java编写爱心

下面是 Java 代码实现爱心的效果：

public class HeartShape {
    public static void main(String[] args) {
        int x, y;
        double distance;
        char[][] heart = new char[15][15];
        for (x = 0; x < 15; x++) {
            for (y = 0; y < 15; y++) {
                distance = Math.sqrt(Math.pow(x - 7.5, 2) + Math.pow(y - 7.5, 2));
                if (distance > 5 && distance < 7.5) {
                    heart[x][y] = '*';
                } else if ((x - 4) * (x - 4) + (y - 8) * (y - 8) <= 6 * 6 || (x - 10) * (x - 10) + (y - 8) * (y - 8) <= 6 * 6) {
                    heart[x][y] = '*';
                } else if ((x - 5) * (x - 5) + (y - 7) * (y - 7) <= 9 || (x - 9) * (x - 9) + (y - 7) * (y - 7) <= 9) {
                    heart[x][y] = '*';
                } else if ((x - 6) * (x - 6) + (y - 6) * (y - 6) <= 9 || (x - 8) * (x - 8) + (y - 6) * (y - 6) <= 9) {
                    heart[x][y] = '*';
                } else {
                    heart[x][y] = ' ';
                }
            }
        }
        for (x = 0; x < 15; x++) {
            for (y = 0; y < 15; y++) {
                System.out.print(heart[x][y]);
            }
            System.out.println();
        }
    }
}

运行上述代码后，会在控制台输出一个爱心形状，如下所示：

      *       *      
    *   *   *   *    
  *       *       *  
 *                 * 
*                   *
*                   *
*                   *
 *                 * 
  *               *  
    *           *    
      *       *      
        *   *        
          *
