Java输入若干整数(不少于10个),用–1结束输入,以每行三个数的形式输出,再从这些数中选出所有奇数放在另一个数组中，然后输出.

直接放代码:

import java.util.ArrayList;
import java.util.Scanner;
public class _02 {
   
    public static void main(String[] args) {
   
        System.out.println("请输入几个数,以-1结束: ");
        Scanner sc = new Scanner(System.in);
        ArrayList<Integer> al1 = new ArrayList<>();//寄宿第一次输入的数字
        //ArrayList<String> al2=new ArrayList<>();//寄宿三行
        String s = "";
        int y = 0;
        ArrayList<Integer> al3 = new ArrayList<>();//寄宿奇数
        for (; true; ) {
   
            int e = sc.nextInt();
            al1.add(e);
            if (e % 2 != 0) {
   
                al3.add(e);
            }
            if (e == -1) {
   
                break;
            }
        }
        int model = al1.size() / 3;
        int l = 0;
        //System.out.println(model);
        int k = al1.size();
        System.out.println("每行三个输出:");
        for (int i = 0; i <= model; i++) {
   
            if (k > 3) s = al1.get(l) + "," + al1.get(l + 1) + "," + al1.get(l + 2);
            else if (k >= 2) s = al1.get(l) + "," + al1.get(l + 1);
            else if (k >= 1) s = al1.get(l) + " ";
            l = l + 3;
            System.out.println(" :" + s);
            k = k - 3;
        }
        System.out.println("****************");
        System.out.println("其中奇数有: ");
        System.out.println(" " + al3);

    }
}

输出如图:
