To change a specific char in a MySQL string, you can use CONCAT() along with SUBSTRING().Let us first create a table −mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Value varchar(200) ); Query OK, 0 rows affected (0.60 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(Value) values('98764'); Query OK, 1 row affected (0.17 sec)Following is the query to display all records from the table using select statement −mysql> select *from DemoTable;This will produce the following output −+----+-------+ | Id | Value | +----+-------+ | 1 | 98764 | +----+-------+ ...

Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to add the contents of N word locations.Problem Statement:Write 8085 Assembly language program to add N 16-bit numbers stored into memoryDiscussion:The 16-bit numbers are stored into memory location 8001H onwards. The value of N is stored at location 8000H. After addition, the result will be stored at location 8050H onwards.In 8085 we have few number of registers. So we are storing the count into memory, when we need to update it, we will fetch it from memory, update it and then again store ... Read More
The version number of the provider can be obtained using the method getVersion() in the class java.security.Provider. This method requires no parameter and it returns the version number 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 version number is: " + p.getVersion()); } catch (NoSuchAlgorithmException e) { ...

Dynamic channel allocation are schemes for allotting shared network channels to competing users in a dynamic manner as per their requirements. The users may be base stations, access points or terminal equipment which are allotted channels from a central pool. There are a number of methods for dynamic channel allocation. The key assumptions of these methods are −Independent Traffic − It is assumed that the users are independent of each other, i.e. each user has to send or receive data which is independent of the data transmission of the other users in the network system. Each user has a program ... Read More
Before getting into example, we should know what sqlite data base in android is. SQLite is an open source SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features. In order to access this database, you don't need to establish any kind of connections for it like JDBC, ODBC etc.This example demonstrate about How to use now in timestamp in Android sqlite.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details ...

An immutable copy of a instant where some milliseconds are added to it can be obtained using the plusMillis() method in the Instant class in Java. This method requires a single parameter i.e. the number of milliseconds to be added and it returns the instant with the added milliseconds.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { Instant i = Instant.now(); System.out.println("The current instant is: " + i); System.out.println("An instant with 60000 milliseconds added is: " + ...
