java - 将 For 循环与 Weather Java Web 服务结合使用

Question

我编写了一种从 WSDL Web 服务获取天气详细信息的方法。我的代码工作正常，没有任何错误，但是有没有办法使用 For 循环/while 从用户那里获取三个城市和邮政编码？

程序应使用“for/while 循环”提示第二个、第三个和更多城市的相同信息。

我该怎么做？

这是 WSDL 文件:

`http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

这是我的代码:

package weather;

import com.cdyne.ws.weatherws.ArrayOfWeatherDescription;
import com.cdyne.ws.weatherws.WeatherReturn;
import java.util.Scanner;

/**
 *
 * @author elacy
 */
public class Weather {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
      try {
        String zipCode1;
        String zipCode2;
        String zipCode3;
        Scanner keyboard = new Scanner(System.in);
        String City1;
        String City2;
        String City3;

        com.cdyne.ws.weatherws.Weather service = new com.cdyne.ws.weatherws.Weather();
        com.cdyne.ws.weatherws.WeatherSoap port = service.getWeatherSoap();

        \\makes this part a For loop

        System.out.println ("Please enter your First city");
        City1 = keyboard.nextLine().toUpperCase();
        System.out.println ("Please enter your First zipcode");
        zipCode1 = keyboard.nextLine();
        System.out.println ("Please enter your Second city");
        City2 = keyboard.nextLine().toUpperCase();
        System.out.println ("Please enter your Second zipcode");
        zipCode2 = keyboard.nextLine();
        System.out.println ("Please enter your Third city");
        City3 = keyboard.nextLine().toUpperCase();
        System.out.println ("Please enter your Third zipcode");
        zipCode3 = keyboard.nextLine();

        System.out.println("------------------------------------------------------");
        System.out.println("EVAN'S WEATHER FORECAST FOR: SUNDAY, OCTOBER 07, 2013");
        System.out.println("------------------------------------------------------");
        System.out.println("City   Zip   Code    Temp   Relative   Humidity");

       System.out.println(City1 +"   "+ zipCode1 + 
       port.getCityWeatherByZIP(zipCode1).getTemperature() +
       port.getCityWeatherByZIP(zipCode1).getRelativeHumidity());

       System.out.println(City2 +"   "+ zipCode2 +  
       port.getCityWeatherByZIP(zipCode2).getTemperature() +  
       port.getCityWeatherByZIP(zipCode2).getRelativeHumidity());

       System.out.println(City3 +"   "+ zipCode1 +
       port.getCityWeatherByZIP(zipCode3).getTemperature() +
       port.getCityWeatherByZIP(zipCode3).getRelativeHumidity());

       } catch (Exception ex) {
       }

     }

     private static WeatherReturn getCityWeatherByZIP(java.lang.String zip) {
       com.cdyne.ws.weatherws.Weather service = new com.cdyne.ws.weatherws.Weather();
       com.cdyne.ws.weatherws.WeatherSoap port = service.getWeatherSoap();
       return port.getCityWeatherByZIP(zip);
     }        
  }

Answer 1

非常简单:

String[] cities = new String[3];
String[] zipCodes = new String[3];

for (int i = 0; i < 3; i++) {
    System.out.println ("Please enter your City No." + (i + 1) + ":");
    cities[i] = keyboard.nextLine().toUpperCase();
    System.out.println ("Please enter your Zipcode No." + (i + 1) + ":");
    zipCodes[i] = keyboard.nextLine();
}

System.out.println("------------------------------------------------------");
System.out.println("EVAN'S WEATHER FORECAST FOR: SUNDAY, OCTOBER 07, 2013");
System.out.println("------------------------------------------------------");
System.out.println("City   Zip   Code    Temp   Relative   Humidity");

for (int i = 0; i < 3; i++) {
    System.out.println(cities[i] +" " + zipCodes[i] + 
                    port.getCityWeatherByZIP(zipCodes[i]).getTemperature() + 
                    port.getCityWeatherByZIP(zipCodes[i]).getRelativeHumidity());
}
