To change the background and foreground colors of tab, use the following methods −JTabbedPane tabbedPane = new JTabbedPane(); tabbedPane.setBackground(Color.blue); tabbedPane.setForeground(Color.white);Above, we have used the Color class to set the colors for the background and foregroud colors −The following is an example to change the background and foreground colors of tab −package my; import javax.swing.*; import java.awt.*; import java.awt.event.KeyEvent; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Devices"); JTabbedPane tabbedPane = new JTabbedPane(); JPanel panel1, panel2, panel3, panel4, panel5; panel1 = new ...

Use the setHgap() method to set the horizontal gap between elements in a GridLayout. Let’s say we have a GridLaypout −GridLayout layout = new GridLayout(2, 4);Set the horizontal gap −layout.setHgap(25);The following is an example −Examplepackage my; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextArea; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Sections"); JPanel panel = new JPanel(); panel.setBackground(Color.blue); GridLayout layout = new GridLayout(2, 4); ...

For this, use MongoDB $substr. Let us first create a collection with documents −> dblimitTheNumberOfCharactersDemoinsertOne({"Title":"MongoDB is No SQL database"}); { "acknowledged" : true, "insertedId" : ObjectId("5cf23013b64a577be5a2bc0e") } > dblimitTheNumberOfCharactersDemoinsertOne({"Title":"MySQL is a relational database"}); { "acknowledged" : true, "insertedId" : ObjectId("5cf2302db64a577be5a2bc0f") } Following is the query to display all documents from a collection with the help of find() method −> dblimitTheNumberOfCharactersDemofind()pretty();This will produce the following document −{ "_id" : ObjectId("5cf23013b64a577be5a2bc0e"), "Title" : "MongoDB is No SQL database" } { "_id" : ObjectId("5cf2302db64a577be5a2bc0f"), "Title" : "MySQL is a relational database" }Following is the ...

focus()Javascript focus() methods helps to highlight a HTML form element. It sets the element as an active element in the current document. In current documentation, focus can be applied to only one single element. The focus can be applied either to a text, a button, etc. syntaxelement.focus(options);ExampleIn the following example, initially, the text "Tutorialspoint" is in an anchor tag 'a', which as an id called 'focus'. Later on, a function is declared in which the id is called using a DOM method and focus() method is applied on it to change the color of text "Tutorialspoint" to red. Here a button ... Read More
The HTML DOM Input URL autofocus property sets/returns whether Input URL is focused upon initial page load.SyntaxFollowing is the syntax −Returning boolean value - true/falseinputURLObject.autofocusSetting autofocus to booleanValueinputURLObject.autofocus = booleanValueBoolean ValuesHere, “booleanValue” can be the following −booleanValueDetailsTrueIt defines that input will be autofocused on page load.FalseIt is the default value and input is not autofocused.ExampleLet us see an example of Input URL autofocus property − Live Demo Input URL autofocus form { width:70%; margin: 0 auto; text-align: center; } * { padding: 2px; ...

Here we will see how to check whether a given input is integer string or a normal string. The integer string will hold all characters that are in range 0 – 9. The solution is very simple, we will simply go through each characters one by one, and check whether it is numeric or not. If it is numeric, then point to the next, otherwise return false value.Example#include using namespace std; bool isNumeric(string str) { for (int i = 0; i < str.length(); i++) if (isdigit(str[i]) == false) return false; //when one ...
