Why Does My Java Code Throw a \'java.io.FileNotFoundException,\' and How Can I Fix It?

Resolving "java.io.FileNotFoundException: the system cannot find the file specified" Error

In Java, the "java.io.FileNotFoundException: the system cannot find the file specified" error occurs when a code attempts to access a file that doesn't exist. Let's delve into the specific case presented to address this issue:

The code attempts to read a file named "word.txt" using a Scanner. However, the message indicates the file wasn't found. To resolve this, ensure the file is located in the same directory as the Java file or adjust the path accordingly.

The reason for this discrepancy lies in the way the Java development environment and Java Virtual Machine (JVM) interact. When working inside an IDE, the "working directory" is typically the project's root folder. Hence, placing "word.txt" at the root level of the project should resolve the issue.

However, it's essential to note that the working directory may differ when running the code from the command line or as a packaged JAR file. In such scenarios, specify the file's path relative to the current working directory or package it as a resource within the JAR.

Alternatively, you could utilize the Class class's getResourceAsStream() or getResource() methods to access files from the classpath if the file is intended as an embedded resource. This method retrieves the file path in the form of an URL.

By following these guidelines, you can effectively resolve the "java.io.FileNotFoundException" error and ensure the correct functioning of your Java code.
