Consider the following class definition. public class Element
{
public static int max_value = 0;
private int value;
public Element (int v)
{
value = v;
if (value > max_value)
{
max_value = value;
}
}
}
The following code segment appears in a class other than Element.
for (int i = 0; i < 5; i++)
{
int k = (int) (Math. random() * 10 + 1);
if (k >= Element. max_value)
{
Element e = new Element(k);
}
}
Which of the following best describes the behavior of the code segment?
Exactly 5 Element objects are created.
Exactly 5 Element objects are created.
A. Exactly 10 Element objects are created.
B. Between 0 and 5 Element objects are created, and Element. max_value is increased only for the first object created.
C. Between 1 and 5 Element objects are created, and Element. max_value is increased for every object created.
D. Between 1 and 5 Element objects are created, and Element. max_value is increased for at least one object created.
E. The class Worker is defined below. The class includes the method getEarnings, which is intended to return the total amount earned by the worker.
public class Worker
{
private double hourlyRate;
private double hoursWorked;
private double earnings;
public Worker(double rate, double hours)
{
hourlyRate = rate;
hoursWorked = hours;
}
private void calculateEarnings()
{
double earnings = 0.0;
earnings += hourlyRate * hoursWorked;
}
public double getEarnings()
{
calculateEarnings();
return earnings;
}
}
The following code segment appears in a method in a class other than Worker. The code segment is intended to print the value 800.0, but instead prints a different value because of an error in the Worker class.
Worker bob = new Worker(20.0, 40.0);
System. out. println(bob. getEarnings());
Which of the following best explains why an incorrect value is printed?
A. The private variables hourlyRate and hoursWorked should have been declared public .
B. The private method calculateEarning should have been declared public.
C. The variable earnings in the calculateEarnings method is a local variable.
E. The variables hourlyRate and hoursWorked in the calculateEarnings method are local variables.
