How can I increment a date by one day in Java?

Question

I\'m working with a date in this format: yyyy-mm-dd.

How can I increment this date by one day?

Answer 1

java.time

On Java 8 and later, the java.time package makes this pretty much automatic. (Tutorial)

Assuming String input and output:

import java.time.LocalDate;

public class DateIncrementer {
  static public String addOneDay(String date) {
    return LocalDate.parse(date).plusDays(1).toString();
  }
}
