I have decided to learn Java with </dream.in.code> as my only learning resource

So far I have managed to choose an IDE and create my first Java program.

I decided to start small and get used to the language with some simple programs. I have started with a random number guessing game and it's up to DIC to teach me how to get and display user input and also how to create random numbers.

I thought that the Java Tutorials section would be the best place to start. There are tons of tutorials in there and I found one that fit the bill Basic Java for N00blets Pt.2: Important Classes. This tutorial introduced me to the Scanner class which I would be using to get user input and also the Random class for creating random numbers, integral to this game.

I am already a C++ programmer and this probably shows in my code but here is my first Java game

Game.java

package javagameapp;

import java.util.Scanner;
import java.util.Random;

/**

public class Game 
{
    Game()
    {
        m_userInput = new Scanner(System.in);
        m_randNum = new Random();
    }
    
    public void Start()
    {
        m_theNumber = m_randNum.nextInt(100);
        
        System.out.println("Welcome to the random number game!\n"
                + "Please make your first guess of a number between 0-100\n");
        
         m_theGuess = m_userInput.nextInt();  
         
         m_bIsRunning = true;
    }
    
    public boolean IsRunning()
    {
        return m_bIsRunning;
    }
    
    public void Run()
    {
        if(m_theGuess != m_theNumber)
        {
            if(m_theGuess < m_theNumber)
            {
                System.out.println("Too low, try again!\n");
                m_theGuess = m_userInput.nextInt();
            }
            else if(m_theGuess > m_theNumber)
            {
                System.out.println("Too high, try again!\n");
                m_theGuess = m_userInput.nextInt();
            }
        }
        else
        {
            System.out.println("You got it!\n");
            Start();
        }
    }
    
    private Scanner m_userInput;
    private Random  m_randNum;
    
    private int m_theNumber;
    private int m_theGuess;
    
    private boolean m_bIsRunning;
}

JavaGameApp.java

package javagameapp;

/**
 *
 * @author stayscrisp
 * 
 */

public class JavaGameApp {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) 
    {
        // create the game and related objects
        Game theGame = new Game();
        
        // start the game
        theGame.Start();
        
        // run until the number is guessed - call Start() if guessed
        while(theGame.IsRunning())
        {
           theGame.Run();
        }
    }
}

I think next I will attempt something a little more difficult that uses more OOP concepts. So far I have not had to use any resource outside of DIC
