[FIXED] Export Data from Java to a text file

Issue

I want to export the character's name and gender to a text file. Also, I need to export on both Mac and PC computers. I've tried various methods, but none has worked for me or I might have placed them incorrectly.

I changed my code with my attempt:

import java.util.Scanner;
import java.io.PrintWriter;
import java.io.File;
import java.util.Scanner;

public class Character {

    public static void main (String[] args) {
        String characterGender;
        String characterName;

        Scanner scan = new Scanner(System.in);

        System.out.println("Welcome to Ricardo's character creator!");

        System.out.println("Is your character a boy or a girl?");
        characterGender = scan.nextLine();

        if (characterGender.equals("girl"))  {
             System.out.println("Awesome! Please enter her name: ");
             characterName = scan.nextLine();
        } else {
             System.out.println("Awesome! Please enter his name: ");
             characterName = scan.nextLine();
        }

        System.out.print("Alright! " + characterName + " has been created!");

        PrintWriter out = new PrintWriter("Character.txt");
        out.println(characterName);
        out.println(characterGender);
        out.close();

    }
}

I'm getting an error like this:

Character.java:34: error: unreported exception FileNotFoundException; must be caught or declared to be thrown.

Solution

You need to handle the FileNotFoundException. This can be done either by:

Catching the exception (Preferred method):

PrintWriter out;
try {
    out = new PrintWriter("Character.txt");
    out.println(characterName);
    out.println(characterGender);
    out.close();
} catch (FileNotFoundException e) {
    System.err.println("File doesn't exist");
    e.printStackTrace();
}

or by throwing the exception:

public static void main (String[] args) throws FileNotFoundException

Note: import java.io.FileNotFoundException; must be included in both cases.

Here is some java documentation on Exceptions.
