复数四则运算法则 假设 z1 = a + bi，z2 = c + di 和：z1 + z2 = (a+c) + (b+d)i 差：z1 - z2 = (a-c) + (b-d)i 积：z1 * z2 = (ac-bd) + (bc + ad)i 商：z1 / z2 = (ac + bd)/(c * c+d * d) + (bc-ad)/(c * c+d * d)i 编程要求 根据提示，在右侧编辑器补充代码，计算并输出两个复数的和、差、积、商运算结果。用java写

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入第一个复数的实部和虚部：");
        double a = scanner.nextDouble();
        double b = scanner.nextDouble();
        System.out.println("请输入第二个复数的实部和虚部：");
        double c = scanner.nextDouble();
        double d = scanner.nextDouble();

        // 计算和
        double sumReal = a + c;
        double sumImag = b + d;
        System.out.println("和：" + sumReal + " + " + sumImag + "i");

        // 计算差
        double diffReal = a - c;
        double diffImag = b - d;
        System.out.println("差：" + diffReal + " + " + diffImag + "i");

        // 计算积
        double productReal = a * c - b * d;
        double productImag = b * c + a * d;
        System.out.println("积：" + productReal + " + " + productImag + "i");

        // 计算商
        double denominator = c * c + d * d;
        double quotientReal = (a * c + b * d) / denominator;
        double quotientImag = (b * c - a * d) / denominator;
        System.out.println("商：" + quotientReal + " + " + quotientImag + "i");
    }
}
