Expert Solution & Answer
Chapter 13, Problem 12AW
Explanation of Solution
TextArea:
- The “TextArea” is a multiline “TextField” that can take many lines of input.
- It is present in the “javafx.scene.control” package.
- The “TextArea” class contains two constructors such as no-argument constructor and argument constructor.
- The “no-argumnet constructor” is used to create an empty “TextArea”.
- The “argument constructor” accepts a “String” argument in “TextArea” field.
- The “TextArea” control performs a word wrapping.
- The line breaks always occur between words, not in the middle of a word.
- User can enable the text wrapping by using “TextArea” class “setWrapText()” method.
- This method takes a “boolean” argument.
- If the user passes the argument is “true”, then text wrapping is enabled.
- Otherwise, the text wrapping is disabled.
Example:
The example for “no-argument constructor” and “argument constructor” is shown below:
//for no-arg constructor
TextArea sampleArea = new TextArea();
- Above statement creates a TextArea with no arguments.
//for argument constructor
TextArea sampleArea = new TextArea("This is an example TextArea");
- Above statement creates a TextArea with arguments.
The example for creating an empty “TextArea” with the height, width and line wrapping is shown below:
//create the empty TextArea control
TextArea exampleText = new TextArea();
//set a width of 30 columns to empty "TextArea"
exampleText...

Draw a wall with "irregular wavy color bands". Hint: you can use curveVertex and random functions in p5js library.
Note: You should use loops to draw the lines, not manually write 50-100 line functions
How would i answer this question using the code below:
function setup() {
createCanvas(350, 350);
}
function draw() {
background(200);
background('blue');
noFill();
//this will run a loop form -20 to fill the whole canvas
for(let y=-20; y<300; y+=4){
beginShape();
Stroke("yelllow");
//now to link point to point in curve
//y is height
curveVertex(0, y+0);
curveVertex(0, y+20);
curveVertex(50, y+0);
curveVertex(100, y+20);
curveVertex(150, y+0);
curveVertex(200, y+20);
curveVertex(250, y+0);
curveVertex(300, y+20);
curveVertex(350, y+0);
curveVertex(400, y+0);
endShape();
}

Create a vector x which ranges in values from -180 to 180 in steps of 10. Then let y = x. These values are in degrees. Find a variable z = cosd(x)’*sind(y); Use surf to plot the surface plot, and label using commands xlabel, ylabel, and zlabel. Add a title.
You may use the following code segment:
// Create lightsPane Pane lightsPane = new Pane();Circle redCircle = new Circle(100, 60, 20);Circle yellowCircle = new Circle(100, 110, 20);Circle greenCircle = new Circle(100, 160, 20);redCircle.setStroke(Color.BLACK);redCircle.setFill(Color.WHITE);yellowCircle.setStroke(Color.BLACK);yellowCircle.setFill(Color.WHITE);greenCircle.setStroke(Color.BLACK);greenCircle.setFill(Color.WHITE);Rectangle rectangle = new Rectangle(65, 25, 70, 170);rectangle.setStroke(Color.BLACK);rectangle.setFill(Color.WHITE);lightsPane.getChildren().addAll(rectangle, redCircle, yellowCircle, greenCircle);
