2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For
example 12 and 13 are relatively prime, but 12 and 14 are not.
a. Write a method called relativelyPrime that accepts two integer parameters A and B. The
method should output if A, and B are relatively prime or nat.
Use the following method header:
public static void relativelyPrime(int A, int B)
b. Write a test program (main) to test the method by asking the user to input two positive
integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are
relatively prime or not.
Sample Run 1:
Enter Two positive integers X and Y: 12 13
12 and 13 are relatively prime
Sample Run 2:
Enter Two positive integers X and Y: 12 14
12 and 14 are not relatively prime
42) Look at the following method:
public static int test2 (int x, int y)
if (x < y)
{
return -5;
}
else
{
return (test2 (x - y, y + 5) + 6) ;
}
}
What is returned for test2 (10, 20)?
A) -5
B) 1
C) 6
D) 10
43) This term is used for methods that directly call themselves.
A) Simple recursion
C) Absolute recursion
B) Direct recursion
D) Native recursion
44) If the base case in a recursive method is never reached:
A) The result will always be off by one.
C) The method will call itself indefinitely.
B) The method will call itself only once.
D) The method will never call itself.
45) A(n) is an object that is generated in memory as the result of an error or an unexpected
event.
A) exception
C) default exception handler
B) exception handler
D) error message
46) All of the exceptions that you will handle are instances of classes that extend this class.
A) Exception
C) IOException
B) RunTimeException
D) Error
47) All exceptions are instances of dasses that extend this class.
A) Throwable
