public static void main(String[] args) throws IOException { // TODO Auto-generated method stub InputStream in = null; File f = new File("D:/test.txt"); byte[] b = new byte[2]; in = new FileInputStream(f); int i = 0; while ((i = in.read(b)) != -1) { String str = new String(b); System.out.print(str); } }
12行,数组b里缓存的数据在input的过程中不断变化,那么字符串str怎么能获取读入的所有数据呢?
