- Thank you very much for explaining the absyract concept, it was very helpful and easier to understanc after you explained it. Today we are asked to modify the GridWriter class by adding additional collection style functionality, to throw an exception in case of an error. The GridWriter class should get two new methods: public int size() should return the number of GridItems stored in the GridWriter public GridItem get(int index) should return the stored GridItems by index. Consider the following code. The first line creates a GridWriter object. Then two items are added to the GridWriter. The index of the items will be 0, and 1. Notice how the for loop uses the size and get methods to print out the areas of the two items GridWriter gw = new GridWriter(40, 50); gw.add(new MyCircle(10, 10, 9)); gw.add(new MyRectangle(40, 0, 10, 10)); for (int i = 0; i < gw.size(); i++) { System.out.println(gw.get(i).getArea()); } Once you have these two methods working you…I need help explaining each and every line of the code functionality ========================================================== export const convertBase64 = (file) => { return new Promise((resolve, reject) => { const fileReader = new FileReader(); fileReader.readAsDataURL(file); fileReader.onload = () => { resolve(fileReader.result); }; fileReader.onerror = (error) => { reject(error); }; }); }; export const resizeImage = (base64Str, maxWidth = 500, maxHeight = 500) => { return new Promise((resolve) => { let img = new Image(); img.src = base64Str; img.onload = () => { let canvas = document.createElement("canvas"); const MAX_WIDTH = maxWidth; const MAX_HEIGHT = maxHeight; let width = img.width; let height = img.height; if (width > height) { if (width > MAX_WIDTH) { height *= MAX_WIDTH / width;…Please make a procedure that takes two parameters and prints a list of students from the first parameter as a student ID to the last parameter which is another student ID.

- In python. Please do not copy elsewhere as it is all incorrect, and include docstring so that I can understand the information so I can apply the methods to future problems. Thanks. import the **json** module.Write a class named SatData that reads a [JSON file containing data on 2010 SAT results for New York City](https://data.cityofnewyork.us/api/views/zt9s-n5aj/rows.json?accessType=DOWNLOAD) and writes the data to a text file in CSV format. That same JSON file will be provided as a local file in Gradescope named **sat.json**. Your code does not need to access the internet.CSV is a very simple format - just commas separating columns and newlines separating rows (see note below about commas that are part of field names). You'll see an example of CSV format below. There is a csv module for Python, but you will not use it for this project.Your class should have:* an init method that reads the file and stores it in whatever data member(s) you prefer.

Aside from main, your program should include the following two functions: load_data: Creates a dictionary in which every key is a customer name, and every value is a list containing the amount of each of their sales. Returns the dictionary. print_customer_info: Accepts the dictionary and a customer name as parameters.
