In this assignment, you will build a program using techniques from previous CSS courses that counts unique fractions. No new constructs from our readings are expected, and as such, you can complete this program with just a handful of lines (12-25) of code in just one main function. (But do NOT feel that your code needs to be that short!) Note that the use of methods will improve your design and improve your grade. You will need to use loops, ifs, comments, etc., (in other words, structured programming) to complete this assignment and achieve the outcomes listed below. Included below is a sample execution of your program as well as a list of outcomes your program is to implement; notice reduction of fractions is optional in this version of the assignment. Do NOT build any classes (other than your driver, obviously). You are NOT allowed to use any of Java's built-in abstract data types like ArrayList or HashMap or any of that stuff.
Introduction
Your project is to read in a series of fractions from a text file, which will have each line formatted as follows: "A/B". A sample text file is listed below, and the purpose of your program is to read in each fraction and count the number of occurrences for the current fraction. When all the input is consumed (or as the input is consumed), your program will print out its list of unique fraction and their corresponding count – see the output below (and you may assume no blank lines or misleading characters; see the text file link on the website for one of the actual inputs I’ll use when testing your submission).
Sample Text Input
6/3
7/3
6/3
12/6
Sample Console Output
6/3 has a count of 3
7/3 has a count of 1
NOTE: it is also fine (though not required) if your program simplifies the fractions so that the output is:
2/1 has a count of 3
7/3 has a count of 1
---But either way, 6/3 and 12/6 count as the same fraction, so you do need some mechanism for determining if two fractions that look different are actually the same. The only optional part of the assignment is how you display them in the end.

1. When your computer is not in use, the screen should go blank after a moment, and you should be required to log in again when you return. T/F
Answer:
Explanation:
This statement is generally true. Having the screen go blank after a moment of inactivity, and requiring a login to return to the computer, is a common security feature known as screen locking. When a computer is locked, it prevents unauthorized access by requiring a password or other form of authentication before the user can regain access to the computer.
This is a useful feature as it helps to prevent sensitive data from being accessed if the computer is left unattended for an extended period of time. The lock time out can be configured in the settings by the administrator and it can depend on the specific operating system you are using.
On Windows, you can set the lock time out by going to the Power & Sleep settings and then selecting Additional power settings. On MacOS, you can set lock time out by going to System Preferences, Security & Privacy, then General and adjust the setting for "require password" after sleep or screen saver begins
It's important to remember that screen locking does not guarantee total security, but it's an important step towards making sure your computer is secure and you should enable this feature if it's available on your operating system.
SQL is considered difficult to learn; its command set has a vocabulary of more than 300 words.
a. True
b. False
Answer:
Explanation:
a. True
SQL (Structured Query Language) is a programming language used to manage data in relational databases. While it is relatively easy to learn the basic concepts of SQL, it can become more challenging as you learn the more advanced concepts and try to write more complex queries.
The command set for SQL does have a relatively large vocabulary, with over 300 words and commands that can be used to perform various tasks such as creating and modifying tables, inserting, updating and retrieving data from a database. It also can have slight variations depending on the specific implementation of SQL such as ANSI SQL, MySQL SQL, PostgreSQL SQL.
It's not necessarily difficult to learn, but it does take time and practice to become proficient in it. There are many resources available online that can help you learn SQL, such as tutorials, videos, and documentation, and many SQL tutorials are available for free. You can also practice by creating your own small databases and experimenting with different queries.
Write a java program to help the company cover a room with the fewest pieces of carpet needed. The carpet squares all measure an integer number of feet on each edge, and only accepts jobs for rooms with both width (W) and length (L) in integer number of feet. Obviously if a room is perfectly square, the company can finish the job with a single piece of carpet, and the maximum number of carpet squares that would ever be needed is L x W squares, each 1-foot on a side
Here is a sample Java program that calculates the minimum number of carpet squares needed to cover a room with a given width and length:
This program prompts the user to enter the width and length of the room in feet, and then calculates the minimum number of carpet squares needed to cover the floor. It does this by dividing the width and length of the room by the width and length of the carpet squares, and then rounding up to the nearest whole number. Finally, it prints the result to the console.
Note: In this program, the carpet squares are assumed to have a fixed width and length, which are represented by the variables carpetWidth and carpetLength. You will need to set these values to the appropriate dimensions for your carpet squares.
