Formatting MMyyyy to MMyy

The following is my sample code:

String month = "09";

String year = "2014";

String monthYear = "092014";

The monthYear format is MMyyyy, I wish to format it to become MMyy. Thus, I am doing it as follows:

Method 1:

final SimpleDateFormat oriMonthYear = new SimpleDateFormat( "MMyyyy" );
final SimpleDateFormat changeMonthYear = new SimpleDateFormat( "MMyy" );

String newMonthYear = changeMonthYear.format( oriMonthYear.parse( month + year) );

This give me correct output, but I am not sure am I doing it by stupid way or not. I believe it should be another best practice and smart to way to do it.

We can use YearMonth in Java 8 or later like below:
YearMonth
.parse(yearMonth, DateTimeFormatter.ofPattern(MMYYYY))
.format(DateTimeFormatter.ofPattern(MMYY));
