Consider an online food delivery service, such as Seamless. Customers and Items are represented by the classes given below. Your task is to create an Order class that will contain information about the customer, an ArrayList of items, and the restaurant name. Create the following methods: - a constructor to initialize these attributes - computeTotal method to compute the total of all items - showOrder method to display the information about the customer, items, and order, including the total public class Customer { private String name; private String phone; private String address; public Customer(String name, String phone, String address) { this.name
Answers
Answer:
Explanation:
Since none of the classes were provided in the question I created all of the classes so that the program works as requested in the question. I also created a test order so that you can see the output of the program in the attached picture below.

Item item1 = new Item("banana", 1, 3);
Item item2 = new Item("apple", 0.5, 6);
Item item3 = new Item("grapes", 2, 3);
items.add(item1);
items.add(item2);
items.add(item3);
Customer customer = new Customer("John", "9085526269", "123 Inslee");
Order myOrder = new Order(customer, items, "Grocery");
myOrder.showOrder();
}
}
class Order {
Customer customer;
ArrayList<Item> items = new ArrayList<>();
String restaurant;
public Order(Customer customer, ArrayList items, String restaurant) {
this.customer = customer;
this.items = items;
this.restaurant = restaurant;

public void showOrder() {
System.out.println(restaurant);
System.out.println("Name: " + customer.getName());
System.out.println("Phone: " + customer.getPhone());
System.out.println("Address: " + customer.getAddress());
for (Item x :items) {
System.out.println(x.itemName + " : " + x.quantity);
}
computeTotal();
}
}
class Item {
String itemName;
double costPerItem;
int quantity;
public Item(String itemName, double costPerItem, int quantity) {
this.itemName = itemName;
this.costPerItem = costPerItem;
this.quantity = quantity;
}
public double total() {
double total = costPerItem * quantity;
return total;
}

class Customer {
private String name;
private String phone;
private String address;
public String getName() {
return name;

Directions :: Write a Ship class. Ship will have x, y, and speed properties. x, y, and speed are integer numbers. You must provide 3 constructors, an equals, and a toString for class Ship.
One constructor must be a default.
One constructor must be an x and y only constructor.
One constructor must be an x, y, and speed constructor.
Provide all accessor and mutator methods needed to complete the class.
Add a increaseSpeed method to make the Ship speed up according to a parameter passed in.
Provide an equals method to determine if 2 Ships are the same(i.e. in the same location).
You also must provide a toString() method.
The toString() should return the x, y, and speed of the Ship.
In order to test your newly created class, you must create another class called ShipRunner. There you will code in the main method and create at least 2 Ship objects (although you can create more if you like), using the constructors you created in the Ship class. Then you will print them out using the toString method and compare them with the equals method.

Which of the following devices can store large amounts of electricity, even when unplugged?
LCD monitor
DVD optical drive
CRT monitor
Hard disk drive
Answers
Even when unplugged, a CRT (Cathode Ray Tube) monitor can store a lot of electricity. The capacitors within CRT monitors can store enough power to be fatal, thus you should never open one.
What does CRT stand for?An electron beam striking a phosphorescent surface creates images in a cathode-ray tube (CRT), a specialized vacuum tube. CRTs are typically used for desktop computer displays. The "picture tube" in a television receiver is comparable to the CRT in a computer display.
What characteristics does CRT have?Flat screen, touch screen, anti-reflective coating, non-interlaced, industrial metal cabinet, and digital video input signal are typical features of CRT monitors. As opposed to the typically curved screen found in most CRT displays, the monitor's screen can be (almost) flat.

Answer:
CRT monitor
Explanation:
A cathode ray tube (CRT) monitor can store large amounts of electricity, even when unplugged. You should never open a CRT monitor, as the capacitors within the CRT can store enough electricity to be lethal.
LCD monitors do not use large capacitors and are much safer to work on than CRT monitors (although the CCFL backlight has mercury vapor in it, which could be harmful if the tube is broken).
DVD optical drives and hard disk drives do not store electricity in sufficient quantity to be harmful.

Answers
The steps to Build a sequential circuit that contains a register is given below
The first step is to connect the 4-bit INDATA input to the data input of a 4-bit register.Next, we need to connect the Load and Enable inputs to a multiplexer. The multiplexer will be used to select between the INDATA input and the output of the register.The multiplexer output should be connected to the input of the register.We also need to create an AND gate that will be used to trigger the register on the falling edge of the clock. The AND gate should have the Clock input as well as the Enable input as its inputs.The output of the AND gate should be connected to the clock input of the register.The output of the register should be connected to the OUTDATA output.Create a NOT gate and connect the Load input to it, and connect the output of the NOT gate to one of the multiplexer input.Connect the output of the register to the second input of the multiplexer.What is the design board about?To build a sequential circuit that contains a register, we can use a combination of logic gates, flip-flops, and multiplexers.
In the above way, the register will be updated every clock cycle in which the Enable input is high. If the Load input is low, the multiplexer will select the output of the register and it will be incremented.
Otherwise, the multiplexer will select the INDATA input and the register will be loaded with the data asserted on the INDATA pin. The output of the register will be connected to the OUTDATA output, providing the register data.

Write a procedure ConvertToBinary that takes an input as a number from 0 to 16 (including 0 but not 16) and converts it to a binary number. The binary number should be returned as a list.
Answers
Sure, here's an example of a Python function that converts a decimal number to binary and returns the result as a list:
def ConvertToBinary(decimal):
binary = []
while decimal > 0:
remainder = decimal % 2
binary.append(remainder)
decimal = decimal // 2
return binary[::-1]
The function takes in an input decimal which is a number between 0 and 16 (not including 16) and uses a while loop to repeatedly divide the decimal number by 2 and take the remainder. The remainders are then appended to a list binary. Since the remainders are appended to the list in reverse order, the result is reversed by slicing the list [-1::-1] to give the proper order.
You can also add a check to make sure that the input is within the required range:
def ConvertToBinary(decimal):
if decimal < 0 or decimal >= 16:
return None
binary = []
while decimal > 0:
remainder = decimal % 2
binary.append(remainder)
decimal = decimal // 2
return binary[::-1]
this way you can make sure that the input provided is within the allowed range.

In this task, we will be finding a possible solution to number puzzles like 'SAVE' + 'MORE' = 'MONEY'. Each alphabet represents a digit. You are required to implement a function addition_puzzle that returns a dictionary containing alphabet-digit mappings that satisfy the equation. Note that if there are multiple solutions, you can return any valid solution. If there is no solution, then your function should return False.
>>> addition_puzzle('ANT', 'MAN', 'COOL')
{'A': 8, 'C': 1, 'L': 9, 'M': 6, 'N': 7, 'O': 5, 'T': 2}
>>> addition_puzzle('AB', 'CD', 'E')
False
Explanations:
ANT + MAN = COOL: 872 + 687 = 1559
AB + CD = E: The sum of two 2-digit numbers must be at least a two-digit number.
Your solution needs to satisfy 2 conditions:
The leftmost letter cannot be zero in any word.
There must be a one-to-one mapping between letters and digits. In other words, if you choose the digit 6 for the letter M, then all of the M's in the puzzle must be 6 and no other letter can be a 6.
addition_puzzle takes in at least 3 arguments. The last argument is the sum of all the previous arguments.
Note: The test cases are small enough, don't worry too much about whether or not your code will run within the time limit.
def addition_puzzle(*args):
pass # your code here
Answers
Answer:
Here is one possible solution to this problem in Python:
from itertools import permutations
def addition_puzzle(*args):
# Get all permutations of the digits 0-9
digits = list(range(10))
all_permutations = list(permutations(digits))
# Iterate through each permutation
for perm in all_permutations:
# Create a dictionary mapping each alphabet to a digit
mapping = {alphabet: digit for alphabet, digit in zip(args[0], perm)}
if all(mapping[alphabet] != 0 for alphabet in args[0]):
# Check if the sum of the numbers is equal to the last argument
num1 = int(''.join(str(mapping[alphabet]) for alphabet in args[1]))
num2 = int(''.join(str(mapping[alphabet]) for alphabet in args[2]))
if num1 + num2 == int(''.join(str(mapping[alphabet]) for alphabet in args[3])):
return mapping
# If no solution is found, return False
return False
print(addition_puzzle('ANT', 'MAN', 'COOL'))
print(addition_puzzle('AB', 'CD', 'E'))
Explanation:
This solution first generates all possible permutations of the digits 0-9 using the permutations function from the itertools module. Then, it iterates through each permutation and creates a dictionary mapping each alphabet to a digit. It checks if the leftmost letter in any word is not zero and if the sum of the numbers is equal to the last argument. If both conditions are satisfied, it returns the mapping. If no solution is found after iterating through all permutations, it returns False.
