How to generate a Date from just Month and Year in Java?

Question

I need to generate a new Date object for credit card expiration date, I only have a month and a year, how can I generate a Date based on those two? I need the easiest way possib

Answer 1

java.time

Using java.time framework built into Java 8

import java.time.YearMonth;

int year = 2015;
int month = 12;
YearMonth.of(year,month); // 2015-12

from String

YearMonth.parse("2015-12"); // 2015-12

with custom DateTimeFormatter

import java.time.format.DateTimeFormatter;

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM yyyy");
YearMonth.parse("12 2015", formatter); // 2015-12

Conversions To convert YearMonth to more standard date representation which is LocalDate.

LocalDate startMonth = date.atDay(1); //2015-12-01
LocalDate endMonth = date.atEndOfMonth(); //2015-12-31
