CS 151 serves as a foundational class to teach students the essentials of programming. The foundational concepts that CS 151 teaches are variables, data types and expressions, assignment, control-flow statements, I/O, exception handling, functions, arrays, and classes.

Here are some examples of the kind of coding that CS 151 entails.

import java.util.*;
public class Midterm1 {

	public static void main(String[] args) {
		// Jadyn Richardson
		// 01221594
		System.out.print("How many packages were purchased? ");
		Scanner input = new Scanner (System.in);
		// variable for the user to input how many products will be purchased
		int quantity = input.nextInt();
		input.close();
		// creating variables for all of the numbers that will be calculated
		double discount = 0;
		// the price of each item is 99$
		double sum = quantity * 99;
		double amountDiscounted = 0;
		String qualifier = " ";
		double discountedSum = 0;
		// if the quantity of the items is in between the two specified numbers, the discount variable is set to the specified numbers in the parameters of the project
		if(quantity >= 10 && quantity <=19)
			discount = .2;
		else if (quantity >= 20 && quantity <= 49)
			discount = .3;
		else if (quantity >= 50 && quantity <= 49)
			discount = .4;
		else if (quantity >= 100)
			discount = .5;
		else
			discount = 1;
		// // the qualifier line is a string that prints out what discount the user will get in percentage form
		qualifier = "this purchase qualifies for a " + discount*100 + "% discount ";
		// the discounted sum is calculated by taking the sum - (sum * discount)
		discountedSum = sum - (sum * discount);
		// the amount discounted is the sum * discount
		amountDiscounted = (sum * discount);
		// printing out results
		System.out.println(qualifier);
		System.out.println("the total amount of the discount is: " + amountDiscounted);
		System.out.println("The total amount of the purchase is: " + discountedSum);
	}
