字符输入流与字符输出流

字符输入流

public class CharSetTest00 {
    public static void main(String[] args) throws Exception{
        //代码UTF-8 文件GBK "D:\\resources\\data.txt"
        //1.  提取GBK文件的原始字节流

        InputStream is = new FileInputStream("D:\\resources\\data.txt");
        //2.  把原始字节流转换成字符输出流
        //Reader isr = new InputStreamReader(is);//默认以UTF-8 转化成字符流, 还是会乱码
        Reader isr = new InputStreamReader(is,"GBK");// 以指定的GBK编码转换成字符输入流
    }
}

字符输出流

public class OutputStreamWriterDemo02 {
    public static void main(String[] args) throws Exception{
        //定义一个原始字节输出流
        OutputStream os = new FileOutputStream("D:\\resources\\data.txt");

        //把原始的字节输出流转换成字符输出流
        Writer osw = new OutputStreamWriter(os,"GBK");//指定GBK方式写字符出去
        //把低级的字符输出流 包装成高级的缓冲字符输出流
        BufferedWriter bw = new BufferedWriter(osw);
    }
