It can be checked if the LocalDate is in a leap year or not using the isLeapYear() method in the LocalDate class in Java. This method requires no parameters. It returns true if the LocalDate is in a leap year and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalDate ld = LocalDate.parse("2012-10-12");       System.out.println("The LocalDate is: " + ld);       boolean flag = ld.isLeapYear();       if(flag)          System.out.println("This is a leap ...

It can be checked if two LocalDate objects are equal or not using the isEqual() method in the LocalDate class in Java. This method requires a single parameter i.e. the LocalDate object that is to be compared. It returns true if the two LocalDate objects are equal and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalDate ld1 = LocalDate.parse("2019-02-12");       LocalDate ld2 = LocalDate.parse("2019-02-12");       System.out.println("The LocalDate ld1 is: " + ld1);       System.out.println("The ...

It can be checked if a particular LocalDate is before the other LocalDate in a timeline using the isBefore() method in the LocalDate class in Java. This method requires a single parameter i.e. the LocalDate object that is to be compared. It returns true if the LocalDate object is before the other LocalDate object and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalDate ld1 = LocalDate.parse("2019-02-12");       LocalDate ld2 = LocalDate.parse("2019-02-14");       System.out.println("The LocalDate ld1 is: ...

It can be checked if a particular LocalDate is after the other LocalDate in a timeline using the isAfter() method in the LocalDate class in Java. This method requires a single parameter i.e. the LocalDate object that is to be compared. It returns true if the LocalDate object is after the other LocalDate object and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main {    public static void main(String[] args) {       LocalDate ld1 = LocalDate.parse("2019-02-20");       LocalDate ld2 = LocalDate.parse("2019-02-14");       System.out.println("The LocalDate ld1 is: ...

It can be checked if a particular Instant object is after the other Instant object in a timeline using the isAfter() method in the Instant class in Java. This method requires a single parameter i.e. the Instant object that is to be compared. It returns true if the Instant object is after the other Instant object and false otherwise.A program that demonstrates this is given as followsExample Live Demoimport java.time.*; import java.time.temporal.ChronoUnit; public class Demo {    public static void main(String[] args) {       Instant i1 = Instant.parse("2019-01-13T16:10:35.00Z");       Instant i2 = Instant.parse("2019-01-13T11:19:28.00Z");       boolean ...

An immutable copy of a Period with the number of days as required is done using the method withDays() in the Period class in Java. This method requires a single parameter i.e. the number of days in the Period and it returns the Period with the number of days as required.A program that demonstrates this is given as followsExample Live Demoimport java.time.Period; public class Demo {    public static void main(String[] args) {       String period = "P5Y7M15D";       Period p1 = Period.parse(period);       System.out.println("The Period is: " + p1);       Period p2 ...

To get the string representation of the CopyOnWriteArrayList, use the toString() method in Java.The syntax is as followsString toString()To work with CopyOnWriteArrayList class, you need to import the following packageimport java.util.concurrent.CopyOnWriteArrayList;The following is an example to implement CopyOnWriteArrayList class toString() method in JavaExample Live Demoimport java.util.concurrent.CopyOnWriteArrayList; public class Demo { public static void main(String[] args) { CopyOnWriteArrayList arrList = new CopyOnWriteArrayList(); arrList.add(100); arrList.add(250); arrList.add(0, 400); arrList.add(1, 500); arrList.add(2, 650); arrList.add(700); arrList.add(800); System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString()); } }OutputCopyOnWriteArrayList String Representation = [400, 500, 650, 100, 250, 700, 800]

An immutable copy of a Period with the number of years as required is done using the method withYears() in the Period class in Java. This method requires a single parameter i.e. the number of years in the Period and it returns the Period with the number of years as required.A program that demonstrates this is given as followsExample Live Demoimport java.time.Period; public class Demo {    public static void main(String[] args) {       String period = "P5Y7M15D";       Period p1 = Period.parse(period);       System.out.println("The Period is: " + p1);       Period p2 ...
