Java第十六次作业：使用阿里云提供的API查询天气预报

废话不多说，上代码！

package com.imooc.weather;import com.imooc.weather.impl.WeatherUtilsImpl;import java.util.List;
import java.util.Scanner;public class Application {public static void main(String[] args) {System.out.println("查询最近天气预报：");System.out.println("输入1：查询未来24小时天气预报:");System.out.println("输入2：查询未来3天天气预报");System.out.println("输入3：查询未来7天天气预报");System.out.print("请输入您的选择：");Scanner scanner = new Scanner(System.in);int i = scanner.nextInt();System.out.println("用户输入数字：" + i);if (i==1){System.out.print("请输入城市名称查询未来24小时天气预报：");String city = scanner.next();WeatherUtils weatherUtils = new WeatherUtilsImpl();List weatherList = weatherUtils.w24h("API",city);//API输入自己的api应用程序编程接口，这里就不提供了！System.out.println(weatherList);if (weatherList.size() == 0){System.out.println("抱歉，未收录您查询的城市天气数据。");}else{for (HourWeather hourWeather : weatherList){String template = "%s月%s日%s时|%-3s|%-20s|%-8s|%-4s℃";String row = String.format(template,new String[]{hourWeather.getMonth(),hourWeather.getDay(),hourWeather.getHour(),hourWeather.getWindDirection(),hourWeather.getWindPower(),hourWeather.getWeather(),hourWeather.getTemperature()});System.out.println(row);}}} else if (i==2){System.out.print("请输入城市名称查询未来3天天气预报:");String city = scanner.next();WeatherUtils weatherUtils = new WeatherUtilsImpl();List weatherList = weatherUtils.w3d("api", city);//API输入自己的api应用程序编程接口System.out.println(weatherList.size());if (weatherList.size() == 0) {System.out.println("抱歉，未收录您查询的城市天气数据。");}else{for (DayWeather weather : weatherList){String template = "%-2s月%-2s日 | 气温: %s℃(日) %s℃(夜) | 天气: %s(日) %s(夜) | 风力: %s(日) %s(夜)";String row = String.format(template,new String[]{weather.getMonth(),weather.getDay(),weather.getDayAirTemperature(),weather.getNightAirTemperature(),weather.getDayWeather(),weather.getNightWeather(),weather.getDayWindPower(),weather.getNightWindPower()});System.out.println(row);}}}else if (i==3) {System.out.print("请输入城市名称查询未来7天天气预报:");String city = scanner.next();WeatherUtils weatherUtils = new WeatherUtilsImpl();List weatherList = weatherUtils.w7d("api", city);//API输入自己的api应用程序编程接口System.out.println(weatherList.size());if (weatherList.size() == 0) {System.out.println("抱歉，未收录您查询的城市天气数据。");} else {for (DayWeather weather : weatherList) {String template = "%-2s月%-2s日 | 气温: %s℃(日) %s℃(夜) | 天气: %s(日) %s(夜) | 风力: %s(日) %s(夜)";String row = String.format(template, new String[]{weather.getMonth(),weather.getDay(),weather.getDayAirTemperature(),weather.getNightAirTemperature(),weather.getDayWeather(),weather.getNightWeather(),weather.getDayWindPower(),weather.getNightWindPower()});System.out.println(row);}}}}}

代码结果

  7~10日气温过低，多加衣物，以防感冒！

拜拜
