实例如下所示：
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 ==> StringSystem.out.println("数据为==> " + data);}}以上这篇Java读取txt文件中的数据赋给String变量方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持武林网。
