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.
6
2. (15 pts) Write a method to display a pattern as follows:
1
41
941
16941
2516941
…
n*n…362516941
The method header is
public static void displayPattern(int n)
import java.util.Scanner;
}
}

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.

__________ value.
A. int
B. long
C. byte
D. double
#
3. What is the result of 45 / 4?
#
4. In Java, the word true is ________.
A. a Boolean literal
B. a Java keyword
C. same as value 0
D. same as value 1
#
5. The following code displays ___________.
double temperature = 50;
10
System.out.println(“too cold”);
else
System.out.println(“just right”);
A. too hot
B. too cold
C. too hot too cold just right
D. just right
#
6. The “less than or equal to” comparison operator in Java is __________.
A. <<
B. =<
#
7. Analyze the following code fragments that assign a boolean value to the variable even.
Code 1:
if (number % 2 == 0)
even = true;
else
even = false;
Code 2:
even = (number % 2 == 0) ? true: false;
Code 3:
even = number % 2 == 0;
A. Code 3 has a syntax error, because you attempt to assign number to even.
B. Code 2 has a syntax error, because you cannot have true and false literals in the
#
8. How many times will the following code print “Welcome to Java”?
int count = 0;
do {
System.out.println(“Welcome to Java”);
} while (count++ < 10);
A. 10
B. 8
C. 0
D. 9
E. 11
#
9. What is the value in count after the following loop is executed?
int count = 0;
do {
System.out.println(“Welcome to Java”);
} while (count++ < 9);
System.out.println(count);
#

// iteration
}
A. 2*n
B. n
C. n – 1
D. n + 1

#
14. Analyze the following code.
public class Test {
public static void main(String[] args) {
System.out.println(max(1, 2));
}
public static double max(int num1, double num2) {
System.out.println(“max(int, double) is invoked”);
if (num1 > num2)
return num1;
else
return num2;
}
13
}
}
A. The program runs and prints 2 followed by “max(double, int)” is invoked.
B. The program cannot compile because the compiler cannot determine which max
method should be invoked.
#
15. Analyze the following code:

return n;
}
}
