consider the followinfg statement

You are working on a data analysis project where you need to process an array of opening
stock prices containing 10 days of data as float datatype.
Question:
Consider a scenario where you have been given an array of integers representing the daily
stock prices of a company for a given period. You are also provided with an ArrayList of
stock prices for the same period You are required to implement a program that performs the
following tasks:

What do you think would be the correct explanation of the desired outcomes:

Heres my code

import java.util.ArrayList;

public class StockAnalysis {

    // Method to calculate the average stock price
    public static double calculateAveragePrice(float[] prices) {
        double sum = 0;
        for (float price : prices) {
            sum += price;
        }
        return sum / prices.length;
    }

    // Method to find the maximum stock price
    public static float findMaximumPrice(float[] prices) {
        float maxPrice = prices[0];
        for (float price : prices) {
            if (price > maxPrice) {
                maxPrice = price;
            }
        }
        return maxPrice;
    }

    // Method to determine the occurrence count of a specific price
    public static int countOccurrences(float[] prices, float targetPrice) {
        int count = 0;
        for (float price : prices) {
            if (price == targetPrice) {
                count++;
            }
        }
        return count;
    }

    // Method to compute the cumulative sum of stock prices
    public static ArrayList<Float> computeCumulativeSum(ArrayList<Float> prices) {
        ArrayList<Float> cumulativeSum = new ArrayList<>();
        float sum = 0;
        for (float price : prices) {
            sum += price;
            cumulativeSum.add(sum);
        }
        return cumulativeSum;
    }

    // Sample usage
    public static void main(String[] args) {
        // Sample array of stock prices
        float[] stockPrices = {1890.5f, 1500.2f, 1000.9f, 1000.0f, 1000.0f, 1200.0f, 1100.8f, 2100.9f, 1400.2f, 2500.5f};

        // Sample ArrayList of stock prices
        ArrayList<Float> stockPricesList = new ArrayList<>();
        //loop through the array and add stockprice prices in the array to the stockPrices variable
        for (float price : stockPrices) {
            stockPricesList.add(price);
        }

        // Calculate and print the average stock price
        System.out.println("nnAverage Stock Price: " + calculateAveragePrice(stockPrices));

        // Find and print the maximum stock price
        System.out.println("Maximum Stock Price: " + findMaximumPrice(stockPrices));

        // Determine and print the occurrence count of a specific price, in this case 1000.0
        float targetPrice = 1000.0f;
        System.out.println("Occurrences of " + targetPrice + ": " + countOccurrences(stockPrices, targetPrice));

        // Compute and print the cumulative sum of stock prices
        System.out.println("Cumulative Sum of Stock Prices: " + computeCumulativeSum(stockPricesList));
    }
