java输出一个会动的空心菱形

以下是使用Java语言输出一个会动的空心菱形的示例代码：

public class MovingDiamond {
    public static void main(String[] args) {
        int size = 10;
        int mid = size / 2;
        for (int i = 0; i < size; i++) {
            for (int j = 0; j < size; j++) {
                if (Math.abs(j - mid) + Math.abs(i - mid) == mid) {
                    System.out.print("*");
                } else {
                    System.out.print(" ");
                }
            }
            System.out.println();
        }
        int x = mid, y = mid;
        while (true) {
            for (int i = 0; i < mid; i++) {
                System.out.print("\r");
                for (int j = 0; j < size; j++) {
                    if (Math.abs(j - x) + Math.abs(i - y) == mid) {
                        System.out.print("*");
                    } else {
                        System.out.print(" ");
                    }
                }
                try {
                    Thread.sleep(50);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            for (int i = mid; i < size; i++) {
                System.out.print("\r");
                for (int j = 0; j < size; j++) {
                    if (Math.abs(j - x) + Math.abs(i - y) == mid) {
                        System.out.print("*");
                    } else {
                        System.out.print(" ");
                    }
                }
                try {
                    Thread.sleep(50);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            x = size - x - 1;
            y = size - y - 1;
        }
    }
}

这段代码首先在控制台中输出一个静态的空心菱形，然后通过while循环使其动起来。循环中通过不断改变菱形的位置，再将其在控制台中输出即可实现菱形的移动效果。
