c# - 创建与 C# 异常类似的 Java 异常

Question

我需要在 Java 中创建一个异常，其操作方式与以下 C# 异常相同。

public class ResponseException : Exception
{
    internal ResponseException(int statusCode, String StatusCodeDescription, String request, String response)
        : base("Returned an error status code " + statusCode.ToString() + " (" + StatusCodeDescription + ") " + response)
    {
        this.StatusCode = statusCode;
        this.StatusCodeDescription = StatusCodeDescription;
        this.Request = request;
        this.Response = response;
    }

    public int StatusCode { get; set; }
    public String StatusCodeDescription { get; set; }
    public String Request { get; set; }
    public String Response { get; set; }
}

目前我找不到以这种方式工作的 Java 异常示例。上面的异常就是这样调用的

throw new ResponseException(((int)response[1]), 
   ((String)response[2]), url, ((String)response[0]));

我通读了以下主题，但它们没有提供太多关于我将如何解决这个问题的见解，或者是否有可能。

您始终可以创建自定义异常，只需以不同的方式处理它们

class MyException extends Exception {

public int StatusCode;
public String StatusCodeDescription;
public String Request;
public String Response;

public MyException() {
}

public MyException(String msg) {
    super(msg);
}

public MyException(int statusCode, String statusCodeDescription,
        String request, String response) {
    StatusCode = statusCode;
    StatusCodeDescription = statusCodeDescription;
    Request = request;
    Response = response;
}

public int getStatusCode() {
    return StatusCode;
}

public void setStatusCode(int statusCode) {
    StatusCode = statusCode;
}

public String getStatusCodeDescription() {
    return StatusCodeDescription;
}

public void setStatusCodeDescription(String statusCodeDescription) {
    StatusCodeDescription = statusCodeDescription;
}

public String getRequest() {
    return Request;
}

public void setRequest(String request) {
    Request = request;
}

public String getResponse() {
    return Response;
}

public void setResponse(String response) {
    Response = response;
}

}

并使用

throw new MyException(((int)response[1]), ((String)response[2]), url, ((String)response[0]));
