Java读取txt文件中的数据赋给String变量方法

public class MainActivity {

     private static final String fileName = "D:/Tao/MyEclipseWorkspace/resources/weather.txt" ;

     public static void main(String[] args) {

         //读取文件

         BufferedReader br = null ;

         StringBuffer sb = null ;

         try {

             br = new BufferedReader( new InputStreamReader( new FileInputStream(fileName), "GBK" )); //这里可以控制编码

             sb = new StringBuffer();

             String line = null ;

             while ((line = br.readLine()) != null ) {

                 sb.append(line);

             }

         } catch (Exception e) {

             e.printStackTrace();

         } finally {

             try {

                 br.close();

             } catch (Exception e) {

                 e.printStackTrace();

             }  

         }

         String data = new String(sb); //StringBuffer ==> String

         System.out.println( "数据为==> " + data);

     }

}
