javac is not working. error: file not found: Sum.java always pops up when i want to compile the program. Can anyone help me with this?
If you are encountering the "file not found" error when trying to compile a Java program with javac
, it indicates that the Java compiler cannot locate the specified Java source file. Here are a few steps to troubleshoot and resolve the issue:
Verify the file location: Double-check that the Java source file (
Sum.java
) is located in the directory from which you are running thejavac
command. Ensure that the file name is spelled correctly and that the file extension is.java
.Navigate to the correct directory: Open a command prompt or terminal and navigate to the directory where the
Sum.java
file is located. Use thecd
command to change directories. For example, if the file is located in theC:\projects
directory, run the following command:shellcd C:\projects
Check the command syntax: Make sure you are using the correct syntax to invoke the
javac
command. The basic syntax is as follows:shelljavac YourJavaFile.java
Replace
YourJavaFile
with the actual name of your Java source file (Sum
in your case). Ensure that you are typing the command correctly, including proper capitalization and file extensions.Verify Java installation: Confirm that you have installed the Java Development Kit (JDK) on your system. Open a command prompt or terminal and run the following command to check the Java version:
shelljava -version
If you see the version information, it means Java is installed correctly. Otherwise, you need to install the JDK from the official Oracle website.
Check environment variables: Ensure that the Java installation directory is correctly set in the system's PATH environment variable. Open a command prompt or terminal and run the following command to check if the
java
andjavac
commands are recognized:shelljava -version
javac -version
If any of the commands are not recognized, you may need to add the Java installation directory (e.g.,
C:\Program Files\Java\jdk1.x.x_x\bin
) to the PATH environment variable.
By following these steps, you should be able to troubleshoot and resolve the "file not found" error when using javac
to compile your Java program. Make sure the Java source file is located in the correct directory, navigate to the appropriate directory in the command prompt, and check your Java installation and environment variables.
