//Question i
System.out.printf( "The value of x is %d\n", x );
int x = 2;
//Question ii
System.out.printf( "\nThe value of x is is %d\n", x );
} // end method begin

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.
Write a program that lets a lecturer keep track of test scores for their students. Your program should begin by asking the lecturer for a number of students in their class as well as the total number of exams that will be given to the class. Validate this information to ensure that the numbers entered are positive.
Next, give the message to lecturer to enter scores for each student. Make sure that the values entered are valid (marks cannot be neagtive) —if they aren’t you will need to prompt them again. You may need to use nested loops for this; a “while” loop can be placed inside of a “for” loop as necessary.
Once your program has collected all exam scores for a student it should display that student’s average and move on to the next student. When all students have been calculated the program should compute the overall average score for the entire class.
Write a program in BASIC that compute total charges for phones sold and displays this information to the screen.
The program must prompt the user for the price of a phone. Compute the sales tax for this value, and then display the phone price, the dollar amount of the sales tax, and the total charge for this purchase. Sales tax is calculated as 7% of the price of the phone. Total charge is the price plus the sales tax amount.
After all the data has been entered, display a grand total of number of phones sold, and a grand total of all total charges.
This program must use at least two subroutines.
Explain disadvantages associated with Virtual reality.
