Using javascript getElementByClass- write a simple programe whereby each time a player gets shot by a bullet, the player loses a life and a 'live' is remove from the three 'lives'.If the player loses all three lives, display and print 'game over'.Display 'play again' message to restart th game.

// Declare data fields: a String named customerName, // an int named numItems, and // a double named totalCost.// Your code here... // Implement the default contructor.// Set the value of customerName to "no name"// and use zero for the other data fields.// Your code here... // Implement the overloaded constructor that// passes new values to all data fields.// Your code here... // Implement method getTotalCost to return the totalCost.// Your code here... // Implement method buyItem.//// Adds itemCost to the total cost and increments// (adds 1 to) the number of items in the cart.//// Parameter: a double itemCost indicating the cost of the item.public void buyItem(double itemCost){// Your code here... }// Implement method applyCoupon.//// Apply a coupon to the total cost of the cart.// - Normal coupon: the unit discount is subtracted ONCE// from the total cost.// - Bonus coupon: the unit discount is subtracted TWICE// from the total cost.// - HOWEVER, a bonus coupon only applies if the…

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);

begin = System.nanoTime(); //we measure in nanoseconds. // put your code here. end = System.nanoTime(); time = end - begin; Page Part 2. f) Create a new StringBuilder Object using no-arg constructor. g) Using for loop to append the array elements one by one to the StringBuilder (one per loop iteration) Hint: to append an element to a StringBuilder, use the append() method in StringBuilder h) Output the StringBuilder on the console. Record a run-time it took to append all integers to the StringBuilder (record run-time of 2.g.)). Please submit a screenshot. The screenshot should match the following example: of 3 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849 it took 59250 nanoseconds to append 50 integers to the StringBuilder.

Q2: Secret Courses Dan's recently announced that he's teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s. Note that if a student is interested in taking multiple courses, they need to send multiple emails, one per course. Upon receiving a message c s, Dan looks at the list of students already enrolled in course c. If there's already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that "a" and "A" are considered the same letter). For example, "Josh" and "Josh" are too similar. "Sam" and…

python >>> feathered_pets=["canary", "parrot", "budgie", "hawk"]>>> furry_pets=["dog", "cat", "ferret", "hamster", "bunny"]>>> all_pets=furry_pets+feathered_pets   what will give me the result ["parrot", "canary", "bunny"]
