To set the JSlider vertical, use the VERTICAL constant while creating the slider. Let us create a new Slider −JSlider slider = new JSlider(JSlider.VERTICAL, 0, 100, 60);The other parameter values set above allows you to include the minimum, maximum and the initial value of the slider.The following is an example to set the slider vertical and move bottom-to-top −Examplepackage my; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Frame with Slider"); JSlider slider = new JSlider(JSlider.VERTICAL, 0, 100, 60); ...

To get last inserted document, use sort() along with limit(1).Let us first create a collection with documents −> db.getLastInsertedDocument.insertOne({"Name":"John"}); { "acknowledged" : true, "insertedId" : ObjectId("5cefb17eef71edecf6a1f6a8") } > db.getLastInsertedDocument.insertOne({"Name":"Chris"}); { "acknowledged" : true, "insertedId" : ObjectId("5cefb181ef71edecf6a1f6a9") } > db.getLastInsertedDocument.insertOne({"Name":"Robert"}); { "acknowledged" : true, "insertedId" : ObjectId("5cefb185ef71edecf6a1f6aa") }Display all documents from a collection with the help of find() method −> db.getLastInsertedDocument.find();Output{ "_id" : ObjectId("5cefb17eef71edecf6a1f6a8"), "Name" : "John" } { "_id" : ObjectId("5cefb181ef71edecf6a1f6a9"), "Name" : "Chris" } { "_id" : ObjectId("5cefb185ef71edecf6a1f6aa"), "Name" : "Robert" }Following is the query to get last inserted document −> db.getLastInsertedDocument.find({}).sort({_id:-1}).limit(1);Output{ "_id" ...

To convert time to seconds, use the TIME_TO_SEC() method. Let us first create a table −mysql> create table DemoTable -> ( -> ArrivalTime time -> ); Query OK, 0 rows affected (0.63 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('04:10:00'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('05:20:50'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('06:40:10'); Query OK, 1 row affected (0.18 sec)Display all records from the table using select statement −mysql> select *from DemoTable;Output+-------------+ | ArrivalTime | +-------------+ | 04:10:00 ...

Following is a Java program which prints a pyramid of numbers.Example Live Demopublic class PrintingPyramids { public static void main(String args[]){ int n,i,j,k=1; n = 5; for(i = 0; i
Here we will see how to get the area of a triangle formed by the x and y axis and another straight line. The diagram will be look like below. The equation of the straight line is −𝑎𝑥+𝑏𝑦+𝑐=0The line is cutting the x-axis at the point B, and cutting the y-axis at the point A. The intercept form will be like below −So the x-intercept is −𝑐∕𝑎 and y-intercept is −𝑐∕𝑏 . So the area of the triangle isExample Live Demo#include #include using namespace std; double areaTriangle(double a, double b, double c){ return fabs((c*c) / (2*a*b)); } main() { ... Read More
Python provides a very simple way of creating or publishing packages.Package management in Python is available through different tools−Pip- It remains one of the preferred choices because it virtually eliminates any manual installs and updates of software packages to operating systems. It manages full lists of packages and their corresponding version numbers, which fosters precise duplication of entire package groups in a distinct, separate environment.Python Package Index (PPI) is a public package repository of user-submitted packages that can be installed using pip .i.e. pip install package_name.Below is a step-by-step procedure on how to upload the package.Step 1: Have a package ...

To set default button for JFrame, use the setDefaultButton() method −JFrame frame = new JFrame(); frame.getRootPane().setDefaultButton(button);The following is an example to set default button for JFrame −Exampleimport java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyEvent; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo { public static void main(String args[]) { JButton button = new JButton("Demo Button!"); JFrame frame = new JFrame(); frame.setSize(500, 300); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getRootPane().setDefaultButton(button); button.setMnemonic(KeyEvent.VK_A); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { ...

You can use map() for this. Let us first create a collection with documents −> db.deleteDemo.insertOne({"Name":"John"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd550492cba06f46efe9f06") } > db.deleteDemo.insertOne({"Name":"Carol"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd5504d2cba06f46efe9f07") } > db.deleteDemo.insertOne({"Name":"Sam"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd550512cba06f46efe9f08") } > db.deleteDemo.insertOne({"Name":"David"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd5505d2cba06f46efe9f09") } > db.deleteDemo.insertOne({"Name":"Robert"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd550682cba06f46efe9f0a") } > db.deleteDemo.insertOne({"Name":"Chris"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd5506f2cba06f46efe9f0b") } > db.deleteDemo.insertOne({"Name":"Mike"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd550752cba06f46efe9f0c") } > db.deleteDemo.insertOne({"Name":"Bob"}); ...

To get the depth of root node in a JTree in Java, use the getDepth() method. Let’s say our root node is “node”, therefore, we will get the depth of root node like this −node.getDepth();The following is an example to get the depth of root node −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("Website"); DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Videos"); DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Tutorials"); DefaultMutableTreeNode ...
