Factor that are to be considered in writing the conditional expression:
- It is recommended to use simple column or literal as operands in a conditional expression.
- Numeric comparisons are made faster when compared with the characters, date and null characters.
- Equality expression will be processed in a faster rate when compared with inequality expressions.
- Use literals in place of the conditional expressions.
- Specify False condition first when multiple AND condition is used.
- Specify True condition first when multiple OR condition is used.
- Usage of NOT logical operation is avoided.

- 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()).
