Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to sort a sequence of numbers in reverse order using selection sort.Problem Statement:Write 8085 Assembly language program to sort a given sequence using selection sort in descending order. The numbers are stored at 8001H onwards. 8000H is holding the block size.Discussion:In the selection sorting technique, we will choose the minimum or the maximum term from a set of numbers. In this case we are considering the sorting in descending order, so we are choosing the maximum number. By taking the maximum number, we ... Read More
The name of the provider can be obtained using the getName() method in the class java.security.Provider. This method requires no parameter and it returns the name of the provider as required.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) { try { KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance("DSA"); Provider p = kpGenerator.getProvider(); System.out.println("The Provider is: " + p.getName()); } catch (NoSuchAlgorithmException e) { ...

To get the average string length in MySQL, we will work around a query that gets rows from 1 to 10 and displays the result.Let us first create a table. The query to create a table is as follows −mysql> create table AverageString -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Value varchar(20) -> ); Query OK, 0 rows affected (0.66 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into AverageString(Value) values('MySQL Query'); Query OK, 1 row ... Read More
The CallableStatement interface provides methods to execute the stored procedures. Since the JDBC API provides a stored procedure SQL escape syntax, you can call stored procedures of all RDBMS in single standard way.Creating a CallableStatementYou can create an object of the CallableStatement (interface) using the prepareCall() method of the Connection interface. This method accepts a string variable representing a query to call the stored procedure and returns a CallableStatement object.A Callable statement can have input parameters, output parameters or both. To pass input parameters to the procedure call you can use place holder and set values to these using the ... Read More

First of all, you need to get your collection with the help of getCollectionNames().The database name is “test”. Let us loop through all MongoDB collections and execute the query. The query is as follows −> db.getCollectionNames().forEach(function(collectioNameDemo) ... { ... var nextDemo = db[(collectioNameDemo) ].find().sort({_id:-1}).limit(1); ... if (nextDemo.hasNext()) ... { ... printjson(nextDemo.next()._id.getTimestamp()); ... } ... });The following is the output −ISODate("2019-02-21T18:52:43Z") ISODate("2019-03-19T17:49:00Z") ISODate("2019-03-06T15:40:12Z") ISODate("2019-03-15T16:31:50Z") ISODate("2019-02-21T15:40:52Z") ISODate("2019-03-06T06:14:37Z") ISODate("2019-02-21T19:29:15Z") ISODate("2019-03-15T13:35:33Z") ISODate("2019-03-14T21:13:58Z") ISODate("2019-03-18T22:02:54Z") ISODate("2019-03-22T18:01:45Z") ISODate("2019-03-06T16:21:14Z") ISODate("2019-02-20T15:04:32Z") ISODate("2019-03-06T07:45:42Z") ISODate("2019-03-19T12:33:17Z") ISODate("2019-03-20T21:39:21Z") ISODate("2019-03-15T16:44:26Z") ISODate("2019-03-22T06:20:45Z") ISODate("2019-02-21T16:40:55Z") ISODate("2019-02-21T12:45:20Z") ISODate("2019-03-06T16:05:48Z") ISODate("2019-03-06T16:00:08Z") ISODate("2019-02-28T12:43:56Z") ISODate("2019-03-20T22:11:41Z") ISODate("2019-03-06T05:56:45Z") ISODate("2019-03-06T07:34:12Z") ISODate("2019-03-14T21:00:16Z") ISODate("2019-02-28T10:33:39Z") ISODate("2019-03-06T05:11:10Z") ISODate("2019-02-28T09:44:28Z") ISODate("2019-03-06T10:13:22Z") ISODate("2019-03-17T21:35:26Z")Read More

In this tutorial we will be focussing on how to send text message from your iOS application in Swift, where we will be sending a text message from your user’s phone number. While we cannot do this directly without the content of your user’s but we can display a precomposed message for the user to send which user can modify later if he wants to.So let’s get started, We will be using “MFMessageComposeViewController” class object to display the standard message composition interface inside your application.Before we present the composition interface, we will populate the fields with the basic initial message ...
