Chapter 6.7, Problem 6.21CP
Explanation of Solution
“Yes,” the overloaded methods should have different parameter lists and different return values.
Method overloading:
A special feature in Java which allows a class to two or more methods with the same name, but different signatures.
- The method signature may differ in number of arguments used or the type of arguments used or sometimes both.
Example:
Method signature with different parameter types, but same method name...

What exactly is method overloading? Is it OK to declare two methods with the same name but distinct argument types? Is it legal to declare two methods in a class with similar method names and argument lists but distinct return value types or modifiers?
Method Overloading is a feature that allows a class to have two or more methods having
same name, if their argument lists are different. Argument lists could differ in:
1. Number of parameters.
2. Data type of parameters.
3. Sequence of Data type of parameters.
Write different version of method sum() that display the sum of the values received as
parameter according to the following main method content:
public static void main(String[] args)
{
sum ( 10, 10 );
sum ( 10, 10, 10 );
sum ( 10.0, 10.0 );
sum ( 10, 10.0 );
sum ( 10.0, 10);
}
You have to define five functions with the specified types. Then, demonstrate the Argument
Promotion concept by reducing the number of method to two.

Random Number Guesser
Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit.
I have written a NumberGuesser class to make things easier.
// NumberGuesser.h
#ifndef NUMBERGUESSER_H
#define NUMBERGUESSER_H
#include <iostream>
class NumberGuesser
{
protected:
int low;
int originalLow;
int high;
int originalHigh;
public:
NumberGuesser(int l, int h) {
low = originalLow = l; high = originalHigh = h;
}
virtual int getCurrentGuess() {
return (high + low) / 2;
}
virtual void higher() {
low = getCurrentGuess() + 1;
}
virtual void lower() {
high = getCurrentGuess() - 1;
}
virtual void reset() {
low = originalLow; high = originalHigh;…
