java不知道如何打印这个？

Question

我应该修改为作业编写的代码：

public class ToweringStrings2 {

    public static final int H = 2; //constant for the tower

    public static void main(String[] args) {
        drawTowers(H);
    }

    public static void drawTowers(int H) {
        for (int i = 1; i <= H; i++) {
            System.out.print(" ");
            for (int j = 1; j <= i; j++) {
                System.out.print("+");
            }
            System.out.println();
        }
        for (int k = 1; k <= H + 2; k++) {
            System.out.print("@");
        }
        System.out.println();
    }
}

因此，它会打印从1开始的序列号，而不是+s。目前，它会打印：

这就是新代码应该打印的内容：

等等

由于某种原因，我真的被卡住了，无法理解

Answer 1

您可以创建一个额外的变量来打印和递增

就像这样：

public class ToweringStrings2 {
    public static final int H = 10; //constant for the tower

    public static void main(String[] args) {
        drawTowers(H);
    }

    public static void drawTowers(int H) {
        int count = 1;
        for (int i = 1; i <= H; i++) {
            System.out.print(" ");
            for (int j = 1; j <= i; j++) {
                System.out.print(count++ + " ");
            }
            System.out.println();
        }
        for (int k = 1; k <= H + 2; k++) {
            System.out.print("@ ");
        }
        System.out.println();
    }
}
