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 ...

An immutable copy of a LocalTime with the seconds altered as required is done using the method withSecond() in the LocalTime class in Java. This method requires a single parameter i.e. the second that is to be set in the LocalTime and it returns the LocalTime with the second altered as required.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main { public static void main(String[] args) { LocalTime lt1 = LocalTime.parse("23:15:30"); System.out.println("The LocalTime is: " + lt1); LocalTime lt2 = lt1.withSecond(45); ...

Let us first create a collection with the document. The query to create a collection with a document is as follows −> db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"John", "StudentLastName":"Smith", "StudentAge":23}); { "acknowledged" : true, "insertedId" : ObjectId("5c8ac3a96cea1f28b7aa080d") } > db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"Carol", "StudentLastName":"Tayor", "StudentAge":24}); { "acknowledged" : true, "insertedId" : ObjectId("5c8ac3bc6cea1f28b7aa080e") } > db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"David", "StudentLastName":"Miller", "StudentAge":21}); { "acknowledged" : true, "insertedId" : ObjectId("5c8ac3ce6cea1f28b7aa080f") } > db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"Bob", "StudentLastName":"Taylor", "StudentAge":20}); { "acknowledged" : true, "insertedId" : ObjectId("5c8ac3e16cea1f28b7aa0810") } > db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"Robert", "StudentLastName":"Smith", "StudentAge":20}); { "acknowledged" : true, "insertedId" : ObjectId("5c8ac3fb6cea1f28b7aa0811") } > db.aggregationFrameworkWithOrMatchDemo.insertOne({"StudentFirstName":"Mike", "StudentLastName":"Miller", ...

To insert element into the stream, you need to use the add() method of the IntStream.Builder.The syntax is as follows:default IntStream.Builder add(int t)Here, parameter t is the element to be inserted.Declare IntStream.Builder:IntStream.Builder builder = IntStream.builder();Add some elements to the Builder using add() method:builder.add(10); builder.add(25); builder.add(33); builder.add(42);The following is an example to implement IntStream.Builder add() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo { public static void main(String[] args) { IntStream.Builder builder = IntStream.builder(); System.out.println("Elements in the stream..."); builder.add(10); builder.add(25); builder.add(33); builder.add(42); ...

In this article, we will see what is the conversion operator in C++. C++ supports object-oriented design. So we can create classes of some real-world objects as concrete types.Sometimes we need to convert some concrete type objects to some other type objects or some primitive datatypes. To make this conversion we can use conversion operator. This is created like operator overloading function in class.In this example, we are taking a class for complex numbers. It has two arguments real and imaginary. When we assign the object of this class into some double type data, it will convert into its magnitude ... Read More
Assume that the date is in varchar data type i.e. not in the date format.Let us first create a table. Following is the query −mysql> create table convertDateDemo -> ( -> AdmissionDate varchar(200) -> ); Query OK, 0 rows affected (0.63 sec)Following is the query to insert some records in the table using insert command −mysql> insert into convertDateDemo values('April 04 2019'); Query OK, 1 row affected (0.18 sec) mysql> insert into convertDateDemo values('May 05 2018'); Query OK, 1 row affected (0.16 sec) mysql> insert into convertDateDemo values('January 01 2012'); Query OK, 1 row affected ...

To create a tab delimited select statement, you can use CONCAT() function from MySQL. Following is the syntax:select concat(yourColumnName1, "\t", yourColumnName2) AS anyAliasName from yourTableName;Let us first create a table:mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, FirstName varchar(20), LastName varchar(20) ); Query OK, 0 rows affected (0.81 sec)Following is the query to insert records in the table using insert command:mysql> insert into DemoTable(FirstName, LastName) values('John', 'Smith'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable(FirstName, LastName) values('Carol', 'Taylor'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable(FirstName, LastName) ...

The service that can describe the implementation of a Provider in regards to any algorithm is obtained using the method getService() in the class java.security.Provider. This method requires two parameters i.e. the service type required and the algorithm name of the required service.A program that demonstrates this is given as follows −Example Live Demoimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) throws Exception { try { Signature sign = Signature.getInstance("SHA256withDSA"); Provider p = sign.getProvider(); Provider.Service s = p.getService("Signature", sign.getAlgorithm()); ...
