Question

Consider the getArea method from the textbook shown below.
Public int getArea()
{
If (width <= 0) { return 0; } // line #1
Else if (width == 1) { return 1; } // line #2
Else
{
Triangle smallerTriangle = new Triangle(width - 1); // line #3
Int smallerArea = smallerTriangle.getArea(); // line #4
Return smallerArea + width; // line #5
}
}
Where is/are the recursive call(s)?
A) line #1
B) line #2
C) lines #1 and #2
D) line #4

Quizplus · Accepted Answer

The recursive call in this method is in line #4, where it creates a new instance of the Triangle class with a width one less than the current width, and then calls the getArea method on that smaller triangle. This process repeats until the width is 1, at which point the recursion stops and the method returns 1. Therefore, the correct answer is D.
