Java ArrayList exercise-store random

*

Title:
 * Generate 6 random integers between 1 and 33, add to the set, and traverse the set
 * 
 * 
 * Idea:
 * 1. Need to be purely 6 numbers, create a set, <Integer> use numbers
 * 2. To generate random numbers, you need to use Random
 * 3. It takes 6 times to generate 6 random numbers, for loop
 * 4. Call r.nextInt (int n) in the loop, the parameter is 33,0 ~ 32; overall +1 Only 33
 * 5. Add the number to the collection: add
 * 6 traverse the collection: for, size, get

import java.util.ArrayList;
import java,util.Random;
public class Text01ArrayListRandom {

	public static void main(String[] args) {
		ArrayList<Integer> list=new ArrayList<>();
		Random r=new Random();
		for(int i=0;i<6;i++) {//利用for遍历  随机得到6个数， 然后再下面循环遍历出来
			int num=r.nextInt(33)+1;
		list.add(num);
		}
		for(int i=0;i<list.size();i++) {//遍历出集合
			System.out.println(list.get(i));
		}
	}

}
