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