This example demonstrate about How to create an Android notification without the icon in the status barStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details tocreate a new project.Step 2 − Add the following code to res/layout/activity_main.xml. Step 3 − Add the following code to res/layout/custom_notification_layout.xml. Step 4 − Add the following code to src/MainActivity.package app.tutorialspoint.com.notifyme ; import android.app.NotificationChannel ; import android.app.NotificationManager ; import android.os.Bundle ; import android.support.v4.app.NotificationCompat ; import android.support.v7.app.AppCompatActivity ; import android.view.View ; import android.widget.RemoteViews ; public class ...

Center a component in a JPanel with GridBagLayout. Let us first create a JFrame and JPanel inside it -JFrame frame = new JFrame("Demo Frame"); JPanel panel = new JPanel();Now, we will add our components −JLabel label = new JLabel("Demo Label (Centered)"); label.setForeground(Color.white); JCheckBox checkBox = new JCheckBox("Checkbox (Centered)");Set the layout −panel.setLayout(new GridBagLayout());The following is an example to center a label in a panel with GridBagLayout −Examplepackage my; import java.awt.Color; import java.awt.GridBagLayout; import javax.swing.JCheckBox; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Demo ...

To check whether a node is a root node or not, use the isRoot() method. This returns a boolean value. TRUE if the node is a root node, else FALSE is returned. For example, TRUE is returned since the following node is a root node −node.isRoot()Another example, FALSE is returned since the following node isn’t a root node −node2.isRoot()The following is an example to check whether a node is a root node or not −Examplepackage my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.tree.DefaultMutableTreeNode; public class SwingDemo { public static void main(String[] args) throws Exception { JFrame frame ...

You can use $where operator along with some script.Let us first create a collection with documents −> dbsameValueMultipleTimesDemoinsertOne( { "ListOfPrice":[ {"Price": 110}, {"Price":130}, {"Price": 145} ] } ); { "acknowledged" : true, "insertedId" : ObjectId("5cefc4e6ef71edecf6a1f6b9") } > dbsameValueMultipleTimesDemoinsertOne( { "ListOfPrice":[ {"Price": 110}, {"Price":178}, {"Price": 110} ] } ); { "acknowledged" : true, "insertedId" : ObjectId("5cefc4e7ef71edecf6a1f6ba") }Following ...

For this, you can use concat() function from MySQL. Let us first create a table −mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(20), -> Subject varchar(100) -> ); Query OK, 0 rows affected (17.73 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(Name, Subject) values('John', 'MySQL'); Query OK, 1 row affected (1.19 sec) mysql> insert into DemoTable(Name, Subject) values('Chris', 'SQL Server'); Query OK, 1 row affected (0.88 sec) mysql> insert into DemoTable(Name, Subject) values('Robert', 'MongoDB'); Query OK, 1 row affected ...

exec()The exec() method is a regex method. It searches a string for a specified pattern and, unlike test() regex method, returns the found text as an object. If there are no matches it will give null as an output. Let's discuss it in detail.Example-1In the following example, a variable pattern "est" is checked through the exec() method. The exec() regex method, after scrutinizing the given pattern throughout the text, returned the pattern as an object.Live Demo var obj = /est/.exec("Tutorix is the best e-learning platform"); document.write( "The object is ...

In this section we will see what are the usage of array::fill() and the array::swap() in C++ STL.The array::fill() function is used to fill the array with some specified value. Let us see one example to get the idea.Example Live Demo#include #include using namespace std; main() { array arr = {00, 11, 22, 33, 44, 55, 66, 77, 88, 99}; cout
The zipapp module has been introduced in Python's standard library since ver 3.5. This module is used to manage the creation of zip files containing Python code, which can be executed directly by the Python interpreter. The module provides both a Command-Line Interface and a programming interface.To use zipapp module programmatically, we should have a module in which main function is present. The executable archive is built by following command −python -m zipapp myapp -m "example:main"Here, the current path should have a folder called myapp. In this folder, there should be example.py which must have main() function.Create myapp folder and ...

Python compliles the .py files and save it as .pyc fileThe .pyc contain the compiled bytecode of Python source files, A .pyc is not created for your main program file that you execute (only for imported modules).The .pyc file contains encoded python bytecode.If We Want to import module.The Module calculate Addition of Two NumbersExample Live Demodef recursive_sum(n): """Function to return the sum of recursive numbers""" if n
