Thread: Java Password Saver Problem

I am working on a simple password saver that makes a text file and then i can add a website username and password, but whenever i try to add new information it says

[COLOR="#FF0000"]Exception in thread "main" java.lang.NullPointerException
at password.createFile.addRecords(createFile.java:32)
at password.apple.main(apple.java:21)[COLOR]

Can anyone help me understand why it does not work?

here is the code
--------------------------------------------------------------------------------------------

package password;
import java.util.*;
 
public class apple {
	public static void main(String[] args){
 
		@SuppressWarnings("resource")
		Scanner input = new Scanner(System.in);
		System.out.print("what would you like to do? 'add' or 'see'?");
		String option = input.nextLine();
 
		if(option.equals("see")){
			readFile r = new readFile(); 
			r.openFile();
			r.readFile();
			r.closeFile();
		}
		if(option.equals("add")){
			createFile g = new createFile();
			//g.openFile();
			g.addRecords();
			g.closeFile();
		}
	}
}

--------------------------------------------------------------------------------------------

package password;
import java.io.File;
import java.io.File.*;
import java.util.*;
 
public class createFile {
 
	public static String web;
	public static String user;
	public static String pass;
	private Formatter y;
	public Scanner x;
 
	public void openFile(){
	try{
		x = new Scanner(new File("test.txt"));
		System.out.println("You crested a file");
	}
	catch(Exception e){
		System.out.println("you have an error");
	}
	}
	public void addRecords(){
		@SuppressWarnings("resource")
		Scanner input = new Scanner(System.in);
		System.out.print("Website: ");
		String web1 = input.nextLine();
		System.out.print("Username: ");
		String user = input.nextLine();
		System.out.print("Password: ");
		String pass = input.nextLine();
		y.format("%s %s %s", web1, user, pass);
	}
 
		public void closeFile(){
			x.close();
		}
 
}

--------------------------------------------------------------------------------------------

package password;
import java.io.*;
import java.util.*;
 
public class readFile {
 
	public Scanner z;
	public static int one = 1;
 
	public void openFile(){
		try{
			z = new Scanner(new File("test.txt"));
		}
		catch(Exception e){
			System.out.println("Could not find file");
		}
	}
 
	public void readFile() {
		if(one == 1){
			String a = z.next(); 
			String b = z.next();
			String c = z.next();
 
			System.out.printf("%s %s %s", a, b, c);
 
		}
	}
		public void closeFile(){
			z.close();
		}	
}

I added the println and they all print, but it is still saying there is an error.

this is what prints:

what would you like to do? 'add' or 'see'?add
