The sorted() method in Java IntStream class is used to return a stream consisting of the elements of this stream in sorted order.The syntax is as followsIntStream sorted()The sorted() method returns the new stream. To work with the IntStream class, you need to import the following packageimport java.util.stream.IntStream;Create an IntStream and add some elementsIntStream intStream = IntStream.of(30, 50, 70, 120, 150, 200, 250, 300);Now, to sort the above stream elements, use the sorted() methodintStream.sorted() The following is an example to implement IntStream sorted() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo { public static void main(String[] args) { ...

The subList() method returns a part of this list between the specified fromIndex, inclusive, and toIndex, exclusive. Get a sublist using the method by setting the range as the two parameters.The syntax is as follows −public List subList(int fromIndex, int toIndex)Here, the parameter fromIndex is the low endpoint (inclusive) of the subList, whereas toIndex is the high endpoint (exclusive) of the subListTo work with the AbstractSequentialList class in Java, you need to import the following package −import java.util.AbstractSequentialList;The following is an example to implement AbstractSequentialList subList() method in Java −Example Live Demoimport java.util.LinkedList; import java.util.AbstractSequentialList; public class Demo { ...

This is a C++ program return a local array from a function.AlgorithmBegin We can use dynamically allocated array to return a local array from function Array(). Print the elements of the array. EndExample Code Live Demo#include using namespace std; int* Array() { int* a = new int[100]; a[0] = 7; a[1] = 6; a[2] = 4; a[3] = 5; return a; } int main() { int* p = Array(); cout
The SELECT INTO equivalent is CREATE TABLE AS SELECT statement. The syntax is as follows −CREATE TABLE yourNewTableName AS SELECT *FROM yourTableName;To understand the above concept, let us create a table. The query to create a table is as follows −mysql> create table selectIntoEquivalentDemo -> ( -> ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> ClientName varchar(20), -> ClientAge int -> ); Query OK, 0 rows affected (0.71 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into selectIntoEquivalentDemo(ClientName, ClientAge) values('Larry', 34); Query OK, 1 row affected (0.13 ... Read More
For many people, image processing may seem like a scary and daunting task but it is not as hard as many people thought it is. In this tutorial we’ll be doing basic color detection in openCv with python.How does color work on a computer?We represent colors on a computers by color-space or color models which basically describes range of colors as tuples of numbers.Instead of going for each color, we’ll discuss most common color-space we use .i.e. RGB(Red, Green, Blue) and HSV (Hue, Saturation, Value).RGB basically describes color as a tuple of three components. Each component can take a value ... Read More
This example demonstrate about How to use GridLayoutManager in RecyclerViewStep 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, we have taken recycerview.Step 3 − Add the following code to src/MainActivity.java import android.annotation.TargetApi; import android.os.Build; import android.os.Bundle; import android.support.v4.content.ContextCompat; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.DefaultItemAnimator; import android.support.v7.widget.DividerItemDecoration; import android.support.v7.widget.GridLayoutManager; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.support.v7.widget.Toolbar; import android.widget.TextView; import android.widget.Toast; import java.util.ArrayList; public ...

With this, get the nanoseconds in days, hours and minutes. At first, set the Duration:Duration d1 = Duration.ofDays(5); Duration d2 = Duration.ofHours(20); Duration d3 = Duration.ofMinutes(15);Convert the above Duration to nanoseconds:System.out.println("Nanoseconds in 5 days = "+d1.toNanos()); System.out.println("Nanoseconds in 20 hours = "+d2.toNanos()); System.out.println("Nanoseconds in 15 minutes = "+d3.toNanos());Exampleimport java.time.Duration; public class Demo { public static void main(String[] args) { Duration d1 = Duration.ofDays(5); Duration d2 = Duration.ofHours(20); Duration d3 = Duration.ofMinutes(15); System.out.println("Nanoseconds in 5 days = "+d1.toNanos()); System.out.println("Nanoseconds in 20 hours = "+d2.toNanos()); ...

To set a flag, you can set the type as tinyint(1) type. Following is the syntax −yourColumnName tinyint(1) DEFAULT 1;Let us first create a table −mysql> create table DemoTable ( ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY, ClientName varchar(20), isMarried tinyint(1) DEFAULT 1 ); Query OK, 0 rows affected (0.64 sec)Insert some records in the table using insert command −mysql> INSERT INTO DemoTable(ClientName, isMarried) values('Larry', 0); Query OK, 1 row affected (0.16 sec) mysql> INSERT INTO DemoTable(ClientName) values('David'); Query OK, 1 row affected (0.12 sec) mysql> INSERT INTO DemoTable(ClientName, isMarried) values('Mike', 1); Query OK, 1 row affected (0.19 ...

The buffer can be compacted using the compact() method in the class java.nio.IntBuffer. This method does not require a parameter and it returns the new compacted IntBuffer with the same content as the original buffer. 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(3); buffer.put(7); ...

The random object can be reseeded using the setSeed() method in the class java.security.SecureRandom. This method requires a single parameter i.e. the required seed byte array and it returns the reseeded random 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"); String str = "Apple"; byte[] arrB = str.getBytes(); sRandom.setSeed(arrB); byte[] arrSeed = sRandom.getSeed(5); ...
