Q5.2
Suppose that the file input.txt contained the following:
123
456
789
987
654
321
What would be printed by executing the following command?
$ java E2b < input.txt I java E2b
Also, explain what this command does.
Enter your answer here

Q5.1 Write a program E2b
Write a Java program called E2b that will read from Stdln an integer, n, and will set the size of a
2D array to have n rows and n columns. The values in this n xn 2D array must be read from
Stdln and the array must be filled in row-major order.
For example, if the following input stream was read: 4 1234 4321 9876 5764
The 2D array created would be:
2
4
3
2
1
9.
8
7
6
4
Include in the program above, code that would print the values in the 2D array beginning with
the value in the last row, last column and ending with the value in the Oth row, Oth column,
traversing the columns from bottom to top, printing n values in each row of the output. The
values In the array do not change. You are simply printing them in a unique order.
For example, for the array given above, the output would be:
4
6
1
4
6
7
8
3
2
4
1
public class E2b
public static void main(String[] args)

Write a program that reads integers user_num and div_num as input, and output the quotient (user_num divided by div_num). Use a try block to perform all the statements. Use an except block to catch any ZeroDivisionError as a variable and output "Zero Division Exception: " followed by the exception message from the variable. Use another except block to catch any ValueError caused by invalid input as a variable and output "Input Exception: " followed by the exception message from the variable. Note: ZeroDivisionError is raised when a division by zero happens. ValueError is raised when a user enters a value of different data type than what is defined in the program. Do not include code to raise any exception in the program. (in Python)
