You can use AS command for alias to show tables in MySQL result. Following is the syntax −SELECT TABLE_NAME AS anyAliasName FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = DATABASE();Let us implement the above syntax −mysql> SELECT TABLE_NAME AS MY_TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = DATABASE();This will produce the following output −+------------------------------------+ | MY_TABLE_NAME | +------------------------------------+ | a | | accumulateddemo | | add10minutedemo ...

An int array for the buffer can be obtained using the method array() in the class java.nio.IntBuffer. If the returned array is modified, then the contents of the buffer are also similarly modified and vice versa. If the buffer is read-only, then the ReadOnlyBufferException is thrown.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { IntBuffer buffer = IntBuffer.allocate(n); buffer.put(8); buffer.put(1); ...

The provider for the SecureRandom object can be obtained using the method getProvider() in the class java.security.SecureRandom. This method requires no parameters and it returns the provider for the SecureRandom object.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 { SecureRandom sRandom = SecureRandom.getInstance("SHA1PRNG"); Provider provider = sRandom.getProvider(); System.out.println("The Provider is: " + provider.getName()); } catch (NoSuchAlgorithmException e) { ...

Before getting into an example, we should know what singleton design pattern is. A singleton is a design pattern that restricts the instantiation of a class to only one instance. Notable uses include controlling concurrency and creating a central point of access for an application to access its data store.This example demonstrates How to use Android Media Player SingletonStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, ... Read More
You can achieve this with the help of GROUP BY HAVING clause. The syntax is as follows −SELECT yourColumnName1, SUM(yourCoumnName2) from yourTableName GROUP BY yourColumnName1 HAVING COUNT(yourCoumnName2) = COUNT(*);To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table SumDemo -> ( -> Id int, -> Amount int -> ); Query OK, 0 rows affected (0.58 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into SumDemo values(1, 200); Query OK, 1 row affected (0.22 ... Read More
