好的,下面是一个完整的示例,演示如何使用单个JSP文件实现复数加减乘除四则运算。
```jsp
<%@ page language="java" %>
<%
// 根据表单中的操作符选择不同的操作
String operator = request.getParameter("operator");
double real1 = Double.parseDouble(request.getParameter("real1"));
double imag1 = Double.parseDouble(request.getParameter("imag1"));
double real2 = Double.parseDouble(request.getParameter("real2"));
double imag2 = Double.parseDouble(request.getParameter("imag2"));
double resultReal = 0;
double resultImag = 0;
switch (operator) {
case "+":
resultReal = real1 + real2;
resultImag = imag1 + imag2;
break;
case "-":
resultReal = real1 - real2;
resultImag = imag1 - imag2;
break;
case "*":
resultReal = real1 * real2 - imag1 * imag2;
resultImag = real1 * imag2 + imag1 * real2;
break;
case "/":
double denominator = real2 * real2 + imag2 * imag2;
resultReal = (real1 * real2 + imag1 * imag2) / denominator;
resultImag = (imag1 * real2 - real1 * imag2) / denominator;
break;
}
request.setAttribute("resultReal", resultReal);
request.setAttribute("resultImag", resultImag);
%>
<!DOCTYPE html>
<html>
<head>
<title>Complex Number Calculator</title>
</head>
<body>
<h1>Complex Number Calculator</h1>
<form method="post">
<label for="real1">Real Part 1:</label>
<input type="text" name="real1" id="real1" required />
<label for="imag1">Imaginary Part 1:</label>
<input type="text" name="imag1" id="imag1" required />
<br />
<label for="real2">Real Part 2:</label>
<input type="text" name="real2" id="real2" required />
<label for="imag2">Imaginary Part 2:</label>
<input type="text" name="imag2" id="imag2" required />
<br />
<label for="operator">Operator:</label>
<select name="operator" id="operator">
<option value="+">+</option>
<option value="-">-</option>
<option value="*">*</option>
<option value="/">/</option>
</select>
<br />
<input type="submit" value="Calculate" />
</form>
<%
if (resultReal != 0 || resultImag != 0) {
%>
<h2>Result:</h2>
<p><%= resultReal %> + <%= resultImag %>i</p>
<%
}
%>
</body>
</html>
```
在这个文件中,我们首先根据表单中的操作符选择不同的操作,然后从HTTP请求参数中获取两个复数的实部和虚部。接下来,我们执行相应的复数运算,并将结果存储在请求属性中。最后,我们在HTML页面中显示表单以获取用户输入,并在需要时显示计算结果。
请注意,在乘法和除法运算中,我们使用了标准的复数运算公式,以计算两个复数的乘积和商。
