Answer 1

you can use Calendar.getInstance().get(Calendar.MONTH);
to get the current month (since the seasons depend on the month, unless you want to be precise and use also the day ) and put it into a switch, so that in case 0, 1 and 11 it's winter, case 2, 3, 4 spring and so on.... remember that the months are 0 -based so January will be 0 and not 1
