import java.util.Random;

public class Main {
    static final Random random = new Random();
    static final char[] dots = new char[]{'*', '#', '.', '-', '\n'};//马里奥场景中包含的字符
    static final int rowLimit = 62;//场景中一行最多有62个字符

    public static void main(String[] args) {
        //随机输出字符
        final int colLen = 22;//场景有22行
        for (int count = 0; count < colLen; count++) {
            randomInputRow();
        }
    }

    //随机输出一行字符，换行或到上限结束
    static void randomInputRow() {
        for (int count = 0; count < rowLimit; count++) {
            char rand = dots[random.nextInt(dots.length)];
            System.out.print(rand);
            if (rand == '\n') break;
        }
    }
}

这是最方便的解法吗
