Java – how do I use relative paths instead of absolute paths?

So I have a strange question about Java

I'm reading and writing files, so the path is very important to me I want all files to be written and read from relative paths (that is, in the folders of the rest of my classes and java files)

I write this file:

FileWriter fw = new FileWriter(outfile,true);
fw.write(data);
fw.close();

Outfile is like 'out Txt '(that is, the name of the file we want to output into)

The problem is that the file was created in / home / me /, not the path to my other files

Did I do something wrong? Or how can I store files in relevant directories?

Solution

FileWriter fw = new FileWriter("./" + outfile,true);

FileWriter fw = new FileWriter("./" + outfile,true);

or

FileWriter fw = new FileWriter("~/" + outfile,true);

I'll try
