The setAtX() method is used to set a new value in the Decade Tuple. Here, X is the index wherein you want to set the value. For example, setAt5() sets the value at index 5. The value to be included is to be set as the value in the parameter, likesetAt5(“Katie”);Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following packageimport org.javatuples.Decade;Note: Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path ... Read More
The Period can be obtained with the given number of days, months and years using the of() method in the Period class in Java. This method requires a 3 parameters i.e. the number of days, the number of months and the number of years. Also, it returns the Period object with the given number of days, months and years.A program that demonstrates this is given as followsExample Live Demoimport java.time.Period; public class Demo { public static void main(String[] args) { int days = 20; int months = 11; int years = ...

Steganography is a technique of hiding information behind the scene. It’s is not like cryptography which focuses on encrypting data(through different algorithms like SHA1, MD5 etc), steganography focuses more on hiding the data (data can be a file, image, message or video) within another file, image, message or video to avoid any attraction.So in this we’ll try to create a simple python program that hides the information behind the image without noticiable changes in the looks of the image. There are two main parts of the program – first is a decoding function that can extract secret information from an ... Read More
The insertRow() method of the ResultSet interface inserts a new row into the ResultSet object as well as the table.//Deleting a column from the ResultSet object rs.insertRow();Assume we have a table named cricketers_data with 6 records as shown below:+----+------------+------------+---------------+----------------+-------------+ | ID | First_Name | Last_Name | Year_Of_Birth | Place_Of_Birth | Country | +----+------------+------------+---------------+----------------+-------------+ | 1 | Shikhar | Dhawan | 1981-12-05 | Delhi | India | | 2 | Jonathan | Trott | 1981-04-22 | CapeTown | SouthAfrica | | ...

Capped collections are fixed-size collections that support high-throughput operations that insert and retrieve documents based on insertion order. In order to set max on mongo capped collection, use the following syntaxdb.createCollection("yourCollectionName", {capped:true, size:yourSizeValue, max:yourMaxValue});Let us implement the above syntax in order to set max on mongo capped collection. Following is the query> db.createCollection("setMaxDemo", {capped:true, size:948575757, max:2000});This will produce the following output{ "ok" : 1 }You can now get all information about the above collection> db.setMaxDemo.stats();This will produce the following output{ "ns" : "test.setMaxDemo", "size" : 0, "count" : 0, "storageSize" : 4096, "capped" : true, ...

First, create an Integer array −Integer[] strArray = new Integer[] { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };Now, convert it into a List −Listlist = Arrays.asList(strArray);Use Collections to shuffle as shown below −Collections.shuffle(list);Example Live Demoimport java.util.Arrays; import java.util.Collections; import java.util.List; public class Demo { public static void main(String args[]) { Integer[] strArray = new Integer[] { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 }; Listlist = Arrays.asList(strArray); System.out.println("List = "+list); Collections.shuffle(list); System.out.println("Shuffled List = "+list); } }OutputList = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] Shuffled List = [100, 90, 40, 70, 20, 10, 80, 30, 60, 50]
You need to use GROUP BY with COUNT(*) for this to group the values and display the count eliminating multiple values. Let us first create a table:mysql> create table DemoTable (Value int); Query OK, 0 rows affected (0.55 sec)Following is the query to insert some records in the table using insert command:mysql> insert into DemoTable values(10); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values(20); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(10); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(30); Query OK, 1 row affected (0.14 sec) mysql> ...

The PriorityBlockingQueue Class in Java has a blocking queue that has unbounded functionality and is based on the class PriorityQueue with the same ordering rules. The PriorityBlockingQueue Class is a part of the Java Collection Framework.A program that demonstrates this is given as follows −Example Live Demoimport java.util.concurrent.PriorityBlockingQueue; public class Demo { public static void main(String[] args) { PriorityBlockingQueue pbQueue = new PriorityBlockingQueue(); pbQueue.add("James"); pbQueue.add("May"); pbQueue.add("John"); pbQueue.add("Sara"); pbQueue.add("Anne"); System.out.println("The elements in PriorityBlockingQueue are: " + pbQueue); } }The ...

In this program we will see how to divide 16-bit number by an 8-bit number.Problem StatementWrite 8086 Assembly language program to divide 16-bit number stored in memory location offset 501. Divide it with 8-bit number stored in 500H. Also store result at memory offset 600.Discussiont8086 has DIV instruction to perform division. Take the 8-bit number into BL, and 16-bit number into AX. Now divide AX by BL. The result will be stored at AX.We are taking two numbers 24CF / 2D = D1InputAddressData……5002D501CF50224…… Flow Diagram Program OutputAddressData……600D1……
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 time() with local time in Android sqliteStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required ...
