1. Introduction

Java 8 added a new set of packages to provide a comprehensive date-time model. Java 8 Date-Time API is a JSR-310 implementation.

 
 
 
 
 
 
 
 

 

There are several interfaces: ChronoLocalDate, ChronoLocalDateTime, ChronoZonedDateTime in java.time.chrono packages. They all have isBefore, isAfter, isEquals, and compareTo methods to compare two dates.

Java 8 date classes: java.time.LocalDate, java.time.LocalDateTime, java.time.Instant, java.time.ZonedDateTime, java.time.chrono.JapaneseDate, java.time.chrono.MinguoDate, etc implement these interfaces.

In this example, I will demonstrate how to compare dates with these date classes.

2. Technologies Used

The example code in this article was built and run using:

  • Java 1.8.101
  • Maven 3.3.9
  • Eclipse Oxygen
  • JUnit 4.12

3. Maven Project

3.1 Dependency

Add JUnit to the pom.xml.

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

			</plugin>
		</plugins>
	</build>
</project>

3.2 Domain Model

I will define a Fruit class which contains an in-stock date, id, and name attributes. I will demonstrate how to find, filter, and sort objects based on the in-stock date.

fruit.java

package com.zheng.demo.domain;

import java.time.LocalDate;

public class Fruit {

	private int id;
	private String name;
	private LocalDate instockDate;

	public Fruit(int id, String name, LocalDate instockDate) {
		super();
		this.id = id;
		this.name = name;
		this.instockDate = instockDate;

	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public LocalDate getInstockDate() {
		return instockDate;
	}

	public void setInstockDate(LocalDate instockDate) {
		this.instockDate = instockDate;
	}

	@Override
	public String toString() {
		return "Fruit [id=" + id + ", name=" + name + ", instockDate=" + instockDate + "]";
	}

}

4. JUnit Tests

I will use JUnit test classes to demonstrate how to compare two dates for a different date classes.

4.1 DateCompareTest

public class DateCompareTest {

	private Date copyFromNow;
	private Date now;
	private Date secondLater;

	@Test
	public void after() {
		assertTrue(secondLater.after(now));
	}

	@Test
	public void before() {
		assertTrue(now.before(secondLater));
		assertFalse(secondLater.before(now));
	}

	@Test
	public void compareTo() {
		int diff = secondLater.compareTo(now);
		assertTrue(diff > 0);

		diff = now.compareTo(secondLater);
		assertTrue(diff < 0);

		diff = now.compareTo(copyFromNow);
		assertTrue(diff == 0);
	}

	@Test
	public void equals() {
		assertTrue(now.equals(copyFromNow));
	}

	@Before
	public void setup() {
		now = new Date();
		copyFromNow = new Date(now.getTime());
		System.out.println("now:" + now);
		try {
			Thread.sleep(1000);
		} catch (InterruptedException e) {

		}

		secondLater = new Date();

	}

}

	private Instant copyFromNow;
	private Instant now;
	private Instant secondLater;

	@Test
	public void compareTo() {	
		assertTrue(now.compareTo(secondLater)  0);		
		assertTrue( now.compareTo(copyFromNow) == 0);
	}

	@Test
	public void equals() {
		assertTrue(now.equals( copyFromNow));
	}

	@Test
	public void isAfter() {	
		assertFalse(now.isAfter(secondLater));
		assertTrue(secondLater.isAfter(now));
	}
	
	@Test
	public void isBefore() {

		assertFalse(secondLater.isBefore(now));
	}
	
	@Before
	public void setup() {

		copyFromNow = Instant.from(now);
		secondLater = now.plusSeconds(1);
		System.out.println("now:" + now);
