Thread: Football Betting System

Hi there I am doing an assignment on Java Programming and need any help on this case study:

You have been asked to develop a Football Betting System (FBS). The FBS should work as follows:
You have to create a database containing gaming data (20 team names and team Rating). The program should:
a. Randomly extract the team names and team rating and put two of each against other;
b. According to the difference in the rating, the program should show the user the probability of the result (1,X,2) and how much money he would win for each game,
c. Allow the user to bet on the games by choosing either 1,X, or 2 near each game;
d. Show the results of the actual random scores and the output them next to the user’s predictions;
e. Finally calculate the total prize the user won according to the number of bets he won
Hint - Keep in mind that every difference point in the rating is equal to 1.50 Euro difference in betting. The last amount of money that can be won from a bet is 1.20c

Any help will be greatly appreciated

Thanks

Next step will be for you to design the program you need and write some code.
Come back here when you have problems.

here is some code on 20 football teams that need to be randomly met with a 1,2, X rating and the score you think im doing ok as i am very new to java

thanks

public static void main(String args[])
Teams teams[]=new team[20];
teams[0]=(Arsenal,8);
teams[1]=(AstonVilla,7);
teams[2]=(Blackburn,6);
teams[3]=(Bolton,6);
teams[4]=(Chelsea,8);
teams[5]=(Everton,7);
teams[6]=(Fulham,6);
teams[7]=(Liverpool,8);
teams[8]=(ManchesterCity,8);
teams[9]=(ManchesterUnited,9);
teams[10]=(Newcastle,7);
teams[11]=(Norwich,4);
teams[12]=(QPR,4);
teams[13]=(Stoke,6);
teams[14]=(Sunderland,6);
teams[15]=(Swansea,4);
teams[16]=(Tottenham,7);
teams[17]=(WBA,5);
teams[18]=(Wigan,5);
teams[19]=(Wolves,5);

public string probability(team a,team b){
if(a.getrating==b.getrating)
return "x";
if(a.getrating>b.getrating)
return"1";
else
return"2"
}

team t1;
team t2;
int t1goals=-1
int t2goals=-1

java.util.Random

private void generate random score(){
Random r=new random();
t1goals=r.next int(7);
t2goals=r.next int(7);
}

Regarding the code you typed in:
You'd need a definition for the Teams class.
The syntax is not valid. You create Team objects with: new Team("name", rating)

Do you have any ideas of what the program should do to implement the steps you listed in post #1?

Hi norm i added some more code not sure what i am doing wrong and thanks for your help

package betting;


public class Team {

private String name; //name of team
private int rating = 0;

//constructor of class Team
public Team(String name, int rating) {
super();
this.name = name;
this.rating = rating;
}

//returns the name of the team
public String getName() {
return name;
}

//sets the name of the team
public void setName(String name) {
this.name = name;
}

//returns the rating of the team
public int getRating() {
return rating;
}

// sets the rating of the team to the new parameter
public void setRating(int rating) {
this.rating = rating;
}

//toString method to return whenever a team is called
public String toString() {
return "Team " + name + ", rating = " + rating;
}
}



public static void main(String args[])
Teams teams[]=new team[20];
teams[0]=(Arsenal,8);
teams[1]=(AstonVilla,7);
teams[2]=(Blackburn,6);
teams[3]=(Bolton,6);
teams[4]=(Chelsea,8);
teams[5]=(Everton,7);
teams[6]=(Fulham,6);
teams[7]=(Liverpool,8);
teams[8]=(ManchesterCity,8);
teams[9]=(ManchesterUnited,9);
teams[10]=(Newcastle,7);
teams[11]=(Norwich,4);
teams[12]=(QPR,4);
teams[13]=(Stoke,6);
teams[14]=(Sunderland,6);
teams[15]=(Swansea,4);
teams[16]=(Tottenham,7);
teams[17]=(WBA,5);
teams[18]=(Wigan,5);
teams[19]=(Wolves,5);

public string probability(team a,team b){
if(a.getrating==b.getrating)
return "x";
if(a.getrating>b.getrating)
return"1";
else
return"2"
}

team t1;
team t2;
int t1goals=-1
int t2goals=-1

java.util.Random

private void generate random score(){
Random r=new random();
t1goals=r.next int(7);
t2goals=r.next int(7);
}

public BetResult getResult() {
generateRandomScore();//generate actual score
//returning 1,2 or X according to actual result
String res;
if (t1Goals == t2Goals) {
res = "X";
} else if (t1Goals > t2Goals) {
res = "1";
} else {
res = "2";
}
return new BetResult(res, t1Goals, t2Goals);
}

Did you read my comments in post#4 about the syntax for creating Team objects?
