我创建了一个彩票程序,在0-9之间随机生成3个数字,然后随机生成3个中奖数字。我需要有关如何使程序显示中奖者(如果有)和显示中奖人数的帮助。
所以像:
获奖者:
人1
人5
获奖人数:2
这是我的程序
import java.util.Random;
public class TwoDArray
{
public static void main(String[] args)
{
int[][] table = new int[50][3];
int[][] win = new int[1][3];
Random rand = new Random();
int i = 1;
// Load the table with values
for (int row=0; row < table.length; row++)
for (int col=0; col < table[row].length; col++)
table[row][col] = rand.nextInt(7-0 +1)+0 + col;
// Load the winning Values
for (int row=0; row < win.length; row++)
for(int col=0; col < win[row].length; col++)
win[row][col] = rand.nextInt(7-0 +1)+0 + col;
// Print the table of People
for (int row=0; row < table.length; row++)
{
System.out.print("Person" + i++ +":\t");
for (int col=0; col < table[row].length; col++)
System.out.print(table[row][col] + "\t");
System.out.println();
}
//Print the Winning Numbers
for (int row=0; row < win.length; row++)
{
System.out.print("\nThe winning numbers are:\t");
for(int col=0; col < win[row].length; col++)
System.out.print(win[row][col] + "\t");
System.out.println();
}
}
}
最佳答案
您想要另一个for循环。就像是:
int counter = 0;
for (int i =0; i < table.length; i++){
if (table[i][0] == win[0][0] && table[i][1] == win[0][1] && table[i][2] == win[0][2])
{
counter++;
System.out.println("Person " + i);
}
}
System.out.println("There were " + counter + " winners.");
