Remember a file transcoding and binary viewing learning

Require:

Chinese characters: GBK internal code

Western: ASCII code

Spacer:

/**
     * field separator
     */
    private static final String FIELD_INTERVAL = new String(new byte[]{0x01});

    /**
     * line separator
     */
    private static final String LINE_INTERVAL = new String(new byte[] {0x0A});

　　

Transcoding: (to convert Western text to ASCII code)

private void appendWithAscii(StringBuilder builder, Object... value) {
　　for (Object object : value) {
　　　　if (object != null) {
　　　　　　builder.append(getAscii(String.valueOf(object)));
　　　　}
　　　　builder.append(FIELD_INTERVAL);
　　}
}


private String getAscii(String input) {
        byte[] asciiByte = input.getBytes(Charsets.US_ASCII);
        return new String(asciiByte);
    }

　　

　　

Write a file in binary form in GBK mode:

/**
     * write in binary
     * @param fileName
     * @param content
     * @param encoding
     * @return
     */
    public static boolean writeFileBinary (String fileName, String content, String encoding) {
        boolean flag = false;
        DataOutputStream out = null;
        try {
            out = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(fileName)));
            byte[] contentByte = content.getBytes(encoding);
            out.write(contentByte);
            flag = true;
        } catch (IOException e) {
        } finally {
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                }
            }
            
        }
        
        return flag;
    }

Where 01 is 0x01, corresponding to the above field separator (field separator)

       0A is 0x0A, corresponding to the line spacer above
