How to create a file in java that works when compiled into a jar? I have a code that creates a file that work in netbeans but not when compiled in Jar

I have a java code that automatically create a file for the user after login. It works properly when I run it in netbeans/intellij. However when I compiled it into a jar file, the program works but the file is not created. Can someone please help me?

Here is my code:

private void createTxtFile(){ String loc = new File("").getAbsolutePath(); String dir = loc+"/src/lists/"+user+"-"+pass+".txt"; try { File myObj = new File(dir); if (myObj.createNewFile()) { System.out.println("File created: " + myObj.getName()); } else { JOptionPane.showMessageDialog(this, "User already have an existing list file."); } } catch (IOException e) { JOptionPane.showMessageDialog(this, "An error occured in creating file for your list.", "Error",JOptionPane.ERROR_MESSAGE); } }
