我们到底能走多远系列（1）

“我们到底能走多远系列”：开始我的java之路。我要挖出这个地道，离开这里。

IO入门代码阅读：

字节流：

private void writeTxt(String path, String value) throws IOException{        OutputStream fos = new FileOutputStream(path);//构造方法1        fos.write(value.getBytes());        fos.close();    }    private void readTxt(String path) throws IOException{        File file = new File(path);        InputStream fis = new FileInputStream(path);//构造方法2        byte b[] = new byte[(int)file.length()] ;        fis.read(b);        System.out.print(new String(b));        fis.close();    }

字符流：

private void writeTxt(String path, String value) throws IOException{        Writer writer = new FileWriter(path);        writer.write(value);        writer.close();    }        private void readTxt(String path) throws IOException{        Reader reader = new FileReader(path);        char c[] = new char[1024] ;        int len = reader.read(c);        System.out.print(new String(c, 0, len));        reader.close();    }
