Often, programmers list the constructor first because it is the first method used when an object is created.
A constructor is a unique method of the class that is executed when an instance of a class is created. It has the same name as the class and is created as a separate method. The constructor is also used to assign values to variables when the object is created. You can define constructors with or without parameters. The object's properties and variables can be initialized with the help of a constructor. Here's an example of how to create a constructor:
class Car {
String name;
int model_number;
Car(String name, int model_number) {
// The constructorthis.name = name;
this.model_number = model_number;
}
public static void main(String[] args) {
Car car1 = new Car("BMW", 11);
Car car2 = new Car("Audi", 2021);
System.out.println(car1.name + " " + car1.model_number);
System.out.println(car2.name + " " + car2.model_number);
}
}
As we have defined a constructor for the Car class and used the Car object to initialize the name and model_number properties.

6. The UDP destination port number identifies the application or service on the handle data returning to the PC establishing a session with the server. overhead server which will handle the data.
The correct answer is TCP and UDP are two transport layer protocols that are used for sending data over a network. The following three statements correctly describe their functions:
The TCP source port number identifies the sending host on the network: TCP uses a 16-bit source port field to identify the sending process or application on the host. This helps the receiving host to identify the source of the data. UDP segments are encapsulated within IP packets for transport across the network: UDP does not have any built-in error recovery mechanism, so it simply encapsulates its segments within IP packets and sends them over the network. The source port field identifies the running application or service that will handle data returning to the PC establishing a session with the server: Both TCP and UDP use the source and destination port fields to identify the applications or services that will handle the data. The source port field helps the server to identify the process or application that sent the data and establish a session with the PC. In summary, TCP and UDP are transport layer protocols that use source and destination port numbers to identify the sending and receiving hosts and the applications or services that will handle the data. UDP simply encapsulates its segments within IP packets, while TCP establishes a reliable, connection-oriented session between the hosts.

Question 1 Write an application that displays a menu of five items in a Samzo restaurant as follows: ********Welcome to Samzo Restaurant Menu********** (1) Milk R10.99 (2) Coke R21.00 (3) Chips R22.75 (4) Bread R11.50 (5) Pap & Steak R43.00 ***Enjoy your meal... Thank you*** Prompt the user to choose an item using the number (1, 2, 3, 4 or 5) that corresponds to the items in the menu, or to enter 0 to quit the application. The program should then display the name and price of the selected item.
Here's a Python program that displays the Samzo Restaurant menu and prompts the user to make a selection:
The Programprint("********Welcome to Samzo Restaurant Menu**********")
print("(1) Milk R10.99")
print("(2) Coke R21.00")
print("(3) Chips R22.75")
print("(4) Bread R11.50")
print("(5) Pap & Steak R43.00")
while True:
selection = int(input("Please enter a number (1-5) to select an item, or 0 to quit: "))
if selection == 0:
print("Thank you for visiting Samzo Restaurant!")
break
elif selection == 1:
print("You have selected Milk for R10.99")
elif selection == 2:
print("You have selected Coke for R21.00")
elif selection == 3:
print("You have selected Chips for R22.75")
elif selection == 4:
print("You have selected Bread for R11.50")
elif selection == 5:
print("You have selected Pap & Steak for R43.00")
else:
print("Invalid selection. Please try again.")
This program uses a while loop to repeatedly prompt the user for a selection until they enter 0 to quit. It uses an if statement to determine which menu item was selected based on the number entered by the user, and then displays the name and price of the selected item.
If the user enters an invalid selection (i.e. a number outside of the range 0-5), the program displays an error message and prompts the user to try again.

How can we improve the following program?
function start() {
move();
move();
move();
move();
move();
move();
move();
move();
move();
}
Answer:
Your professor may be looking for something simple. I am not sure the caliber your professor is expecting. But for a basic. You could make a simple loop to improve the code.
function start() {
for (var i = 0; i < 9; i++) {
move();
}
}
With less text, this code will do the same task as the original program. We can prevent repeatedly repeating the same code by utilizing a loop.
From there you could make the moves dynamic...
function start(numMoves) {
for (var i = 0; i < numMoves; i++) {
move();
}
}
This passes the number of mes as an argument..the code will move forward a specified number of times based on the value of the numMoves parameter.
Then from there we could add error handling to have it catch and handle any errors that may occur. This of course is if the move() function displays an error.
function start(numMoves) {
try {
for (var i = 0; i < numMoves; i++) {
move();
}
} catch (e) {
console.error(e);
}
}
BONUS
Here is a combined executable code...explanation below...
// Define the move function
function move() {
console.log("Moving forward");
}
// Define the start function
function start(numMoves) {
try {
for (var i = 0; i < numMoves; i++) {
move();
}
} catch (e) {
console.error(e);
}
}
// Call the start function with 9 as an argument
start(9);
Explanation for bonus:
The move() and start() functions are defined in the code.
A message indicating that the object is moving forward is logged to the console by the straightforward move() function. The start() function calls this function.
Start() only accepts one argument, numMoves, which defines how many times to advance the object. To deal with any errors that might arise when calling the move() method, the function employs a try...catch block.
Based on the value of numMoves, the move() method is called a given number of times using the for loop.
Lastly, the object is advanced nine times by calling the start() procedure with the value 9.
This code requires that the move() function is defined someplace else in the code, or is provided by the environment where the code is being executed (such as a browser or Node.js).
When this code is executed, the start() function is invoked with the input 9 and the object is advanced nine times. Every time the loop executes, the move() function is invoked, which reports a message to the console indicating that the object is moving ahead. Any mistakes that can arise when invoking the move() function are caught and recorded to the console thanks to the try...catch block.

For this question, you need to implement a simple linear regression from scratch without using a library. The linear equation that you need to use for this exercise is y=50x+22, which you will use to generate some synthetic data with random variation to make the problem interesting.
Lets discuss more in detail.
To begin, you need to randomly select 20 x values between 0 and 100 using a uniform distribution. To do this, you can use a for loop to iterate through the range of 0 to 100 and randomly select 20 x values.
Once you have your x values, you can then use the linear equation of y=50x+22 to calculate the corresponding y values. Finally, you can use these x and y values to create a linear regression and check if it rounds to the original equation.
Grading criteria: The result of your linear regression should round to the original equation. It is not expected to be perfect.
