大家好 我剛才在寫(xiě)java天氣預(yù)報(bào) 我用json解析的數(shù)據(jù)怎樣放到j(luò)ava界面？

可以在JFrame中添加幾個(gè)Label控件或其他文本控件用來(lái)展示解析出來(lái)的結(jié)果

java調(diào)天氣預(yù)報(bào)

①取出地址中的返回值（getWeatherReader方法）

②解析json格式的字符串

③形成你要展示的天氣預(yù)報(bào)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());

//打開(kāi)地址鏈接

conn = (HttpURLConnection)url.openConnection();

conn.connect();

//接收數(shù)據(jù)

in = conn.getInputStream();

//如有亂碼注意編碼方式，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;

}
