Expert Solution & Answer
Chapter 5, Problem 3FTE
Explanation of Solution
Given
//Line 1- Define a method timesTwo()
public static double timesTwo(double num)
{
//Line 2- Compute value
double result = num*2;
}
Methods:
- The methods could be used to break a complex program into small pieces.
- The “void” method simply executes a statements group and then terminates.
- A value returning method would return a value to statement that has called it.
- While calling a method, program would branch to that method.
- It would then execute statements in its body.
- The values that are sent into a method are termed as “arguments”.
- A “parameter” denotes a special variable that holds a value that is being passed into a method.
- The “passed by value” means that only copy of a value of argument is been passed into parameter variable...

Free Response Question:
28. Write a method that will return true if a randomly generated number between 1 and 10 is less than
or equal to 4.
public static boolean FortyPercentOrLess()
{
}
public static int cube(int num
{
return num
num
num;
}
What is the correct statement to pass value 8 to this method and assigns its return value to a variable named result?
O cube(8) = int result;
int result = cube(8)
O int result =
O int result = int cube(8);

- 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.
