In JavaFX, the text node is represented by the Javafx.scene.text.Text class. To insert/display text in JavaFx window you need to −Instantiate the Text class.Set the basic properties like position and text string, using the setter methods or, bypassing them as arguments to the constructor.Add the created node to the Group object.If the length of the lines in the text you have passed, longer than the width of the window part of the text will be chopped as shown below −As a solution you can wrap the text within the width of the window by setting the value to the property wrapping ...

Since the javafx.scene.text.Text class in JavaFX inherits the Shape class it inherits all its members. You can modify the stroke and color of the text node by setting values to the stroke, stroke width and fill properties inherited by the Text class.Stroke Width − The stroke width property specifies/defines the width of the boundary line of a shape. You can set value to the width of the boundary using the setWidth() method of the Shape class.Fill − The fill property specifies/defines the color with which the interior area of the shape is to be filled. You can fill a particular ... Read More
In JavaFX, the text node is represented by the javafx.scene.text.Text class. By default, the text created by JavaFX will be as follows −Setting the desired font to the text nodeYou can set the desired font to the text node in JavaFX using the setFont() method. This method accepts an object of the class javafx.scene.text.Font.The Font class represents the fonts in JavaFX, this class provides several variants of a method named font() as shown below −font(double size) font(String family) font(String family, double size) font(String family, FontPosture posture, double size) font(String family, FontWeight weight, double size) font(String family, FontWeight weight, FontPosture posture, ...

In JavaFX, the text node is represented by the javafx.scene.text.Text class. You can add text to a JavaFX window by instantiating this class.Following are the basic properties of the text node −X − This property represents x coordinate of the text. You can set value to this property using the setX() method.Y − This property represents y coordinate of the text. You can set value to this property using the setY() method.text − This property represents the text that is to be displayed on the JavaFX window. You can set value to this property using the setText() method.To insert/display text ... Read More
If the stroke used is a dashing pattern. the strokeDashOffset property specifies the offset into the dashing pattern. i.e. the dash phase defines the point in the dashing pattern that will correspond to the beginning of the stroke.Exampleimport javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Line; import javafx.scene.shape.Polygon; import javafx.stage.Stage; public class StrokeDashOffset extends Application { public void start(Stage stage) { Line shape1 = new Line(25.0, 50.0, 565.0, 50.0); shape1.setStroke(Color.BROWN); shape1.setStrokeWidth(10); shape1.getStrokeDashArray().addAll(80.0, 70.0, 60.0, 50.0, 40.0); shape1.setStrokeDashOffset(5); Polygon shape2 = ...

The smooth property specifies whether antialiasing hints are used or not. You can set the value to this property using the setSmooth() method of the javafx.scene.shape.Shape class.This method accepts a boolean value and if you pass true the edges of the shape will be smoothened.Exampleimport javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Polygon; import javafx.scene.shape.StrokeLineJoin; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.scene.text.Text; import javafx.stage.Stage; public class SmoothExample extends Application { public void start(Stage stage) { Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12); Text label2 = new Text("Smooth: true"); ...

This operation takes two or more shapes as inputs and returns the area occupied by them combined as shown below.The union() (static) method of the javafx.scene.shape.Shape class accepts two Shape objects and returns the result of the union operation of the given objects.Exampleimport javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.stage.Stage; import javafx.scene.shape.Circle; import javafx.scene.shape.Shape; public class JavaFXUnionExample extends Application { public void start(Stage stage) { //Drawing circle1 Circle circle1 = new Circle(); circle1.setCenterX(230.0f); circle1.setCenterY(100.0f); circle1.setRadius(75.0f); circle1.setFill(Color.DARKRED); ...

JShell is an interactive REPL tool to execute and evaluate simple Java programs like variable declarations, statements, expressions, and etc.When the JShell tool launched, the code has pre-loaded by default. To display this code, we just launch the command "/list -start". It is possible to ask JShell to load them automatically when it starts by using the command: "/set start [-retain] [Type]". The first option "-retain" tells JShell to record the desired [Type] startup for the next JShell sessions. If we don't specify it, the default startup can be launched when opening a new session /set start [-retain] -File /set start ... Read More
Java 9 supports to create Reactive Streams by introducing a few interfaces: Publisher, Subscriber, Subscription, and SubmissionPublisher class that implements the Publisher interface. Each interface can play a different role corresponding to the principles of Reactive Streams.We can use the Subscriber interface to subscribe to the data that is being published by a publisher. We need to implement the Subscriber interface and provide an implementation for the abstract methods.Flow.Subscriber interface methods:onComplete(): This method has been called when the Publisher object completes its role.onError(): This method has been called when something goes wrong in Publisher and is notified to the Subscriber.onNext(): This method has been called whenever ...

It occurs when Index is outside the bounds of the array.Let us see an example. We have declare an array with 5 elements and set the size as 5.int[] arr = new int[5]; arr[0] = 10; arr[1] = 20; arr[2] = 30; arr[3] = 40; arr[4] = 50;Now, we try to add the value of an element that extends the size of our array i.e.arr[5] = 60;Above, we are trying to add element at 6th position.Example Live Demousing System; using System.IO; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { ...
