Path - Problems/ShoppingCart.java

Issue Description:
The calculateTotalPrice function in the ShoppingCart.java file is throwing a NullPointerException when an item in the shopping cart has a null price. This issue needs to be resolved to ensure the correct calculation of the total price.

Steps to Reproduce:

Execute the calculateTotalPrice function in Java with a shopping cart containing an item with a null price.
Expected Behavior:
The function should handle items with null prices gracefully and calculate the total price correctly.

Actual Behavior:
The function throws a NullPointerException when encountering an item with a null price, causing the calculation to fail.

Proposed Solution:
To resolve this issue, we need to modify the calculateTotalPrice function in the ShoppingCart.java file to check for null prices before adding them to the total. If an item has a null price, it should be skipped in the calculation.
This modification ensures that items with null prices are excluded from the calculation, preventing the NullPointerException.

Additional Information:

Relevant code file: ShoppingCart.java
Environment: Java 8, ShoppingCart version 1.2.3
Labels: bug, NullPointerException

Rock-paper-scissors is a hand-based game between two players, in which each player simultaneously forms one of three shapes with an outstretched hand. These shapes are "rock" (a closed fist), "paper" (a flat hand), and "scissors" (a fist with the index and middle fingers extended).

The game has only three possible outcomes:

Rock beats scissors (rock crushes scissors)
Scissors beats paper (scissors cuts paper)
Paper beats rock (paper covers rock)
If both players choose the same shape, the game is a tie.

The game is often played as a best-of-three series, but it can also be played as a single round.

Rock-paper-scissors is a simple game, but it is also a lot of fun. It is a great game to play with friends and family, and it can be enjoyed by people of all ages.

make the intro of the game such that I making that game in python language

Sure, here is a more intro of the game explaining how I'm making it in Python:

I'm making a rock-paper-scissors game in Python. This is a classic two-player game where each player chooses one of three shapes: rock, paper, or scissors. The winner is determined by the following rules:

Rock beats scissors
Scissors beats paper
Paper beats rock
If both players choose the same shape, the game is a tie.

I'm using Python to make this game because it is a popular and versatile language. It is also relatively easy to learn, making it a good choice for beginners.

To make the game, I'll start by importing the random module. This module allows us to generate random numbers, which we'll need to use to determine the computer's choice.

Next, I'll create a function to generate a random choice for the computer. This function will simply return one of the three shapes at random.

Then, I'll create a function to get the player's choice. This function will prompt the player to enter their choice and then return it.

Finally, I'll create a function to determine the winner of the game. This function will take the player's choice and the computer's choice as input and then return the winner.

Once I have all of these functions written, I can put them together to make the game. The game loop will simply prompt the player to enter their choice, generate the computer's choice, and then determine the winner. The game will continue until one player wins three rounds.

Your review and insights are vital as we enhance the repository's utility.

Happy coding :)

Fast Modular Exponentiation is a high-performance technique used in computer science and cryptography to swiftly compute massive modular exponentiations. It is especially handy when working with big numbers since it decreases the amount of multiplications and intermediate results required to perform the modular exponentiation.
