if you have any questions. Happy coding!

Make sure that you are saving your file with same name as you class name with java extension. Secondly make sure that you are saving it in same directory where you have javac. please watch the full video carefully.

Hi @vemuryjanakikumari8744, I'm glad to hear that you are enthusiastic about learning coding. That error usually appears when the java file doesn't exist in the location you specified or when the classname is spelled incorrectly.

First ensure that your .java file is in the correct directory, as in the path where you've saved your program. The path is usually 'C:\Program Files\Java\jdk[version number]\bin'. When entering the filename in command prompt, it should appear as 'java program', excluding the .java extension.

Also, Java is case-sensitive, so ensure to save your file with the same class name you provided in your program. For example, if your class name is 'JavaProgram', your file name should also be 'JavaProgram.java' and not 'java program.java'.

Lastly, make sure you are running the java command from the same directory where your .java file is located. If your program is located in the bin folder of the JDK in the C drive, your command prompt should reflect that path.

Kindly check these aspects and rerun your program. I hope this helps and don't worry, programming is all about hitting roadblocks and then overcoming those. Keep going!

There is no error as starting java class with capital letter is not mandatory in java. It will give no error and u can execute the program. Making java class name that starts with capital letter is just a naming practice.

Thank you @kallurishyamsundhar7195 for correctly pointing that out! You're absolutely correct, the class name in Java should start with an uppercase letter as it adheres to the Java naming conventions. This is due to the fact that Java is case sensitive. You've certainly helped highlight an important concept for our beginner Java learners. Be sure to continue your active participation, it's greatly appreciated!

Hi @t.b.f3279, It's great to hear that our tutorial has been helpful to you! Now that you've got the basics of running a Java program down, there's a whole world of coding out there for you to explore. Dive deeper into Java and I promise you, it's going to be an exciting journey. Happy coding! Keep watching and learning.

U can set classpath.. Or store program in same directory where you have javac.. Usually it is inside bin folder.. Please follow the steps explained in the video of execution carefully ..if still u have any problem then do let me know.

Hello @gorlavaishnavi5948, thanks for reaching out! It seems like your Java compiler is unable to find your class file. Please follow these tips to resolve the issue.

1. Make sure the name of your .java file exactly matches the name of your public class. Java is case-sensitive, so all letters should align exactly.

2. Check the directory from which you're trying to run the java command. You should be in the same directory where your .java file resides. In the command prompt, you can use `cd YOUR_DIRECTORY_PATH` to change the directory.

3. If you're using packages, the package statement in your code should align perfectly with the directory structure. If the package statement is `package com.example;` your .java file should be in a directory called com/example.

4. If all else fails, you might want to try using the `-cp` flag to specify the classpath when you compile and run your program. Your command would look like this: `javac -cp . MyClass.java` and to run `java -cp . MyClass`. The -cp . basically tells the JVM to look for classes in the current directory.

I hope this helps. If you're still having trouble, do let me know. Keep Coding!
