Use byte stream to read Chinese from file to console display

package text;

import java.io.FileInputStream;
import java.io.IOException;


public class FileInputStreamDemo06 {
    public static void main(String[] args) throws IOException {
        FileInputStream fis = new FileInputStream("D:\\a.txt");
        int len;
        byte[] bytes = new byte[70];
        while ((len = fis.read(bytes)) != -1) {
            System.out.print(new String(bytes, 0, len, "gbk"));
        }
        fis.close();
    }

}

Tips ：idea By default utf-8 Coded ,utf-8 code 1 Chinese accounts for 3 Bytes ,gbk code 1 Chinese accounts for 2 Bytes . Using byte stream to read Chinese data adopts the method of reading one byte at a time , So what you read is garbled . When we use Notepad to store Chinese, the default is ANSI code , In fact, that is GBK code
