How can we implement Flow API using Publisher-Subscriber in Java 9?
Flow API (java.util.concurrent.Flow) has introduced in Java 9. It helps to understand different ways in which the Publisher and Subscriber interfaces interact to perform desired operations.Flow API consists of Publisher, Subscriber, Subscription, and Processor interfaces, which can be based on reactive stream specification.In the below example, we can implement Flow API by using Publisher-Subscriber interfaces.Exampleimport java.util.concurrent.Flow.Publisher; import java.util.concurrent.Flow.Subscriber; import java.util.concurrent.Flow.Subscription; public class FlowAPITest { public static void main(String args[]) { Publisher publisherSync = new Publisher() { // Create publisher @Override public void subscribe(Subscriber
Read MoreWhat is text origin in JavaFX?
In addition to the local coordinate system for positioning its nodes, JavaFX provides an additional coordinate system for the text node.The textOrigin property specifies the origin of the coordinates of the text node in the parent coordinate system. You can set values to this property using the setTextOrigin() method. This method accepts one of the constants of the enum named VPos. This enum contains 4 constants namely: BASELINE, BOTTOM, CENTER and, TOP.Exampleimport java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import java.util.Scanner; import javafx.application.Application; import javafx.geometry.VPos; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.stage.Stage; import javafx.scene.text.Text; public class TextOriginExample extends Application { ...
Read MoreHow to strike through and underline text in JavaFX?
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.The strikethrough property of the javafx.scene.text.Text class determines whether each line of the text should have a straight line passing through the middle of it. You can set the value to this property using the setStrikeThrough() method. It accepts a boolean value. You can strike though the text (node) by ...
Read MoreHow to adjust the line spacing in the text node in JavaFX?
The line spacing property of the javafx.scene.text.The text class specifies the line spacing between the lines of the text (node) vertically.You can set the value to this property using the setLineSpacing() method. This method accepts a boolean value as a parameter and sets the specified space between the lines (vertically).Exampleimport java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import java.util.Scanner; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.stage.Stage; import javafx.scene.text.Text; import javafx.scene.text.TextAlignment; public class TextSpacing extends Application { public void start(Stage stage) throws FileNotFoundException { //Reading the contents of a text file. InputStream inputStream ...
Read MoreHow to adjust the alignments of the text in JavaFX?
You can set a fixed width for the text in user space by setting the value to the wrappingWidth property. Once you do so, given width is considered as the boundary of the text in user coordinates and, the text is arranged width in the given width.If you haven’t given any value for this property, by default, the length longest line in the text is considered as the width of the bounding box.Text alignment is the arrangement of the text horizontally within the bounding box. You can adjust the alignment of the text using the setTextAlignment() method. This method accepts ...
Read MoreHow to wrap the text within the width of the window in JavaFX?
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 ...
Read MoreHow to add stroke and color to text in JavaFX?
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 MoreExplain the stroke Dash Offset property of 2D shapes in JavaFX
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 = ...
Read MoreExplain the smooth property of 2D shapes in JavaFX
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"); ...
Read MoreExplain the Union operation on 2D shapes in JavaFX
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); ...
