How to List All Months Between Two Dates in Java?

Listing Months Between Two Dates

Determining the months between two specified dates can be a challenging task. To accomplish this, we delve into a Java-centric approach, employing the intuitive Java 8 Date API.

The first step involves parsing the input dates into Java 8 LocalDate objects. We then initialize a Month instance corresponding to the start date.

Next, we iterate through the months until we reach the end date. Within each iteration, we capture the format of the month and year to build the desired list.

Below is a code snippet that comprehensively addresses this task:

<code class="java">import java.time.LocalDate;
import java.time.Month;
import java.util.ArrayList;
import java.util.List;

class MonthLister {
  public static void main(String[] args) {
    // Parse input dates
    LocalDate startDate = LocalDate.parse("2010-12-02");
    LocalDate endDate = LocalDate.parse("2012-05-06");

    // Initialize current month
    Month currentMonth = startDate.getMonth();

    // Create list to store months
    List<String> months = new ArrayList<>();

    // Iterate through months until end date is reached
    while (!currentMonth.equals(endDate.getMonth())) {
      // Capture format of month and year
      months.add(currentMonth.toString() + "-" + startDate.getYear());

      // Increment current month
      startDate = startDate.plusMonths(1);
      currentMonth = startDate.getMonth();
    }

    // Output list of months
    months.forEach(System.out::println);
  }
}</code>

In this snippet, the encapsulation of code within the MonthLister class enhances its reusability and maintainability. The main method orchestrates the date parsing, month iteration, and list formation. The output is a neatly formatted list of months between the specified dates.
