7-5 sdut-oop-1 简单的复数运算

### Python实现复数运算 以下是基于Python的复数运算实现代码，利用Python内置的`complex`类型来简化复数的操作[^1]： ```python def complex_operations(): results = [] x_real, x_imaginary = map(int, input().split()) x = complex(x_real, x_imaginary) while True: line = input() if line.strip() == "0 0 0": break y_real, y_imaginary, op = line.split() y = complex(int(y_real), int(y_imaginary)) if int(op) == 1: # 加法 result = x + y elif int(op) == 2: # 减法 result = x - y elif int(op) == 3: # 乘法 result = x * y else: continue results.append(result) for res in results: print(f"{int(res.real)} {int(res.imag)}" .replace("j", "").replace("+", "")) if __name__ == "__main__": complex_operations() ``` 上述代码实现了读取输入并执行复数加减乘操作的功能。通过循环不断接收输入直到遇到终止条件 `0 0 0`。 --- ### Java实现复数运算 对于Java中的复数运算，则需要手动定义一个`Complex`类来进行封装[^2]。下面是一个完整的示例代码： ```java class Complex { private double real; private double imaginary; public Complex(double real, double imaginary) { this.real = real; this.imaginary = imaginary; } public Complex add(Complex other) { return new Complex(this.real + other.real, this.imaginary + other.imaginary); } public Complex subtract(Complex other) { return new Complex(this.real - other.real, this.imaginary - other.imaginary); } public Complex multiply(Complex other) { double r = this.real * other.real - this.imaginary * other.imaginary; double i = this.real * other.imaginary + this.imaginary * other.real; return new Complex(r, i); } @Override public String toString() { return (real != 0 ? real + " " : "") + (imaginary >= 0 && real != 0 ? "+" : "") + (imaginary != 0 ? Math.abs(imaginary) + "i" : ""); } } public class Main { public static void main(String[] args) { java.util.Scanner scanner = new Scanner(System.in); // 初始化 X System.out.println("Enter the first complex number:"); double xr = scanner.nextDouble(); double xi = scanner.nextDouble(); Complex x = new Complex(xr, xi); List<Complex> results = new ArrayList<>(); while (true) { System.out.println("Enter Y and operation code or '0 0 0' to stop:"); double yr = scanner.nextDouble(); double yi = scanner.nextDouble(); int opCode = scanner.nextInt(); if (yr == 0 && yi == 0 && opCode == 0) { break; } Complex y = new Complex(yr, yi); switch (opCode) { case 1 -> results.add(x.add(y)); case 2 -> results.add(x.subtract(y)); case 3 -> results.add(x.multiply(y)); default -> {} } } for (Complex c : results) { System.out.println(c.toString()); } } } ``` 此代码创建了一个名为`Complex`的类用于处理复数的相关计算，并提供了加法、减法以及乘法的方法。 --- ####
