To add components with a relative Y position, use the GridBagConstraints.RELATIVE constant. Set this to gridy field −GridBagConstraints constraints = new GridBagConstraints(); constraints.gridy = GridBagConstraints.RELATIVE;The following is an example to add components with a relative Y position in Java −Examplepackage my; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); panel.setLayout(new GridBagLayout()); GridBagConstraints constraints = new GridBagConstraints(); constraints.gridx = ...

To get MySQL LIKE statement, use the REGEX in MongoDB. Let us first create a collection with documents −> db.likeInMongoDBDemo.insertOne({"Name" : "Sam"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6922857806ebf1256f123") } > db.likeInMongoDBDemo.insertOne({"Name" : "John" }); { "acknowledged" : true, "insertedId" : ObjectId("5cd6923157806ebf1256f124") } > db.likeInMongoDBDemo.insertOne({"Name" : "Scott"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6924557806ebf1256f125") } > db.likeInMongoDBDemo.insertOne({"Name" : "Sean"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6924f57806ebf1256f126") } > db.likeInMongoDBDemo.insertOne({"Name" : "Samuel"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6925857806ebf1256f127") }Following is the query to display all documents from a collection with ...

The HTML DOM Anchor protocol property is used to set or return the protocol of a link in the href attribute.Following is the syntax to set the protocol property −anchorObj.protocol = protocol_urlAbove, protocol_url is the protocol of the URL. The values can be http, https, ftp, etc.Following is the syntax to return the protocol property −anchorObj.protocolLet us now see an example to implement the DOM Anchor protocol property −Example Live Demo Demo Heading Link = Services Display pathname Display hreflang Display port Display protocol function display1() { var ...

We know that C and C++ are very much similar in different aspects. The C++ has additional object oriented feature in it, but most of the C programs can also be correct in C++. Here we will see one program related to function call, that can be run when it is written in C, but will not work in C++.Example Live Demo#include void myFunction() { printf("Function called"); } int main() { myFunction(); myFunction(2); }OutputFunction called Function calledThis program will run in C and generates output, but when we want to compile in C++, it will return an error ...

Yes, Mongo shell treats numbers as float by default. To work it as int or any other type, you need to mention explicitly. You can use NumberInt() for this. The syntax is as follows −var anyVariableName= [NumberInt("yourValue1"), NumberInt("yourValue2"), .....N];Let us implement the above syntax in order to treat numbers as integer only (not float) −> var integerArrayDemo = [NumberInt("50"), NumberInt("60"), NumberInt("70"), NumberInt("90"), NumberInt("40")];Following is the query to display the array value −> printjson(integerArrayDemo);This will produce the following output −[ NumberInt(50), NumberInt(60), NumberInt(70), NumberInt(90), NumberInt(40) ]To display the array value, you can use print() −> ...
