java实现复数加减乘除取模

好的，以下是 Java 实现复数加减乘除取模的代码示例：

public class Complex {
    private double real;
    private double imag;

    public Complex(double real, double imag) {
        this.real = real;
        this.imag = imag;
    }

    public Complex add(Complex other) {
        return new Complex(this.real + other.real, this.imag + other.imag);
    }

    public Complex subtract(Complex other) {
        return new Complex(this.real - other.real, this.imag - other.imag);
    }

    public Complex multiply(Complex other) {
        double real = this.real * other.real - this.imag * other.imag;
        double imag = this.real * other.imag + this.imag * other.real;
        return new Complex(real, imag);
    }

    public Complex divide(Complex other) {
        double denominator = other.real * other.real + other.imag * other.imag;
        double real = (this.real * other.real + this.imag * other.imag) / denominator;
        double imag = (this.imag * other.real - this.real * other.imag) / denominator;
        return new Complex(real, imag);
    }

    public double modulus() {
        return Math.sqrt(this.real * this.real + this.imag * this.imag);
    }
}
