字节输入流转换为字符输入流

转换后就可以像字符输入流一样操作

public static void testInputStreamReader(){
   try {
        FileInputStream fileInputStream = new FileInputStream("D:/test.txt");
        InputStreamReader inputStreamReader = new InputStreamReader(fileInputStream,"GBK");
        char[] chars = new char[10];
        int len =0;
        while((len = inputStreamReader.read(chars))!= -1){
            System.out.println(new String(chars,0,len));
        }
        inputStreamReader.close();
        fileInputStream.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

}
