Ok, I'm confused with your code. Why do you ask for the password to the backup when FileNotFound Exception is thrown? Also, the reason yeet1 cant be found is because of scope.

Code java:

---

Scanner yeet1=new Scanner(System.in);

---

This is in your try statement. However, you are trying to use this variable in your catch statement:

Code java:

---

String yeet3=yeet1.nextLine();
...
yeet3=yeet1.nextLine();

---

That cannot be done. Either you need to declare yeet1 before the try/catch statement (and you can still initialize it inside the try statement), or you have to recreate the yeet1 variable inside the catch statement.
