随机排座位,首先的知道有多少个座位吧?以下是60个座位的随机排序!
import java.util.Random;
public class select{ //建一个类命名为selcet.java
public static void main(String[] args)
{
System.out.println("随机的九个数是:");
int a[] = new int[60]; //总的有60个座位!
Random random = new Random();
for (int i=0;ia.length;i++)
{
int z = random.nextInt(60); //随机抽取60个座位
a[i] = Math.round(z);
if (i = 1)
{
int j = i;
while (j = 0)
{
if (a[i] == a[j])
{
int k = random.nextInt(60);//随机抽取60个座位
a[i] = Math.round(k);
}
j--;
}
}
System.out.print(a[i] + 1 + " ");
}
}
