實例如下所示：
public class MainActivity {private static final String fileName = "D:/Tao/MyEclipseWorkspace/resources/weather.txt";public static void main(String[] args) {//讀取文件BufferedReader br = null;StringBuffer sb = null;try {br = new BufferedReader(new InputStreamReader(new FileInputStream(fileName),"GBK")); //這裡可以控制編碼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("數據為==> " + data);}}以上這篇Java讀取txt文件中的數據賦給String變量方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林網。
