You can use aggregate framework for this. Let us first create a collection with documents −>db.aggregationOperatorDemo.insertOne({"FirstValue":392883,"SecondValue":10000000000}); { "acknowledged" : true, "insertedId" : ObjectId("5cd541452cba06f46efe9f01") }Following is the query to display all documents from a collection with the help of find() method −> db.aggregationOperatorDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd541452cba06f46efe9f01"), "FirstValue" : 392883, "SecondValue" : 10000000000 }Following is the query to use divide aggregation operator −> db.aggregationOperatorDemo.aggregate([ ... { "$project": { "Value": { "$divide": ["$FirstValue", "$SecondValue"] } } } ... ]);This will produce the following output −{ "_id" : ObjectId("5cd541452cba06f46efe9f01"), "Value" : 0.0000392883 }
To find a node in a JTree component, use the getNextMatch() method. Here, wer are trying to find a node that begins with character “A”. The search begins from the node set below with begnRow variable −int begnRow = 0; String prefix = "A"; TreePath treePath = tree.getNextMatch(prefix, begnRow, Position.Bias.Forward);We have displayed the resultant node in the Console −System.out.println("Node = "+treePath);The following is an example to find a node in a JTree Component with Java −package my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.text.Position; import javax.swing.tree.DefaultMutableTreeNode; import javax.swing.tree.TreePath; public class SwingDemo { public static void main(String[] args) throws Exception { ...

Let us see how to set the raised SoftBevelBorder −Border raisedBorder = new SoftBevelBorder( SoftBevelBorder.RAISED, Color.GREEN, Color.GREEN.darker(), Color.MAGENTA, Color.magenta.brighter());Let us see how to set the lowered SoftBevelBorder −Border loweredBorder = new SoftBevelBorder( SoftBevelBorder.LOWERED, Color.ORANGE, Color.YELLOW.darker(), Color.BLUE, Color.yellow.brighter());The following is an example to set raised and lowered SoftBevelBorder for components in Java −Examplepackage my; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Container; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.border.Border; import javax.swing.border.SoftBevelBorder; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Border raisedBorder = ...

Let us first create a collection with documents −> db.findDataDemo.insertOne( { "_id": new ObjectId(), "CustomerName":"John", "CustomerDetails" : { "CountryName" : [ "AUS" ], "isMarried" : [ false ] } } ); { "acknowledged" : true, "insertedId" : ObjectId("5cefa5eeef71edecf6a1f6a5") } > db.findDataDemo.insertOne( { "_id": new ObjectId(), "CustomerName":"Carol", ...

GeneratorsJavaScript supports Generator functions and Generator Objects. A generator function is the same as a normal function, but whenever it needs to generate a value it uses the 'yield' keyword rather than 'return'. The 'yield' keyword halts the function execution and sends a value back to the caller. It has an ability that it can resume the functionality from where it is left off. syntaxfunction* generator(){ yeild 1; yeild 2; }ExampleIn the following example, using a generator function, natural numbers 10, 9 and 8 were printed. Instead of printing each number individually we can run ... Read More
Following is the syntax −select table_name, create_time from information_schema.TABLES where table_schema = 'yourDataBaseName' order by CREATE_TIME desc limit 1;Let us create the first table (Time: 2019-06-10 16:40:51) −mysql> create table DemoTable1 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(100), -> StudentAge int -> ); Query OK, 0 rows affected (0.59 sec)We will now create the second table, let’s say after 5 minutes −mysql> create table DemoTable2 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(100), -> StudentAge int -> ); Query ...

To find the angles of a triangle we can use sin/cosine rules according to cosine rule −cos A = (b^2 + c^2 - a^2)/2bcwhere A, B , C are the vertices and a, b, c are the sides of the given triangle then, angles of the triangle when the sides a, b, c given are −angleAtA = acos((b^2 + c^2 - a^2)/(2bc)) angleAtB = acos((a^2 + c^2 - b^2)/(2ac)) angleAtC = acos((a^2 + b^2 - c^2)/(2ab))
In this section, we’ll try to automate the movements of mouse and keyboard using pyautogui module in python.Pyautogui is a library that allows you to control the mouse and keyboard to do various things.It is a cross-platform GUI automation Python module for human beings.As it is a third party library, we need to install it.pip install pyautoguiMouseBelow is program to automate the movement of your mouse. On running your programme, you can see the mouse movement with every command. I run below command on CLI so as to capture the mouse movement. You can try with others different values too.Example>>> ... Read More
Use the setMinimumSize() method to set the minimum size limit for a JFrame −JFrame frame = new JFrame(); frame.setMinimumSize(new Dimension(500, 300));The following is an example to set minimum size limit for a JFrame −Exampleimport java.awt.Color; import java.awt.Dimension; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame(); JButton button = new JButton("Close!"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setContentPane(button); button.addActionListener(e -> { frame.dispose(); }); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setMinimumSize(new Dimension(500, ...
