Question

Write a program that displays a string “Welcome to Java” around the circle, as shown below. You need to display each character in the right location with appropriate rotation using a loop.

Directions

Create a class named Characters extends Application.

Create a new pane.

Create an object of Font class and define font features as bold, Times New Roman, regular and size of 35.

Create a string of “Welcome to Java”

Create a for loop to scan through each character of “Welcome to Java” string.

Inside the for loop, create an instance of Text on the given coordinates containing the given characters by use constructor of Text(double x, double y, java.lang.String text)

Use setFont( ) and setRotate( ) methods of Text class to define characters and their rotated positions

Add text instance to the pane by using getChildren().add() method

Create a scene with a specific size

Set title to “Characters around circle” and display the stage

The output should look like the screen below.

Provide appropriate Java comments

Explanation / Answer

package welcome;
import javafx.application.Application;
import javafx.geometry.Point2D;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class cirjava extends Application{
    @Override
    public void start(Stage primaryStage) {
        Pane pane = new Pane();
        String[] java = "Welcome to Java".split("");
        Font font = Font.font("Times New Roman", FontWeight.EXTRA_BOLD, 35);
  
  
  
        // x = a+r * cos t
        // y = b+r * sin t
        // where t is a parametric variable in the range 0 to 2,
        Point2D center = new Point2D(200, 200);
        double radius = 100;
        double angle = 0;
        double rotate = 90;
        for (int i = 0; i < java.length; i++, angle += 22, rotate += 22) {
            double x = center.getX() + radius * Math.cos(Math.toRadians(angle));
            double y = center.getY() + radius * Math.sin(Math.toRadians(angle));
            Text text = new Text(x, y,java[i]);
            text.setRotate(rotate);
            text.setFont(font);
            pane.getChildren().add(text);
        }
        Scene scene = new Scene(pane, 400, 400);
        primaryStage.setTitle("Welcome to Java");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
    public static void main(String[] args) {
        Application.launch(args);
    }
}
