To set the alignment of the label content along the Y axis, use the setVerticalAlignment() method. Let us first set a label component. We have set the label background color as well so that we can check the alignment of the label’s content properly −JLabel label = new JLabel("Product Name "); label.setPreferredSize(new Dimension(190, 100)); label.setOpaque(true); label.setBackground(Color.ORANGE);Now, we will align the label content along the Y axis −label.setVerticalAlignment(JLabel.CENTER);The following is an example to set the alignment of the JLabel content along the Y axis −Examplepackage my; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextArea; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Our Frame ...

You can use $in operator. Let us first create a collection with documents −> db.tagCountDemo.insertOne({"ListOfNames":["John", "Sam", "Carol"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b387924bb85b3f48944") } > db.tagCountDemo.insertOne({"ListOfNames":["Bob", "David", "John"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b4b7924bb85b3f48945") } > db.tagCountDemo.insertOne({"ListOfNames":["Mike", "Robert", "Chris"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b5d7924bb85b3f48946") } > db.tagCountDemo.insertOne({"ListOfNames":["James", "Carol", "Jace"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b717924bb85b3f48947") }Following is the query to display all documents from a collection with the help of find() method −> db.tagCountDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd64b387924bb85b3f48944"), "ListOfNames" : ...

In this section we will see the isnormal() function in C++. This function is present in the cmath library. This function is used to check whether a number is normal or not. The numbers that are considered as non-normal are zeros, infinity or NAN.This function takes float, double or long double values as argument. Returns 1 if the number is normal, otherwise returns 0.Example Live Demo#include #include using namespace std; int main() { cout
Enumeration (enum) in Java is a datatype which stores a set of constant values (Strings in general). You can use enumerations to store fixed values such as days in a week, months in a year etc.enum Days { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY }Custom values to the constantsInstead of declaring just string constants in an enum, you can also have values to these constants as −enum Vehicles { ACTIVA125(80000), ACTIVA5G(70000), ACCESS125(75000), VESPA(90000), TVSJUPITER(75000); }Whenever, you need to assign custom values to the constants of an enum −To hold the value of each ...

Here, the task is to print those number in an array having 1, 2 and 3 as digits in their numbers and if their is no such number than the output must be -1Input : arr[] = {320, 123, 124, 125, 14532, 126, 340, 123400, 100032, 13, 32, 3123, 1100} Output : 123 3123 14532 100032 123400 Since the array have values with digits 1, 2 and 3 it wouldn’t return -1 and print 5 values that Contain 1, 2 and 3 in their respective numbers.AlgorithmSTART Step 1 -> Declare array with elements of int type as arr Step ...

You can use every() in MongoDB for this. Let us create a collection with documents −> db.arrayConditionDemo.insertOne({"Name":"John", "Marks":[40, 43, 45]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd06de8cc557214c0e1a") } > db.arrayConditionDemo.insertOne({"Name":"Mike", "Marks":[45]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd17de8cc557214c0e1b") } > db.arrayConditionDemo.insertOne({"Name":"Chris", "Marks":[43, 45, 59, 69, 78, 89]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd3cde8cc557214c0e1c") }Display all documents from a collection with the help of find() method. The query is as follows −> db.arrayConditionDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cbdbd06de8cc557214c0e1a"), "Name" : "John", "Marks" : [ ... Read More
You can use regular expression along with $not operator to ignore a specific character and display rest of them. Let us first create a collection with documents −> db.regexDemo.insertOne({"CustomerId":"Customer#1234", "CustomerName":"Chris"}); { "acknowledged" : true, "insertedId" : ObjectId("5cc7428f8f9e6ff3eb0ce436") } > db.regexDemo.insertOne({"CustomerId":"Customer5678", "CustomerName":"Robert"}); { "acknowledged" : true, "insertedId" : ObjectId("5cc7429e8f9e6ff3eb0ce437") } > db.regexDemo.insertOne({"CustomerId":"Customer#777", "CustomerName":"Carol"}); { "acknowledged" : true, "insertedId" : ObjectId("5cc742ae8f9e6ff3eb0ce438") } > db.regexDemo.insertOne({"CustomerId":"Customer777", "CustomerName":"David"}); { "acknowledged" : true, "insertedId" : ObjectId("5cc742bc8f9e6ff3eb0ce439") }Following is the query to display all documents from a collection with the help of find() method −> db.regexDemo.find().pretty();This will produce the ...

Let’s say we want the parent of a node, then use the getParent() method -node3.getFirstChild()You can also get the parent of child node. Here, “nine” is the child node −nine.getParent()The output is as follows displaying this node’s parent on Console −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 = new JFrame("Demo"); DefaultMutableTreeNode node = new DefaultMutableTreeNode("Products"); DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Clothing (Product1 - P66778)"); DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Accessories (Product2 - P66779)"); ...
