Question

Design JavaFX application with 7 labels and one textfield where user enters input inches. When user enters his choice and presses enter key to complete input, program outputs resulting yards, feet, and inches.

• Use class P5 that extends Application with start method in it, and class P5Pane that extends GridPane. The only instance variables for P5Pane class are inputInches where user enters input inches, and three labels: outYards, outFeet, and outInches where program displays result of conversion. Use the following names for instance variables:

                           private Label outYards, outFeet, outInches;

                           private TextField inputInches;

• All other variables should be local where needed.
• Title bar of the output window must have your first and last name and not mine at the end of the given title.
• Provide also UML with classes P5, P5Pane, Application, and GridPane. The boxes for Application and GridPane can only have top part filled, since they are Java classes. Relationships must be specified.

Working code implemented in Java and appropriate comments provided for better understanding:

Here I am attaching code for these files:

• P5.java
• P5Pane.java

public class P5 extends Application
{
public void start(Stage stage)
{
Scene scene = new Scene(new P5Pane(), 300, 150);
  
stage.setTitle("Converting inches to yards,feet,inches");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}

public class P5Pane extends GridPane
{
private Label outYards,outFeet,outInches;
private TextField inputInches;

public P5Pane()
{
Label inputLabel = new Label("Input Inches in Range 0 to 100000 :");
GridPane.setHalignment(inputLabel, HPos.RIGHT);

Label yardsLabel = new Label("Yards:");
GridPane.setHalignment(yardsLabel, HPos.RIGHT);

inputInches.setOnAction(this::calculate);

setAlignment(Pos.CENTER);
setHgap(20);
setVgap(10);
setStyle("-fx-background-color: limegreen");

add(inputLabel, 0, 0);

}

public void calculate(ActionEvent event)
{
int number = Integer.parseInt(inputInches.getText());
int yard = (int) (number/36);
int yard_rem = (int) (number%36);
int feet = (int) (yard_rem/12);
int feet_rem = (int) (yard_rem%12);
int inches = feet_rem;

outYards.setText(yard+"");
outFeet.setText(feet+"");
outInches.setText(inches+"");   
}
}

UML Diagram:
