Question

(java) Using your PairOfDice class write an application that simulates 100 pass-line bets and output the results of each bet to an output file. Also, keep a running total of how many wins and losses. Output those totals at the end of your run. (not sure on how to implement file IO to output a separate text file, that will display how many wins and losses as well as the outputs from each roll)

pairofdice.java

import java.util.Random;

public class PairOfDice {
  
    private int die1;
    private int die2;

  
    public PairOfDice()
    {

    }
  
    public void roll()
    {
        Random d1 = new Random();
        Random d2 = new Random();
        die1 = d1.nextInt(6) + 1;
        die2 = d2.nextInt(6) + 1;
    }
  
    public int getDie1()
    {
        return die1;
    }
  
    public int getDie2()
    {
        return die2;
    }
  
    public int getTotalValue()
    {
        return die1 + die2;
    }
  
    @Override
    public String toString()
    {
        return die1 + "+" + die2 + " =" + getTotalValue();
    }

Explanation / Answer

You can use file io library to write output to a separate file.

This library has functions like write to file and read from file.

2. FileInputStream in = null; // declare in file input stream variable to take input from file.

  in = new FileInputStream("filename"); // like this you can open any file you want

FileOutputStream out = null; // It is a declaration for output stream

After closing file, just check current folder your output file is ready.
