Chapter 7, Problem 1CTQ
Program Plan Intro
Radio Frequency Identification (RFID):
- RFID is typically implemented with the help of radio waves for communicating information between an item and a system.
- A classic RFID system has a reader, chips or tags, and an antenna. The system can be either passive or active.
- Active RFID has a battery and transmits information periodically with higher range than a passive RFID.
- Chips are powered by electromagnetic induction through the reader. Once the chip is powered by the RFID reader, it reacts by transferring its information.
Explanation of Solution
Comparison of two examples of RFID readers:
Comparison of two examples of RFID readers are listed in the table below:
| Comparison features | Ultra-High Frequency (UHF) RFID reader | High Frequency (HF) RFID reader |
|
Definition | UHF uses single worldwide generation 2 standard. | HF uses multiple standards... |
Explanation of Solution
Handheld options:
“Yes”, handheld options for RFID readers are readily accessible for clerks to checkout customers and to use on the store...
Explanation of Solution
Merits of implementing RFID:
- Range of scan
- RFID capabilities.
- Convenience and speed...

Write a complete Java program named FindSumAndAverage that performs the following tasks in 2-D array:
Main Method:
a. The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns.
b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9.
c. The main method then calls another method named printMatrix() to display the matrix in a matrix format.
d. The main method also calls a method named findSumAndAverage() which:
• Receives the generated matrix as input.
• Calculates the sum of all elements in the matrix.
• Calculates the average value of the elements in the matrix.
• Stores these values (sum and average) in a single-dimensional array and returns this array
• e. The main method prints the sum and average based on the result returned from findSumAndAverage()).
