java password

Can someone make a program that creates a simple 4 digit password for a text file, and notate what every line of code does.

Hello pwngrammer and welcome to the java programming forums. I think this belongs in the java program collaboration section located here: Project Collaboration - Java Programming Forums

I would help you out here but I don't know much about file I/O in java. Sorry :(.

That forum is more for projects that we work on as a team. pwngrammer is just being lazy and asking for someone to do the work for him :-"

Try this pwngrammer:

Code :

---

import java.io.*;
import java.util.Random;
 
public class Pwngrammer {
 
    /**
     * JavaProgrammingForums.com
     */
    public static void main(String[] args) throws Exception {
 
        Random r = new Random();
 
        Writer output = null;
        File file = new File("PasswordFile.txt");
        output = new BufferedWriter(new FileWriter(file));
 
        int password = 0;
 
        for(int a = 0; a < 4; a++){
            password = (int)(9.0 * Math.random()) + 1;
            System.out.print(password);
            String myString = Integer.toString(password);
            output.write(myString);
        }
 
        output.close();
        System.out.println("");
        System.out.println("Password written to file.");
 
    }
}

There are no errors in that code. It was tested before posting. Did you include the imports? import java.io.*;
