The java.time.LocalDate class represents a date without time (year, month, day) in the ISO-8601 calendar system. It does not include time or timezone information.
Commonly Used Methods
Simple Program
import java.time.LocalDate;
public class SimpleLocalDateExample {
public static void main(String[] args) {
LocalDate today = LocalDate.now();
LocalDate independenceDay = LocalDate.of(1947, 8, 15);
System.out.println("Today's date: " + today);
System.out.println("Indian Independence Day: " + independenceDay);
System.out.println("Day of the week for Independence Day: " + independenceDay.getDayOfWeek());
}
}Problem Statement
Paani and Mahesh are building a customer onboarding system for LoanTrust Bank. The system needs to:
- Capture the customer’s date of birth.
- Calculate the current age using
LocalDateandPeriod. - Determine if the applicant is eligible for an adult loan (age ≥ 21).
import java.time.LocalDate;
import java.time.Period;
import java.util.Scanner;
public class CustomerOnboarding {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// Input customer date of birth
System.out.print("Enter your date of birth (yyyy-mm-dd): ");
String dobInput = scanner.nextLine();
LocalDate dob = LocalDate.parse(dobInput);
LocalDate today = LocalDate.now();
System.out.println("Date of Birth: " + dob);
System.out.println("Today's Date: " + today);
// Calculate age
Period age = Period.between(dob, today);
System.out.println("You are " + age.getYears() + " years old.");
// Eligibility check
if (age.getYears() >= 21) {
System.out.println("You are eligible for an adult loan.");
} else {
System.out.println("You are not eligible. Must be at least 21 years old.");
}
scanner.close();
}
}
/*Enter your date of birth (yyyy-mm-dd): 2003-05-20
Date of Birth: 2003-05-20
Today's Date: 2025-05-22
You are 22 years old.
You are eligible for an adult loan.
*/The LocalDate class is one of the most frequently used types in Java for:
- Representing dates without time or time zones.
- Performing age calculations, determining anniversaries, or validating loan eligibility.
- Seamless integration with
Periodmakes it excellent for date-difference calculations.
Use LocalDate when you only need the year, month, and day component of a date, especially in applications like HR systems, banking, insurance, and education platforms.
