写一个Java爱心程序

下面是一个简单的 Java 程序，用于在控制台上输出爱心字符图形：

public class Heart {
    public static void main(String[] args) {
        System.out.println("\u2665\u2665\u2665\u2665\u2665");
        System.out.println("\u2665\u0020\u0020\u0020\u2665");
        System.out.println("\u2665\u0020\u2665\u0020\u2665");
        System.out.println("\u2665\u0020\u0020\u0020\u2665");
        System.out.println("\u2665\u2665\u2665\u2665\u2665");
    }
}

运行该程序后，您将在控制台上看到爱心形的字符图形。

利用JAVA 写一个爱心程序

以下是一个简单的JAVA程序，可以输出一个爱心形状：

public class Love {
    public static void main(String[] args) {
        for (double y = 1.5; y > -1.5; y -= 0.1) {
            for (double x = -1.5; x < 1.5; x += 0.05) {
                double a = x * x + y * y - 1;
                System.out.print(a * a * a - x * x * y * y * y <= 0.0 ? "♥" : " ");
            }
            System.out.println();
        }
    }
}

运行程序，就会输出一个爱心形状：

      ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥  
   ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥  
 ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥  
♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥

   ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥  
      ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥  

用Java写一个爱心程序

好的，以下是用Java写一个爱心程序的示例代码：

public class LoveHeart {

    public static void main(String[] args) {
        int x, y, size = 20;
        double d;
        for (y = size; y >= -size; y--) {
            for (x = -size; x <= size; x++) {
                d = Math.pow(Math.pow(x * 0.04, 2) + Math.pow(y * 0.1, 2) - 1, 3) - Math.pow(x * 0.04, 2) * Math.pow(y * 0.1, 3);
                System.out.print(d <= 0.0 ? '*' : ' ');
            }
            System.out.println();
        }
    }
}

这段程序通过嵌套的for循环和数学计算实现了一个爱心的图案。在控制台中运行该程序即可看到输出的爱心图案。
