JAVA从数组中取随机数

import java.util.Random;

public class SuiJiShu {
public static void main(String[] args) {
Random random=new Random();
int [] hong={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33};
int [] lan={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16};
for(int i=0;i<6;i++){
System.out.print(hong[random.nextInt(33)]+",");
}
System.out.println();
for (int i = 0; i < 1; i++) {
System.out.print(lan[random.nextInt(16)]+",");
}
}

}
