Thread: Random variant.

Hello. I have a program:

package Dice;
 
import java.util.Scanner;
 
public class Dice {
 
int game;
 
String [] players;
 
int [] Wonthenumberofturns;
 
 
int esk;
 
int [] er;
 
int [] turnswinners;
 
private Scanner scan;
private Scanner scan2;
private Scanner scan3;
 
 
public void Players(){
scan = new Scanner(System.in);
System.out.println("Insert how many players play in game:");
int game = scan.nextInt();
scan.nextLine();
players = new String [game];
Wonthenumberofturns = new int [game];
for(int i = 0; i < game; i++){
System.out.println("Insert player number" + Integer.toString(i+1));
players[i] = scan.nextLine();
Wonthenumberofturns[i] = 0;
}
//scan.close();
}
 
public void Turnnumber(){
scan2 = new Scanner(System.in);
System.out.println("Enter the desired number of turns");
game = scan2.nextInt();
scan2.nextLine();
er = new int [game];
turnswinners = new int [game];
}
 
public void Go(int Gonumber){
int Biggest = 0;
int Record = 0;
scan3 = new Scanner(System.in);
for(int i = 0; i < game; i++){
System.out.println("Enter the number of players rolling the" + players[i]);
int Rezult = scan3.nextInt();
scan3.nextLine();
if (Rezult > Biggest){
Biggest = Rezult;
Record = i;
}
}
System.out.println("Turn win the player" + players[Record]);
turnswinners[Gonumber] = Record;
er[Gonumber] = Biggest;
Wonthenumberofturns[Record]++;
}
 
public void Winner(){
for(int i = 0; i < game; i++){
int winnernumber = turnswinners[i];
int taskai = er[i];
System.out.println("Turn" + Integer.toString(i+1) + "won" + players[winnernumber]);
System.out.println("collected" + Integer.toString(taskai) + "points");
}
int winners = 0;
int winner = 0;
for (int i = 0; i < game; i++) {
if (Wonthenumberofturns[i] > winners) {
winners =Wonthenumberofturns[i];
winner = i;
}
}
System.out.println("Game winner" + players[winner]);
}
public void zaid(){
Players();
Turnnumber();
for(int i = 0; i < game; i++){
Go(i);
}
Winner();
}
}

And how can I change turn number in random?
I have a code:

int number = (int)Math.round((Math.random() * 5 + 1));

Can you correct code? And show me?

This cut I can use in my program to make a random turn numbers?

Like this?:

public void random() {
Random dice = new Random();
int number;
 
for(int counter = 1; counter<=10;counter++){
number = dice.nextInt(6);
	return; 
}
}

I don't know.. I don't understand how to create it...

I have a main().

package Dice;
 
public class Main {
 
 
/**
 
*
@param args
 
*/
 
public static void main(String[] args) {
 
Dice game = new Dice ();
game.zaid();
 
}
 
}

When I start the program, she show me "Select a way to run 'Random' ":
Java Applet;
Java application;

And when I select one, then she show: "Selection does not contain a main type"...

Yes.

Look.

package Random;
 
public class Random {
 
	private static int i;
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		int min = 0;
		int max = 10;
 
		for(int i1 = 0; i1 < max; i1++){
		i1 = (int) (Math.random() * (max+min));
 
		System.out.println(i1);
	}
	}
 
	public static int getI() {
		return i;
	}
 
	public static void setI(int i) {
		Random.i = i;
	}
}

I tried it and I got different number.
Like:
1
2
5
0
0
7
1
6
7
3

Yes. Always is different numbers. I mean:
First time:
2
1
4
9
...
Second time:
6
8
4
9
...
But not more than 10. Can you tell me how to do to infinity?

public static void main(String[] args) {

		for(int i1 = 0; i1 < max; i1++){
		setI2((int) (Math.random() * (max+min)));
 
		System.out.println(i2);
	}
	}

Yes. I have a question... In my first post...
