嵌套的循环艺术

Question

所以我知道有类似的问题，但没有一个看起来像这个“复杂”。 这是该计划的预期输出。

这是构建身体的for-loop

    divider();
    for (int fb=0;fb<=2;fb++) {
        System.out.print("|");
        System.out.print(fSlash+bSlash);
            for (int i=0;i<=fb*2;i++) {
                System.out.print(fSlash+bSlash);
            }
    }
    for (int fb=2;fb>=0;fb--) {
        System.out.print("|");
        System.out.print(bSlash+fSlash);
            for (int i=fb;i<=fb*3;i++) {
                System.out.print(bSlash+fSlash);
        }
    }

如你所见，我错过了下降期。

Answer 1

public static void topCenter(String fSlash, String bSlash) {
    divider();
    for(int fb = 0; fb <= 2; fb++) {
        System.out.print("|");
        for(int repeat = 0; repeat < 2; repeat++) {
            printDots(2 - fb);
            for(int i = 0; i <= fb; i++) {
                System.out.print(fSlash + bSlash);
            }
            printDots(2 - fb);
        }
        System.out.println("|");
    }
    for(int fb = 2; fb >= 0; fb--) {
        System.out.print("|");
        for(int repeat = 0; repeat < 2; repeat++) {
            printDots(2 - fb);
            for(int i = fb; i <= fb * 2; i++) {
                System.out.print(bSlash + fSlash);
            }
            printDots(2 - fb);
        }
        System.out.println("|");
    }
    //bottomCenter(fSlash, bSlash);
}

public static void printDots(final int count) {
    for(int i = 0; i < count; i++) {
        System.out.print(".");
    }
}

Answer 2

虽然这个问题已经得到解答; 当我在学校看到它并且今天到家后我开始自己的实施时，它相当痒痒。 以为我会在这里分享它，因为它可能对你有用。 如果您想知道，我将所有内容附加到StringBuilder ，以避免其他进程使用System.out打印流的潜在错误并破坏艺术。 因此，只需一次打印所有内容。
