java _io_ converting input stream, the input to the read source file Baidu

You can specify the content of the output character set

Without decorator:
OutputStreamWiter the OutputStreamWriter new new OS = (new new a FileOutputStream ( "D: / D / baidu"), "UTF-. 8"); // character set is not specified, the default character set for the project

加装饰器:
BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(new FileOutputStream("D:/d/baidu"),"UTF-8") );

try(BufferedReader reader=new BufferedReader(new InputStreamReader(new URL("http://www.baidu.com").openStream(),"UTF-8"));
    BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(new FileOutputStream("D:/d/baidu.html"),"UTF-8")); //不指定字符集，默认是工程字符集
        )
{
    String s;
    while((s=reader.readLine())!=null)
    {
        writer.write(s);
        writer.newLine();
        writer.flush();
    }

}catch(IOException e)
{
    System.out.println("操作异常");
}
