Blackjack – Java Programming
So after I went through a few more tutorials, I decided to create another app. I've integrated it to my original app, so in the welcome screen, it will ask if I want to use the Calculator or play Blackjack.
My first attempt at building a Blackjack game via Java programming. It works and is quite simple at the moment. The more I update it, the more complex it will get!
Here is the source code for the game. It's very simple and probably very messy! But hey... I'm still learning
package Blackjacks;
import java.util.Random;
import java.util.Scanner;
public class Blackjack {
public static void main(String[] args) {
//Scanner//
Scanner scan = new Scanner(System.in);
//Game Background Object//
BJBackground b = new BJBackground();
//Game Randomizer Object//
Random r = new Random();
//Dealing Cards and Generating Computers Cards//
System.out.println("Welcome to Blackjack.");
System.out.println("Would you like to play Blackjack? Yes or No");
String input = scan.next();
if (input.equalsIgnoreCase("yes")) {
b.play(true);
}
else return; // Assuming they type 'no' or something else, we can just quit the program here.
//Create Random Card Total for Computer//
int computer = 14 + r.nextInt(9);
//Stores Card Total for Computer//
b.setcomputer(computer);
//Creates Random Number for First Card//
int fcard = 1 + r.nextInt(11);
//Stores Card Number on First Card int//
b.setfcard(fcard);
//Creates Random Number for Second Card//
int scard = 1 + r.nextInt(10);
//Stores Card Number for Second Card int//
b.setscard(scard);
//Updates and Stores Player Score//
int player = scard + fcard;
b.setplayer(player);
System.out.println("Your first card was " + b.getfcard() + " and your second card was " + b.getscard());
//While Loop//
while (b.play()) {
System.out.println("Your total is " + b.getplayer());
if (b.getplayer() == 21) {
System.out.println("You have 21! You hit Blackjack!");
}
else System.out.println("Would you like another card? Hit or Stand");
input = scan.next();
while (input.equalsIgnoreCase("Hit")) {
//Creates Random Number for New Card//
int ncard = 1 + r.nextInt(10);
b.setncard(ncard);
b.setplayer(ncard);
System.out.println("Your new card is " + b.getncard());
System.out.println("Your new total is " + b.getplayer());
b.resetncard();
if (b.getplayer() <= 21); {
System.out.println("Would you like another card? Hit or Stand");
input = scan.next();
}
}
if (input.equalsIgnoreCase("Stand")) {
if ( b.getplayer() > 21 ) {
System.out.println("You had " + b.getplayer() + " and the computer had " + b.getcomputer() + ". The computer beat you..");
return;
}
if ( b.getplayer() > b.getcomputer() ) {
System.out.println("You had " + b.getplayer() + " and the computer had " + b.getcomputer() + ". You win!");
return;
}
if ( b.getplayer() < b.getcomputer() ) {
System.out.println("You had " + b.getplayer() + " and the computer had " + b.getcomputer() + ". You lose!");
return;
}
if ( b.getplayer() == b.getcomputer() ) {
System.out.println("You had " + b.getplayer() + " and the computer had " + b.getcomputer() + ". You drew!");
return;
}
}
}
}
}
package Blackjacks;
public class BJBackground {
//First Card//
private int fcard = 0;
//Second Card//
private int scard = 0;
//
private int ncard = 0;
//Player Card Total//
private int player = (fcard + scard + ncard);
//Computer Cards//
private int computer = 0;
//Boolean to Play//
private boolean play = true;
public void play(boolean play) {
this.play = play;
}
public boolean play() {
return play;
}
//Boolean for New card//
private boolean newcard = true;
public boolean newcard() {
return newcard;
}
//Sets First Card's new amount//
public void setfcard(int amount) {
this.fcard += amount;
}
//Allows Blackjack Class to know what the First Cards number is when called//
public int getfcard() {
return fcard;
}
//Sets Second Card's new amount//
public void setscard(int amount) {
this.scard += amount;
}
//Allows Blackjack Class to know what the Second Cards number is when called//
public int getscard() {
return scard;
}
//Sets new Card's amount//
public void setncard(int amount) {
this.ncard +=amount;
}
public int getncard() {
return ncard;
}
public void resetncard() {
ncard = 0;
}
public void setplayer(int amount) {
this.player += amount;
}
public int getplayer() {
return player;
}
//Sets Computer Score//
public void setcomputer(int amount) {
this.computer += amount;
}
//Allows Blackjack Class to know what the Computer score is//
public int getcomputer() {
return computer;
}
}
If anyone has any tips on how I can improve this, please do let me know!
I'm trying to figure out a way to allow you to take more than just one card at the start... Hopefully I'll figure it out soon!
My First Java App – Java Programming
Yeah so like, I know this isn't really a big deal to most people but I'm starting college in a couple of weeks and wanted to get a head start. So I decided to get a few online tutorials on Java programming and found something perfect.
It's a set of video tutorials done by a guy named Bucky Roberts on YouTube. The video tutorials are really easy to follow and give you a basic idea of how Java programming works - especially for us newbies. You should check him out! Here is a link to his YouTube channel:
http://www.youtube.com/user/thenewboston
Anyway, after an hour or so of watching his videos and following along, I have managed to somewhat make the backbone of a calculator and blackjack game. No interface or nothing yet, but that'll come later as I continue watching his videos.
Here is the source code for any of you who care:
import java.util.Scanner;
public class Welcome {
public static void main(String args[]){
//User Introduction//
Scanner input = new Scanner(System.in);
Calculator calcObject = new Calculator();
System.out.println("Hi, what is your name?");
String name = input.nextLine();
Scanner input2 = new Scanner(System.in);
System.out.println("Hi, " + name + ". Would you like to use our calulator? <Y/N>");
String answer = input2.nextLine();
if (answer.equals("Y"))
calcObject.calculator(name);
else if (answer.equals("y"))
calcObject.calculator(name);
else if (answer.equals("N"))
System.out.println("Aww! Okay " + name + ". Goodbye...
");
else if (answer.equals("n"))
System.out.println("Aww! Okay " + name + ". Goodbye...
");
}
}
import java.util.*;
public class Calculator {
public void calculator(String name) {
char again = 'Y';
while(again == 'Y' || again == 'y')
{
Scanner calc = new Scanner(System.in);
double fnum, snum, answer = 0;
String calcu;
System.out.println("Enter first number(s) for calculation: ");
fnum = calc.nextDouble();
System.out.println("What would you like to do? Use one of the following: +,-,* or /");
Scanner mdsa = new Scanner(System.in);
calcu = mdsa.next();
System.out.println("Enter second number for calculation: ");
snum = calc.nextDouble();
{
if (calcu.equals("+")) answer = fnum + snum;
else if (calcu.equals("-")) answer = fnum - snum;
else if (calcu.equals("*")) answer = fnum * snum;
else if (calcu.equals("/")) answer = fnum / snum;
}
System.out.println(name + ", the answer to your calculation is: " + answer);
Scanner response = new Scanner(System.in);
System.out.print("Would you like to do another calculation? <Y/N>");
again = response.nextLine().charAt(0);
}
}
}
Yes it is very basic, but then again I've only just started learning Java programming over the last couple of hours, so don't sue me.
As I continue watching his videos, I'll update this post with any additions I make to the source code. Hopefully I'll be able to make a nice looking calculator by the end of it... or at least until I give up! Hehe.
Well yeah. I'm having a lot of fun with this!
Check back later...

FIX: Microsoft Office – Spellcheck in French only!
A couple of days ago I had an issue regarding the Spellcheck not working in MS Word 2007. However this time I've come across another common issue where in Outlook or Outlook Express, Spellcheck is always in French. I've been getting quite a few issues where when a customer tries to use Outlook 2003/2007 or Outlook Express, their default spellcheck language is set to French and they're unable to change it.
After doing a lot of research over the internet I've found quite a bit of articles relating to this issue so I thought I'd write an article about it. Basically it is a common issue and has an easy fix to it...
