When I am trying to compile a file.java by "javac" command, it gives me "file not found" error, though I have done the path and variable of JDK
If you are encountering a "file not found" error when trying to compile a Java file using the javac
command, even though you have correctly set the PATH and JAVA_HOME variables, consider the following steps to troubleshoot the issue:
Check file path and name: Verify that you are providing the correct file path and name when executing the
javac
command. Ensure that the file exists in the specified location and that the path and file name are correctly typed.Verify file extension: Ensure that the file you are trying to compile has the
.java
file extension. Thejavac
command is specifically for compiling Java source files, so make sure the file you're attempting to compile matches this requirement.Check working directory: Ensure that you are executing the
javac
command from the correct working directory, where the Java file is located. If the file is in a different directory, you need to provide the appropriate relative or absolute file path tojavac
.Confirm JDK installation: Double-check that you have correctly installed the Java Development Kit (JDK) on your system. Verify that the JDK installation directory contains the necessary files and folders, including the
javac
compiler executable.Verify PATH and JAVA_HOME: Ensure that you have correctly set the PATH and JAVA_HOME environment variables.
PATH: Add the JDK's
bin
directory to the PATH environment variable. For example,C:\Program Files\Java\jdk1.8.0_291\bin
for JDK 8. Ensure that you have restarted the Command Prompt after modifying the PATH variable for the changes to take effect.JAVA_HOME: Set the JAVA_HOME environment variable to the JDK installation directory. For example,
C:\Program Files\Java\jdk1.8.0_291
. This variable is not required for compiling Java files usingjavac
, but some build tools and development environments rely on it.
Try absolute file path: As a troubleshooting step, try providing the absolute file path to the
javac
command. This helps ensure that the file can be located regardless of the working directory. For example:luajavac C:\path\to\your\file.java
By following these steps, you should be able to troubleshoot and resolve the "file not found" error when using the javac
command to compile a Java file.
