Question

When I attempt to access a File object in Java using Eclipse, the system sends a FileNotFoundException whenever the file is accessed. I have created the file manually and placed it within Eclipse’s file browser. The file does have content, so the problem isn’t that it’s empty. I am initializing the File with

File file = new File(this.getClass().getResource("save.txt").toString());

and accessing it with

PrintWriter p = new PrintWriter(file);

which sends the error. The stacktrace flows back through nothing except a path of initializations that create this class. The exception is

java.io.FileNotFoundException: file:\C:\Users\Nathaniel\Downloads\ERPGE-Global%20Equestria%20Workspace\Swarm\bin\main\save.txt (The filename, directory name, or volume label syntax is incorrect)

What could be causing this error, and how can it be fixed?

Answer 1

Provide the actual path to the file and get the file Object. Then you can use it.

File file = new File("C:\Users\Nathaniel\Downloads\save.txt");
PrintWriter p = new PrintWriter(file);

EDIT:

Externalising the File Name:

Create a properties file filedetails.properties in the external folder/package.

fileName=C:\Users\Nathaniel\Downloads\save.txt

Accessing the resource bundle.

ResourceBundle b=ResourceBundle.getBundle("external.filedetails") ;
String fileName=b.getString("fileName");
File file=new File(fileName);
