We Want to Create a Class That Represents a Geometric

question 92

Multiple Choice

We want to create a class that represents a geometric sequence. A geometric sequence is a sequence of numbers that begin at some value and then multiplies each value by some constant to get the next value. For example, the geometric sequence 1, 2, 4, 8, 16 starts at 1 and multiplies each term by 2 to get the next. The geometric sequence 10.8, 5.4, 2.7, 1.35 starts at 10.8 and multiplies each term by 0.5 to get the next. The basic framework of a geometric sequence class is below: public class GeometricSequence
{
Private double initialValue;
Private double multiplier;
}
We want to produce elements of the geometric sequence using code like:
System.out.println (first.next() ) ; // Prints 1 and advances
System.out.println (first.next() ) ; // Prints 2 and advances
System.out.println (first.next() ) ; // Prints 4 and advances
System.out.println (first.next() ) ; // Prints 8 and advances
System.out.println (second.next() ) ; //Prints 10.8 and advances
System.out.println (second.next() ) ; //Prints 5.4 and advances
System.out.println (second.next() ) ; //Prints 2.7 and advances
Which of the method specifications below will allow this code to behave as desired?

• A) public next() : double
• B) public int next()
• C) public void next(double result)
• D) public double next()
