Question
(i) Identify the TWO (2) syntax errors found in Figure 2.
(ii) Demonstrate how you would modify the Circle1 class and also the TestCircle1 driver class to allow flexibility at the users’ point of view and at the same time, to achieve the benefit of encapsulation. Write snippet of codes to illustrate your answer.

Refer to the Circlel class implementation shown in Figure 1 below.
public class Circlel {
private double radius;
Circlel () {
radius = 1.0;
double getArea () {
return Math.PI * radius * radius;
Figure 1
Also, given that the driver class has been implemented as shown in Figure 2 below.
public class TestCirclel l
public static void main (String[] args) {
Line 1
Line 2
Line 3
// Create a circle with radius 3.5
Circlel yourCircle = new Circlel (3.5);
System.out.println ("The area of the circle of radius "
+ yourcircle.radius + " is " + yourcircle.getArea ());
Line 4
Line 5
Line 6
Line 7
Line 8
// Modify circle radius
yourcircle.radius = 100;
System.out.println ("The area of the circle of radius "
+ yourCircle.radius + " is " + yourCircle.getArea ()) ;
Line 9
Line 10
Line 11
Line 12
Line 13
Line 14 }
Figure 2
Before you can even execute the TestCirclel driver class, you noticed that there are syntax
errors issued by the compiler.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fedf5812b-3f46-44c3-9c3a-b2a8aab11ea9%2Fecf4a931-3a89-4b44-9706-c631c06e15b4%2F2cq9m8a_processed.png&w=3840&q=75)
