OOP Overview (Constructors)
βββββββββ
In the following attached simple project java file called Employee we try to cover as much deep as possible about class, objects, functions, methods, assigning & initializing parameters, instantiate objects, accepting input from user and displaying (u can call it OOP overview buffae/α‘α) but our focus is on the following:
βοΈ Parameterized Constructor
βοΈ Non-Parameterized Constructor
βοΈ Overriding Constructors

Answer / Part 1 Explaining - OOP(Ex-1)
Understanding the scenario
βββββββββ
So before we start the coding process we must understand the problem, how Gregorianβs and Ethiopianβs Calendar π work, & how age calculating could be done.
β’Okey .... yβall just subtract date of birth from current dateπ easy right !
βBut, how it could be done, mean do we subtract all or each of values such as dates, months & years separately
βWhat if month of (date of birth) greater than current month / it becomes negative/
βIs each of years months or each of months days differs
YES, YES ....... Yes
π This is why we need logic and cases to solve low level problems upward to higher
>>start:
π£ </ Gregorian Calendar >
β’Each year has 12 months
β’Each months has different dates the highest is 31 and the lowest is 28
β’Leap year is February which is 2nd month 29 days and on non-leap year 28 days
π£ </ Ethiopian Calendar >
β’Each year has 13 months
β’Each 12 months has 30 days and the last one has 5 or 6 days
β’Leap year is Pagume/α·ααα which is 13th month 6 days & on non-leap year 5 days
ββββββ
π How to calculate Leap Years π
Pseudo Code (Gregorian)
If (year%4 = 0)
February = 29
else
February = 28
β’Which means if the year is divided by 4 without the remainder then February month has 29 days and the reverse/else which is false means it has 28 days.
Pseudo Code (Ethiopian)
If (year%4 = 3)
Pagume = 6
else
Pagume = 5
β’In the Ethiopian calendar leap is different only the reminder which the year divided by 4 is becomes only 3 then itβs leap year otherwise itβs not-leap year.
ββββββ
Note: declare months[] array with the following variables for months days in Gregorian calendar.
months[] ={31,February,31,30,31,30,31,31,30,31,30,31}
NB. February is a variable declared previously on leap year or not-leap year
ββββββ
There are two cases to deal with to calculate the age from date of birth (DOB)
βοΈ Case 1: subtracting without carry forwarded
Ex: Current: 2019.10.28
DOP: 1992.08.20
ββββββββ
Age : 27 years, 2 months, 8 days
βοΈ Case 1:
When we subtract from current date with carry forwarded from month or year
Ex: Current: 2019.10.28
DOP: 1992.12.30
ββββββββ
Age : 26, 8, 29
πSo to point the problem in this ππ½ example we cannot subtract 30 from 28 it will be come -2 this means there is no date called -2 but we can lend from the month, if we lend from month we must know how many days the month contains so we must check from the array we declared previously. But for the month we can borrow 12 or 13 months from year.
Pseudo Code (Case 1)
If (birthDate > curDate)
curMonth = curMonth - 1
curDate = curDate + months[curMonth]
If (birthMonth > curMonth)
curYear = curYear - 1
curMonth = curMonth +12
Pseudo Code (Case 2)
calcDate = curDate - birthDate
calcMonth = curMonth - birthMonth
calcYear = curYear - birthYear

The attached java file is age calculator in Ethiopian Calendar.
N.B: In this file we included some validation on current date, which validates if DOB(date of birth) year is greater than the current date year
i.e. DOB Year 2020
Current Year 2019
- Current Date is incorrect ! or
Student will born in the future?
N.B: And also on texts, such as singular to plural date numbers on outputs by adding βsβ letter.
i.e. If date is grater than 1 it will correct the word βday, month, yearβ to βdays, months, yearsβ respectively
- 20 years, 1 month, 3 days.
