How to convert Shift-JIS to UTF-8 in Java

This is a rudimentary question.My current original file is SJIS.So, I want to display Japanese kanji on the Linux screen.
My current Java source code is:

private static String convertUTF8ToShiftJ(String uft8Stg){
    String is = null;
    String shftJStrg = null;

    try{
        byte [] bt = uft8Strg.getBytes (StandardCharsets.UTF_8);
        is = new String(bt, "SHIFT-JIS");
        shftJStr = new String(is);
        logger.info("Converted to the string:"+shftJStrg);
        System.out.println(shftJStrg);
    } catch(Exceptione){
        e.printStackTrace();
        return uft8Strg;
    }

    return shftJStrg;
}

In , the results displayed on the Linux screen are:

***UX0025.SH 開Started ）
*** UX0025.SH � (executing...ec)
*** UX0025.SH 終Endedﾂ

However, the actual results you want to see are:

***UX0025.SH Start (started)
*** UX0025.SH Running...
*** UX0025.SH Ended

I'm in trouble because I don't know where my code is wrong.
Does anyone know?It's helpful.

The proposed convertUTF8ToShiftJ() uses the Unicode string as input and encodes it into the UTF-8 byte string, forcing it to be decoded as shift JIS and returning it to Unicode.Non-ASCII characters will be corrupted.

Java String is always Unicode, so

Specify that the stream should be decoded as shift JIS when reading the file
Specify that the stream is encoded as UTF-8 during file or screen output

This should be the expected behavior.
