Opinon Poll Assignment
Can someone please help!. I am doing an assginment in college. I am required to do a world cup opinion poll where fans can vote which team will win the world cup in 2006. There 4 radio buttons represanting 4 countries, Brazil, England, Germany and Italy.A fan selects a button and clicks the Vote button to vote. A the vote button must be kept disabled until a button is selected. Each vote cast should increase the bar chart for that partcular team. I am doing something terribly wrong somewhere in my code. I think it is in the ActionPerformed method. I am not good in java so your help is important. I hope my explantion is sensible. Here is my code below.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.geom.*;
public class TaskA extends JFrame implements ActionListener{
JLabel question = new JLabel(" Who will win the World Cup?");//Question Label
double x, y, height, width;
int country [] = new int [4];
String teams [] = {"Brazil", "England", "Germany", "Italy"};
Font italicFont = new Font("Arial",Font.ITALIC,12);
JButton btnVote ;
public TaskA(){// Constructor
super("Assign06b");
setSize(550, 450);// size of thye frame
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Font currentFont = new Font("Arial", Font.BOLD,20);//creating a font object for the banner/question
question.setFont(currentFont);
Font westFont = new Font("Arial", Font.ITALIC,12);// creating a font object for bar names
JRadioButton brazil = new JRadioButton("Brazil");// RadioButton1
brazil.setActionCommand("Brazil");
JRadioButton england = new JRadioButton("England");// RadioButton2
england.setActionCommand("England");
JRadioButton germany = new JRadioButton("Germany");// RadioButton3
germany.setActionCommand("Germany");
JRadioButton italy = new JRadioButton("Italy");// RadioButton4
italy.setActionCommand("Italy");btnVote.setEnabled(true);// how can I make this to appear false then change to true when radio button is selected?
btnVote.addActionListener(this);
ButtonGroup group = new ButtonGroup();//Group to hold buttons
group.add(brazil);
group.add(england);
group.add(germany);

country[1] = 0;
country[2] = 0;
country[3] = 0;
}
public void actionPerformed (ActionEvent event){
Object source = event.getSource();
// teams = "Brazil", "England", "Germany", "Italy";

System.out.println(country[0] + "votes" + country[0] + "%");
