: Symbol Balance-Define a class called SymbolBalance in the provided empty SymbolBalance.java file.Your SymbolBalance class will read through a Java file and check for simple syntatical errors. You should write two methods, as specified by the SymbolBalanceInterface which you must implement for full credit.The first method, setFile, should take in a String representing the path to the file that should be checked.The second method, checkFile, should read in the file character by character and check to make sure that all { }’s, ( )'s, [ ]'s, " "’s, and /* */’s are properly balanced. Make sure to ignore characters within literal strings (" ") and comment blocks (/* */). Process the file by iterating through it one character at a time. During iteration, the symbol currently pointed to in the loop will be referred to as henceforth.You do not need to handle single line comments (those that start with //), literal characters (things in single quotes), or the diamond operator(<>).There are three types of errors that can be encountered:The file ends with one or more opening symbols missing their corresponding closing symbols.There is a closing symbol without an opening symbol.There is a mismatch between closing and opening symbols (for example: { [ } ] ).Once you encounter an error, return a BalanceError object containing error information. Each error type has its own class that descends from BalanceError and each has its own required parameters:Symbol mismatch after popping stack: return MismatchError(int lineNumber, char currentSymbol, char symbolPopped)Empty stack popped: EmptyStackError(int lineNumber)Non-empty stack after parsing entire file: NonEmptyStackError(char topElement, int sizeOfStack)If no error is found, return null.Only push and pop the * character to the stack when handling multi-line comments. Do not push the / character or the string \*.You must use your MyStack from Problem 1 in this problem.We have provided you with a number of test inputs in the sub-folder TestFiles. We will use our own test files to grade your performance on all conditions - those files will be released after the assignment is due.-public interface SymbolBalanceInterface {public void setFile(String filename);public BalanceError checkFile(); // returns either MismatchError(int lineNumber, char currentSymbol, char symbolPopped)// EmptyStackError(int lineNumber),// NonEmptyStackError(char topElement, int sizeOfStack).// All three classes implement BalanceError}-public interface MyStackInterface {public void push(T x);public T pop();public T peek();public boolean isEmpty();public int size();}
Answers
To implement the Symbol Balance class, you need to define the class and have it implement the Symbol Balance Interface.
The set file method takes a String representing the file path to be checked. The check File method reads the file character by character and ensures that all { }, ( ), [ ], " ", and /* */ symbols are properly balanced while ignoring characters within literal strings and comment blocks.
To process the file, iterate through it one character at a time and handle any errors using Balance Error objects, which include Mismatch Error, Empty Stack Error, and Non Empty Stack Error. If no error is found, return null. Use the My Stack class from Problem 1 to manage the symbols in the file.
The implementation should look something like this:
```java
public class Symbol Balance implements Symbol Balance Interface {
private String filename;
public void set File(String filename) {
this. file name = filename;
}
public Balance Error check File() {
My Stack stack = new My Stack<>();
// Implement the logic to read the file, check symbol balance, and handle errors using Balance Error objects
// If no errors found, return null
return null;
}
}
```
Remember to implement the logic for reading the file and checking the symbol balance using the provided error handling classes. Good luck with your implementation.

In neighbourhood A, there is only one SPA center called JBI SPA. JBI provides a SPA service to their customers where most of whom are living in this neighbourhood and have been contacting with JBI SPA for many years. JBI's demand curve is: P = 30 - Q, and JBI's marginal cost of service is: MC = 4Q. JBI charges a single price for a unit of service.
At profit maximization level, calculate the following:
a) Price Level:_____
b) Output level:_____
c) Consumer surplus: _____
d) If JBI enforces first-degree price discrimination, the lowest priced charged is: ____ and the output level is: _____
e) Ignoring any fixed costs and under perfect price discrimination, JBI's total profit is:_____
Answers
At profit maximization level, the price level, output level and consumer surplus is given as follows:a) Price Level:The profit maximization condition of JBI Spa is given by MR = MC.Substitute the value of MR in terms of P, we have;P/2 = surplus:Consumer surplus (CS) is the difference between what the customers are willing to pay for a good or service and the actual price they pay for it.
The formula for consumer surplus is given as;CS = 0.5 * (Pmax - P) * Q, where Pmax = 30.Substitute the values of P, Pmax, and Q in the above formula, we get;CS = 0.5 * (30 - 8Q*) * Q*CS = 0.5 * (30 - 8(3.33)) * 3.33CS = $37.17d) If JBI enforces first-degree price discrimination, the lowest priced charged is and the output level is:The lowest price charged under first-degree price discrimination is the reservation price, which is equal to the maximum amount of money each customer is willing to pay for the service.
Since most of JBI's customers have been contacting with JBI Spa for many years, we can assume that their maximum willingness to pay is not too different from the price they are currently paying.So, the reservation price under first-degree price discrimination is equal to the current price level, which is P* = 8Q*.The output level under first-degree under perfect price discrimination, JBI's total profit is:Under perfect price discrimination, JBI can extract all the consumer surplus from its customers, which means P = MC = 4Q*.Substitute Q* = 3.33 in the above equation, we have;P = 4(3.33) = $13.33JBI's total profit under perfect price discrimination is equal to the total revenue which is given as;Total revenue = P * Q* = 13.33 * 3.33Total revenue = $44.45Thus, ignoring any fixed costs and under perfect price discrimination, JBI's total profit is $44.45.

Some restrictions include registering all databases containing personal information with the countries in which they are operating, collecting data only with the consent of the subjects, and telling subjects of databases the intended and actual use of the databases.
Discuss the relationship between PAPA framework and GDPR. Which PAPA principles do you see implemented in GDPR? Which are omitted?
Answers
The PAPA framework and GDPR both focus on protecting individuals' privacy and ensuring the responsible use of personal data.
The PAPA framework consists of four principles: Privacy, Accuracy, Property, and Accessibility, while GDPR sets out specific regulations for data protection and privacy.
In terms of implementation, GDPR aligns with several PAPA principles. Firstly, the Privacy principle is central to GDPR as it aims to safeguard individuals' privacy rights by regulating how personal data is collected, processed, and stored. GDPR emphasizes obtaining individuals' consent and providing transparency regarding data usage, which aligns with the PAPA Privacy principle.
Additionally, GDPR addresses the Accuracy principle by requiring organizations to maintain accurate and up-to-date personal data and provide mechanisms for individuals to correct or update their information.
However, the PAPA framework's principles of Property and Accessibility are not explicitly addressed in GDPR. While GDPR focuses on privacy and data protection, it does not specifically cover the property rights associated with personal data or the accessibility of data by individuals.

I use the wrap text feature in Excel daily. What is the difference in how this behaves or is used in Excel versus Word? Please explain in detail the differences and similarities.
Answers
The wrap text feature is an essential tool used to format text, particularly long texts or data within a cell in Microsoft Excel. In this question, we need to explain the difference between how wrap text behaves in Microsoft Excel versus how it is used in Microsoft Word.
Wrap Text in Microsoft Excel: Wrap text in Excel is a formatting option that is used to adjust text or data within a cell. When the text entered exceeds the size of the cell, it can be hard to read, and this is where wrap text comes in handy. Wrap text in Excel automatically formats the data within the cell and adjusts the text size to fit the cell's width. If a cell contains too much data to fit in the column, the cell's text wraps to the next line within the same cell.
To wrap text in Excel, follow these simple steps:
Select the cell or range of cells containing the text that needs wrapping. Right-click on the selected cell and click Format Cells. In the Format Cells dialog box, click on the Alignment tab. Click the Wrap text option and then click OK.Wrap Text in Microsoft Word: In Microsoft Word, the Wrap Text feature is used to format text around images and graphics. It is used to change the way the text flows around the image, allowing users to position images and graphics in the document. Wrap Text in Microsoft Word does not adjust the font size of the text to fit the width of the cell like in Excel.
To wrap text in Microsoft Word, follow these simple steps:
Insert the image in the document. Select the image and go to the Picture Format tab. Click on Wrap Text, and you can choose how you want the text to wrap around the image.The main difference between the use of Wrap Text in Microsoft Excel and Microsoft Word is that Wrap Text in Excel is used to format long data and adjust text size to fit the width of the cell while Wrap Text in Microsoft Word is used to format text around images and graphics.
