Money Object Passing Program in Java

 /**
   Money is an unit that has 2 parts, Rupees and Paise, where 100 Paise=1 Rupee.
Design a  class named Money whose details are as follows:
Class Name : Money
Data member:
int rs, ps  : integer to store the value of Rupees and paise.
Member methods:
Money(…..)     : parameterized constructor to initialize member data
void fnShow()  : to show the member data as Money [Rs 819.75]
Money fnAdd(Money m1, Money m2) :
Add m1 and m2. Store the result in corresponding member data and return it.
Specify the class Money, giving the details of the above member data and methods. 
Also write the main() to create objects and call the other methods accordingly to 
enable the task of the adding 2 units on Money.

ISC Program: Predict day of the week from date

Algorithm : 1)Take the last two digits of the year. 2)Divide by 4, discarding any fraction. 3)Add the day of the month. 4)Add the month's key value: JFM AMJ JAS OND 144 025 036 146 5)Subtract 1 for January or February of a leap year. 6)For a Gregorian date, add 0 for 1900's, 6 for 2000's, 4 for 1700's, 2 for 1800's; for other years, add or subtract multiples of 400. 7)For a Julian date, add 1 for 1700's, and 1 for every additional century you go back. 8)Add the last two digits of the year. 9)Divide by 7 and take the remainder. Example : Let's take a date: 26/03/2027 Last two digit of the year = 27 Divide by 4 discard fraction = 27/4 = 6.75 = 6 Add day = 6 + 26 = 32 Month key = 4 + 32 = 36 Add year code = 36 + 6 = 42 Now add two digits of the first year = 42 + 27 = 69 Now get the remainder after dividing by 7 = 69%7=6 So 1 is Sunday so 6 is Friday So 27/03/2027 Program : import java.util.Scanner; public class daydate {     public static void main(String[] arg...
