Answer 1

To convert a month integer to a String, you can do:

String month = new java.text.DateFormatSymbols().months[ 4 ]

assert month == 'May'

Answer 2

Consider these three ways of doing that, I hope these will help you.

1)you can do as below by giving month as integer

import java.text.DateFormatSymbols;
public String getMonth(int month) {
return new DateFormatSymbols().getMonths()[month-1];
}

2)you can do as below by giving date

SimpleDateFormat dateFormat = new SimpleDateFormat( "LLLL", Locale.getDefault() );
dateFormat.format( date );

3)Using SimpleDateFormat.

import java.text.SimpleDateFormat;

public String formatMonth(String month) {
SimpleDateFormat monthParse = new SimpleDateFormat("MM");
SimpleDateFormat monthDisplay = new SimpleDateFormat("MMMM");
return monthDisplay.format(monthParse.parse(month));
}
formatMonth("2"); //Result: February
