Answer:
Here is the constructor:
public Square(double s)
{ //constructor name is same as class name
sideLength = s; } //s copied into sideLength field
Explanation:
The above constructor is a parameterized constructor which takes a double type variable s as argument. The name of constructor is same as the name of class.This constructor requires one parameters. This means that all declarations of Square objects must pass one argument to the Square() constructor as constructor Square() is called based on the number and types of the arguments passed and the argument passed should be one and of type double.
Here is where the constructor fits:
public class Square {
private double sideLength;
public Square(double s)
{
sideLength = s; }
public double getArea() {
return sideLength * sideLength;}
public double getSideLength() {
return sideLength; } }

Explanation:
Heap sort pick an item from the first or last position in an array and compares it with other items in other positions in the array, swapping position if they meet the condition.
The array above has three maximum items arranged sequentially in the array, this is prove that there have been 3 reheapifications in the array.
