采用多种算法，模拟摇奖：从1-36中随机抽出8个不重复的数字

package liu0913;

import java.util.Random;

public class Yaohao {

	public static void main(String[] args) 
	{	
		Random ran=new Random();
		int[] arr=new int[8];       

		for(int i=0;i<8;i++)
		{
			arr[i]=ran.nextInt(36);
			for(int j=0;j<i;j++)
			{
				if(arr[i]==arr[j])
				{
					i--;
				}
			}
		}
		System.out.println(arr[0]+" "+arr[1]+" "+arr[2]+" "+arr[3]+" "+arr[4]+" "+arr[5]+" "+arr[6]+" "+arr[7]);
