For a class project, Jerome builds a simple circuit with a battery and three light bulbs. On his way to school, Jerome drops his

// Below is Java code. // Package import import java.util.*; // class definition class Main { // class main method public static void main (String[] args) throws java.lang.Exception { try{ // variables final int CENTS_PER_POUND = 25; final int FLAT_FEE_CENTS = 75; // Creating Scanner object for input Scanner sr=new Scanner(System.in); System.out.print("Enter the shipping weight:"); // input reading int shipWeightPounds=sr.nextInt(); // cost calculation int shipCostCents = (shipWeightPounds * CENTS_PER_POUND) + FLAT_FEE_CENTS; // output Weight System.out.println("shipping Weight: " + shipWeightPounds); // output flat fee System.out.println("flat fee of shipping in cents: " + FLAT_FEE_CENTS); // output cents per pound System.out.println("Cents/pound for shipping: " + CENTS_PER_POUND); // output shipping cost System.out.println("total cost of shipping in cents: " + shipCostCents); catch(Exception ex){ return;} } } // Explanation: Define two constants "CENTS_PER_POUND=25" and "FLAT_FEE_CENTS=75". Use a Scanner object to capture user input for weight. Calculate the shipping cost by multiplying the weight with cents per pound and adding the flat fee. Then, display each value.

public static int factorial(int n) { if (n >= 1 && n <=12) { if (n == 1) return 1; else return n * factorial(n - 1); } else return -1; } Explanation: The factorial method takes a single integer n as input. It checks if n is within the range of 1 to 12. If it is, it further checks if n equals 1. If it is indeed 1, it returns 1 as the factorial. Otherwise, it recursively calls itself with n decreased by 1, multiplying the result by n. If n is outside this range, the method returns -1 indicating the input is invalid.

Answer:

//This method takes a parameter called myString of type String

public static boolean isEmailAddress (String myString){

//verifying if the @ character exists in the string

if (myString.indexOf("@")!= -1) {

  //ensuring that only a single instance of @ appears in the string

   if (myString.indexOf("@") == myString.lastIndexOf("@")) {

   //confirming absence of space characters

  if (myString.indexOf(" ") == -1) {

    //checking for the absence of newline characters in the string

    if (myString.indexOf("\n") == -1) {

      //checking for absence of tab characters in the string

      if (myString.indexOf("\t") == -1) {

          return true;

      }

    }

  }

}

}

 return false;

}

Explanation:

The method takes a string presumed to be an email address and verifies whether it is valid, returning true if it is valid and false otherwise. The method checks the following conditions:

->The presence of the "@" character

->Only one occurrence of "@" exists in the string

->No spaces present

->No newline characters present

->No tab characters present

Returning true only if all these conditions are met.

Answer:

Below is the Python code:

stock_prices = input().split() #this takes input and separates it into a list

for price in stock_prices: #this loops through each stock price

   print("$",price) #this outputs each stock price prefixed by a dollar sign

Explanation:

The logic behind the program is clearly outlined in the attached comments. To illustrate the program's workings, let's consider an example:

Imagine the user inputs the stock_prices values of

34.62 76.30 85.05

The input() method captures user input, while the split() method divides the input string, providing a list of strings as:

['34.62', '76.30', '85.05']

Following that, the loop statement for price in stock_prices: iterates through each item in the list, and print("$",price) displays each value from the list on the output screen with a dollar sign, as follows:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05
