I'm trying to create a country quiz guessing game however, I have run into a problem. I want there to be a menu where a country is displayed and underneath there should be three capitals to choose from of which one is correct. The problem is I don't want the correct answer to be at the same position for every country, in other words I want the order of the alternatives to be randomized but, I'm not sure of how this could be done...
I have not come far with my code but here is my method:
public static void gissaStadAlt(LandStad[] list) {
for(int i = 0; i < list.length; i++) {
int rand = (int)(Math.random() * 10);
JOptionPane.showInputDialog(null, "Which of the alternatives is the capital in " + list[i].land + "?" + "\n" +
"1." + list[rand].stad + "\n" +
"2." + list[i].stad + "\n" +
"3." + list[rand].stad);
}
}
I want the position of list[i].stad to be randomized
This is my LandStad class:
public class LandStad {
String land;
String stad;
}
Why not just shuffle the array that you get? That way you can keep the JOptionPane dialogue the same, ie:
public static void gissaStadAlt(LandStad[] list)
{
Collections.shuffle(Arrays.asList(list));
JOptionPane.showInputDialog(null, "Which of the alternatives is the
capital in " + list.getLand() + "?" + "\n" +
"1." + list[0].city + "\n" +
"2." + list[1].city + "\n" +
"3." + list[2].city);
}
You can use something like:
public static void gissaStadAlt(LandStad[] list) {
for(int i = 0; i < list.length; i++) {
String[] options = new String[3];
int rand = i;
while(rand!=i){
rand = (int)(Math.random() * 10);
}
options[0] = list[rand].city;
int k = rand;
while(rand!=i && rand!=k){
rand = (int)(Math.random() * 10);
}
options[1] = list[rand].city;
options[2] = list[i].city;
int[] randomize = {123,132,213,231,312,321};
int num = randomize[(int)(Math.random() * 6)];
for(int i=0;i<3;i++){
int g = num/100;
options[i] = g + ". " + options[i];
num%=100;
num*=10;
}
Arrays.sort(options);
JOptionPane.showInputDialog(null, "Which of the alternatives is the capital in " + list[i].land + "?" + "\n" +
options[0] + "\n" +
options[1] + "\n" +
options[2]);
}
