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();
}
}

Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3. Given student…
Suppose you are using a jQuery animation to make an element change color when the user clicks on it, and you also want to execute a function as soon as the animation finishes running. How can you do this?
a.
Pass the function in as the first argument to theanimate()method called on the element.
b.
Use anif elseblock with thehasClass()method to determine when to call the function.
c.
Pass the function in as the final argument to theanimate()method called on the element.
d.
You cannot accomplish this using jQuery commands.

Create a java version of this game with the following requirements. Extend the JPanel class and create an array of 52 cards. Add four sets of numbers from 1 to 10. Use J for Jack, Q for queen, K for king, and A for ace. Jack through king will have a value of 10, and the ace will have a value of 11. Deal two cards to the user and two cards to the computer. Do not show the value of the computer's first two cards to the user. Add buttons Hit, Stay, and Reset. If the user selects the "Hit" button, randomly select one of the cards from the array, and give it to the user. (After selecting a card, do not reuse this index during the rest of the game.) If the dealer has less than 21, "hit" the dealer, too. When the user selects the "Stay" button, add up the card values. The winner is the person who is closest to 21 without going over.

- Java Program Requirements: Create a DodecahedronList class that stores the name of the list and an ArrayList of Dodecahedron objects. It also includes methods that return the name of the list, number of Dodecahedron objects in the DodecahedronList, total surface area, total volume, average surface area, average volume, and average surface to volume ratio for all Dodecahedron objects in the DodecahedronList. The toString method returns a String containing the name of the list followed by each Dodecahedron in the ArrayList, and a summaryInfo method returns summary information about the list. Design: The DodecahedronList class has two fields, a constructor, and methods as outlined below. (1) Fields (instance variables): a String representing the name of the list and an ArrayList of Dodecahedron objects. These are the only fields (instance variables) that this class should have. (2) Constructor: Your DodecahedronList class must contain a constructor that accepts a parameter of type String…arrow_forwardTrue/False 6.
