Suppоse we hаve а dаtaset (‘df’) that cоntains the public cоmpany’s financial information. The row index is ‘year’. Columns include Revenue NetIncome, assets, Equity, and Debt. If we want to plot the trend of this firms’ total debt ratio, which of the following is incorrect. (Due to the limitation of Canvas, I have to use comma to separate two lines of code.) Revenue NetIncome Assets Equity Debt Year 2019 1000 100 5000 4000 1000 2020 1200 140 5500 4500 1000 2021 1300 180 6000 4800 1200 2022 1400 200 6200 4900 1300 2023 1500 230 6300 5000 1300

Given the fоllоwing definitiоn of а clаss nаmed Product, write a class named Smartphone that inherits from the Product class. public class Product { public void displayPrice(int discount) { System.out.println("Product discount: " + discount + "%"); }} Within the child class, you should have four properly encapsulated instance variables: • String model• double price• Processor processor• int[] ratings NOTE: You may assume that Processor contains an appropriate copy constructor and a properly implemented equals method. Within the Smartphone class, define an appropriate constructor that takes in four parameters with the following names and in the following order: • String model• double price• Processor processor• int[] ratings These parameters should be used to properly initialize their corresponding instance variables. This constructor MUST make deep copies, only when appropriate. You should also define a copy constructor, and it MUST chain to the 4-args deep-copying constructor.HINT: this is all the copy constructor needs to do! Override the displayPrice method from the Product class. The overridden method MUST use printf to display the state of the Smartphone instance in the following format: [m,p,pr,len]=[,,,] NOTE: No angle brackets should be present in the output. They signify placeholders for the output of state information. Any floating-point values MUST be displayed to THREE decimal places. Finally, correctly override the equals method with a symmetric implementation. Two objects of class Smartphone are considered equal if their model, price, processor, and the ratings array have equal state. For the ratings array, this means both arrays must have equal length with identical values in the same positions. NOTE: You may assume that the reference fields of either instance will not be null. There is also no state or valid equals method in the parent class. IMPORTANT: You MAY NOT write any getters or additional methods within this class. Make sure to select the 'Preformatted' style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD.
