Armstrong Atlantic State University
Instructor: Dr. Y. Daniel Liang
Please note that the university policy prohibits giving the exam score by email. If you need to know your
final exam score, come to see me during my office hours next semester.
I pledge by honor that I will not discuss the contents of this exam with
anyone.
Signed by ___________________ Date ___________________
Part I. (2 pts each)
a. How many times is the following loop body repeated? What is the
output of the loop?
int i = 0;
while (i < 10) {
if ((i + 1) % 2 == 0)
System.out.println(i);
i++;
}
b. Convert the following for loop into a do-while loop.
int sum = 0;
for (int i = 0; i < 100; i++) {
sum += i;
}
c. Convert the following if statement using a switch statement
// Find interest rate based on year
if (numOfYears == 7)
annualInterestRate = 7.25;
else if (numOfYears == 15)
annualInterestRate = 8.50;
else if (numOfYears == 30)
annualInterestRate = 9.0;
else {
System.out.println("Wrong number of years");
System.exit(0);
}
Part II: Show the output of the following code:
a: (2 pts)
}
System.out.println("number is " + number
Part III: (Write programs)
1. (15 pts) Write a program that prompts the user to enter
an integer n (assume n >= 2) and displays its largest
factor other than itself.
2. (15 pts) Write a method to display a pattern as follows:
1
4 1
9 4 1
16 9 4 1
25 16 9 4 1
...
n*n ... 36 25 16 9 4 1
The method header is
public static void displayPattern(int n)
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
// Enter the number of lines
System.out.print("Enter n: ");
int n = input.nextInt();
7
3. (15 pts) Write the following method that returns true if the list is already sorted in
increasing order.
public static boolean isSorted(int[] list)
Write a test program that prompts the user to enter a list
and displays whether the list is sorted or not. Here is a
sample run. Note that the first number in the input
indicates the number of the elements in the list.
<Output>
Enter list: 8 10 1 5 16 61 9 11 1
The list is not sorted
<End Output>
<Output>
Enter list: 10 1 1 3 4 4 5 7 9 11 21
The list is already sorted
<End Output>
See the next page for the outline of the program:
public class Test {
public static void main(String[] args) {
// Fill in the code here
4. (15 pts) (Occurrences of a specified character) Write a
method that finds the number of occurrences of a specified
character in the string using the following header:
public static int count(String str, char a)
Part IV: Multiple Choice Questions: (1 pts each)

System.out.println("too cold");
