复数类的除法加上自定义异常处理 java

在Java中,我们可以创建一个复数类(ComplexNumber),然后为其提供除法运算,并利用自定义异常处理机制来处理可能出现的非零除数情况。以下是基本步骤:
首先,定义一个复数类`ComplexNumber`,包含实部(real part)和虚部(imaginary part)的属性,以及表示加减乘除操作的方法:
```java
public class ComplexNumber {
private double real;
private double imaginary;
public ComplexNumber(double real, double imaginary) {
this.real = real;
this.imaginary = imaginary;
}
// Getters and setters for real and imaginary parts
public ComplexNumber divide(ComplexNumber divisor) throws NonZeroDivisorException {
if (divisor.getReal() == 0 && divisor.getImaginary() == 0) {
throw new NonZeroDivisorException("Cannot divide by zero");
}
double denominator = Math.pow(divisor.getReal(), 2) + Math.pow(divisor.getImaginary(), 2);
return new ComplexNumber(
(this.getReal() * divisor.getReal() - this.getImaginary() * divisor.getImaginary()) / denominator,
(this.getImaginary() * divisor.getReal() + this.getReal() * divisor.getImaginary()) / denominator
);
}
}
class NonZeroDivisorException extends Exception {
public NonZeroDivisorException(String message) {
super(message);
}
}
```
在这个例子中,当试图用0除以另一个复数时,会抛出`NonZeroDivisorException`。这是对`divide`方法的一种异常处理。
