Part A:
We want to create a class that represents a geometric sequence. A geometric sequence is a sequence of numbers that begin at some value and then multiplies each value by some constant to get the next value. For example, the geometric sequence 1, 2, 4, 8, 16 starts at 1 and multiplies each term by 2 to get the next. The geometric sequence 10.8, 5.4, 2.7, 1.35 starts at 10.8 and multiplies each term by 0.5 to get the next. The basic framework of a geometric sequence class is below:
public class GeometricSequence {
private double currentValue;
private double multiplier;
}Assume that the parameters to the constructor are initialand mult. What should the body of the constructor be?
double currentValue = initial;
double multiplier = mult;
initial = currentValue;
mult = multiplier;
double initial = currentValue;
double mult = multiplier;
currentValue = initial;
multiplier = mult;

Part B:
We want to create a class that represents a date. A date has a day, month, and year. For example, the date March 16, 2014 has the day 16, month 3, and year 2014. The parameter variables in the constructor for month, day, and year should be m, d and y. The basic framework of a date class is below:public class Date {
private int day;
private int month;
private int year;
}
What should the body of the constructor be?
day = 1;
month = 1;
year = 1990;
int day = d;
int month = m;
int year = y;
d = day;
m = month;
y = year;
day = d;
month = m;
year = y;

A public class in Java is an object blueprint that details the properties and methods of objects that fall under that class.  

What is Public Class?

  • An access modifier is a Java public keyword. It can be applied to classes, constructors, methods, and variables. It is the type of access modifier that is least constrained.
  • Everywhere has access to the public access modifier. As a result, we have easy access to both the class and package's public.
  • Any method that is being overridden must not be more restrictive than the original method, which must be stated in the subclass. Therefore, if you give a method or variable the public access modifier, only the public access modifier can be used to override it in a subclass.
  • A programme may only designate one class as public if it has many classes.
  • The name of the programme must be similar to the name of the public class if a class contains one.
