问将byte[]写入文件并从文件读取byte[]

EN

import java.io.*;

public class test{
    public static void main(String argv[]){
        try{
            byte[] Write = "1234567812345678".getBytes();
            byte[] Read = new byte[16];

            File test_file = new File("test_file");
            test_file.mkdir();

            String path = new String(test_file.getAbsolutePath()+"\\"+"test.txt");
            File test_out = new File(path);
            test_out.createNewFile();

            BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(test_out));
            out.write(Write);
            out.close();

            File test_in = new File(path);
            BufferedInputStream in = new BufferedInputStream(new FileInputStream(test_in));
            while(in.available()>0)
                in.read(Read);
            in.close();

            System.out.println(Write);
            System.out.println(Read);
        }catch ( Exception e ){
            e.printStackTrace();
        }
    }
}
