Question 1 (2 mark) : Write a program called PrintNumberInWord which prints "ONE", "TWO",... ,
"NINE", "OTHER" if the input integer is 1, 2,... , 9, or other, respectively using switch-case statements.
REQUIREMENTS
• Your code must use switch-case statement.
• The user input is always co
ect (input verification is not required).
• Your code must work exactly like the following example (the text in bold indicates the user
input).
Example of the program output:
Example 1:
Please enter an integer: 1
ONE
Example 2:
Please enter an integer: 12
OTHER
Question 2 (4 mark) : Assume there is an enum type variable declared as follows:
enum Day {SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY}
Write a program to ask the user to input an integer, decide and generate the output according to the user
input and the enum variable, and finally display as the example.
REQUIREMENTS
• Your code must use switch-case statement.
• The user input is always co
ect (input verification is not required).
• Your code must work exactly like the following example (the text in bold indicates the user
input).
Example of the program output:
Example 1:
Enter an integer in [1, 7]: 1
You have lecture on MONDAY
Example 2:
Enter an integer in [1, 7]: 2
It is time to review lecture notes and lab exercises
Example 3:
Enter an integer in [1, 7]: 3
You have lab on WEDNESDAY or FRIDAY
Example 4:
Enter an integer in [1, 7]: 4
It is time to review lecture notes and lab exercises
Example 5:
Enter an integer in [1, 7]: 5
You have lab on WEDNESDAY or FRIDAY
Example 6:
Enter an integer in [1, 7]: 6
It is time to review lecture notes and lab exercises.
Example 7:
Enter an integer in [1, 7]: 7
It is time to review lecture notes and lab exercises.
Example 8:
Enter an integer in [1, 7]: 9
Please enter a number in [1, 7]
Example 9:
Enter an integer in [1, 7]: -1
Please enter a number in [1, 7]
Question 3 (4 mark) : Write a program to produce the sum and the average of 1, 2, 3, ..., to N, where N is a
positive integer number entered by the user. The program should use while-loop.
REQUIREMENTS
• Your code must use while-loop statement.
• The user input is always co
ect (input verification is not required).
• Your code must work exactly like the following example (the text in bold indicates the user
input).
Example of the program output (the text in bold indicates the user input):
Example 1:
Please input a positive integer number N: 8
The sum from 1 to 8 is: 36
The average is: 4.5
Example 2:
Please input a positive integer number N: 100
The sum from 1 to 100 is: 5050
The average is: 50.5
Question 4 (2 mark) : Write a program that displays the following pattern using two nested for-
loops.
REQUIREMENTS
• Your code must use nested for-loops.
• Your program should use only the following 3 output statements, one of EACH of the followings:
System.out.print("#");
print #
System.out.print("-");
print -
System.out.println();
print a newline
• The user input is always co
ect (input verification is not required).
• Your code must work exactly like the following example (the text in bold indicates the user
input).
