It is very important to know how to create a circular progress bar for iOS developers, almost every application have this.This is mainly used in showing the downloading status, loading status or any other progress related thing.Creating Circular Progress bar may become very tedious for new programmers and they might struggle working with it.There are multiple way one can create circular progress bar. In this post we will be seeing one of the simplest and easiest way to create circular progress bar.So let’s get startedStep 1 − Open Xcode, Single View Application, name it CircularProgress.So we will be creating an ...

To add components with relative X and Y coordinates, you need to set both the gridx and gridy components −GridBagConstraints constraints = new GridBagConstraints(); constraints.gridy = GridBagConstraints.RELATIVE; constraints.gridx = GridBagConstraints.RELATIVE;The following is an example to add components with relative X and Y Coordinates −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(); ...

Yes, to display a database in the list, first create a database and add collection(s), else it won’t be visible in the list. After that, use the SHOW dbs command to display the database name in the list of databases.Following is the query to create a database −> use webcustomertracker; switched to db webcustomertrackerLet us first create a collection with documents −> db.first_Collection.insert({"Name":"Chris"}); WriteResult({ "nInserted" : 1 })Following is the query to display all documents from a collection with the help of find() method −> db.first_Collection.find();This will produce the following output −{ "_id" : ObjectId("5ce2760836e8b255a5eee94a"), "Name" : "Chris" }Following is ...

Difference between for...in and for...of loopsBoth the loops iterate over something. The main difference between them is in what they iterate over.1) for...in loopThis loop iterates over enumerable properties of an object in an arbitrary order. It cares only about properties but not values.In the following example by using for...in loop the properties of the array are iterated. Since it is an array, Index is an important property so index of each and every element will be iterated and displayed in the output. In addition to indexes some inherited properties such as "inherProp2", "inherProp1" are also displayed.Example-1Live Demo ... Read More
For this, use BETWEEN operator in MySQL. Let us first create a table −mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Start int, -> End int -> ); Query OK, 0 rows affected (0.91 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(Start, End) values(100, 200); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable(Start, End) values(400, 500); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable(Start, End) values(210, 350); Query OK, 1 row affected (0.11 sec)Display all ...

In this section, we will see how we can get the sum of all odd prime factors of a number in an efficient way. There is a number say n = 1092, we have to get all factor of this. The prime factors of 1092 are 2, 2, 3, 7, 13. The sum of all odd factors is 3+7+13 = 23. To solve this problem, we have to follow this rule −When the number is divisible by 2, ignore that factor, and divide the number by 2 repeatedly.Now the number must be odd. Now starting from 3 to square root ... Read More
To use the sizeof(), we can take the value using a variable x, using &x, it will print the address of it. Now if we increase the value of &x then it may increase in different way. If only one byte is increased, that means it is character, if the increased value is 4, then it is int or float and so on. So by taking the difference between &x + 1 and &x, we can get the size of x.Here we will use macro as the datatype is not defined in the function. And one more thing, we are ... Read More
Use aggregate function SUM() along with OVER. Let us first create a table −mysql> create table DemoTable ( CustomerId int NOT NULL AUTO_INCREMENT PRIMARY KEY, CustomerValue int ); Query OK, 0 rows affected (0.64 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(CustomerValue) values(10); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable(CustomerValue) values(20); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable(CustomerValue) values(30); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable(CustomerValue) values(40); Query OK, 1 row affected (0.14 sec)Display all records ...

To style code in a TextPane component use the setText() for text and work with HTML tags. For code, use the tag. Also, do not forget to set the content type to “text/html” −JTextPane pane = new JTextPane(); pane.setContentType("text/html");If you won’t set the content type, then the output will display all these HTML tags inside the JTextPane. Now, set the code inside −pane.setText(" #include ; using namespace std; main() {cout
