java天气预报源代码 java天气接口
大家好 我刚才在写java天气预报 我用json解析的数据怎样放到java界面？
可以在JFrame中添加几个Label控件或其他文本控件用来展示解析出来的结果

java调天气预报
①取出地址中的返回值（getWeatherReader方法）
②解析json格式的字符串
③形成你要展示的天气预报效果
public static String getWeatherReader() {//取得接口字符串
String currentLine = "";
String strReturn = "";
URL url = null;
HttpURLConnection conn = null;
InputStream in = null;
BufferedReader buff = null;
try {
url = new URL("");
System.out.println(url.toURI());
//打开地址链接
conn = (HttpURLConnection)url.openConnection();
conn.connect();
//接收数据
in = conn.getInputStream();
//如有乱码注意编码方式，如：UTF-8
buff = new BufferedReader(new InputStreamReader(in, "gb2312"));
while((currentLine = buff.readLine()) != null) {
strReturn += currentLine;
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
in.close();
buff.close();
} catch (IOException e) {
return "8EF0000";
}
}
return strReturn;
}
java调用天气预报api怎么写
//通过中国天气api调用
