Date Program ISC Computer Science 2020 Theory

-

Design a class Convert to find the date and the month from a given day number for a particular year.

Example: If day number is 64 and the year is 2020, then the corresponding date would be:
March 4, 2020 i.e. (31 + 29 + 4 = 64)

Some of the members of the class are given below:

Class name: Convert
Data members/instance variables:
n: integer to store the day number
d: integer to store the day of the month (date)
m: integer to store the month
y: integer to store the year
Methods/Member functions:
Convert(): constructor to initialize the data members with legal initial values
void accept(): to accept the day number and the year
void dayToDate(): converts the day number to its corresponding date for a particular year and stores the date in 'd' and the month in 'm'
void display(): displays the month name, date and year

Specify the class Convert giving details of the constructor, void accept(), void dayToDate() and void display(). Define a main() function to create an object and call the functions accordingly to enable the task.

import java.util.Scanner;
class Convert{
    int n;
    int d;
    int m;
    int y;
    public Convert(){
        n = 0;
        d = 0;
        m = 0;
        y = 0;
    }
    public void accept(){
        Scanner in = new Scanner(System.in);
        System.out.print("Day number: ");
        n = Integer.parseInt(in.nextLine());
        System.out.print("Year: ");
        y = Integer.parseInt(in.nextLine());
    }
    public void dayToDate(){
        boolean isLeap = false;
        if((y % 4 == 0 && y % 100 != 0) || y % 400 == 0)
            isLeap = true;
        int dm[] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
        if(isLeap)
            dm[2] = 29;
        int i = 1;
        while(n > dm[i]){
            n -= dm[i];
            i++;
        }
        d = n;
        m = i;
    }
    public void display(){
        String mn[] = {"", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
        System.out.println(mn[m] + " " + d + ", " + y);
    }
    public static void main(String args[]){
        Convert obj = new Convert();
        obj.accept();
        obj.dayToDate();
        obj.display();
    }
}

A class Encrypt has been defined to replace only the vowels in a word by the next corresponding vowel and forms a new word, i.e. A → E, E  → I, I  → O, O  → U and U  → A. Example : Input: COMPUTER Output: CUMPATIR Some of the members of the class are given below: Class name : Encrypt Data members/instance variables : wrd: to store a word len: integer to store the length of the word newWrd: to store the encrypted word Methods/Member functions : Encrypt(): default constructor to initialize data members with legal initial values void acceptWord(): to accept a word in uppercase void freqVowCon(): finds the frequency of the vowels void nextVowel(): replaces only the vowels from the word stored in 'wrd' by the next corresponding vowel and assigns it to 'newWrd', with the remaining alphabets unchanged void disp(): displays the original word along with the encrypted word Specify the class Encrypt giving details of the constructor, void acceptWord(), void freqVowCon(), void ...

Design a class NoRepeat which checks whether a word has no repeated alphabets in it. Example : COMPUTER has no repeated alphabets but SCIENCE has repeated alphabets. The details of the class are given below: Class name : NoRepeat Data members/instance variables : word: to store the word len: to store the length of the word Methods/Member functions : NoRepeat(String wd): parameterized constructor to initialize word = wd boolean check(): checks whether a word has no repeated alphabets and returns true else returns false void prn(): displays the word along with an appropriate message Specify the class NoRepeat, giving details of the constructor, boolean check() and void prn(). Define the main() function to create an object and call the functions accordingly to enable the task. import java.util.Scanner; class NoRepeat{     String word;     int len;     public NoRepeat(String wd){         word = wd;         len = word.le...

A super class Bank has been defined to store the details of the customer in a bank. Define a subclass Interest to calculate the compound interest. The details of the members of both the classes are given below: Class name : Bank Data members/instance variables : name: to store the name of the customer accNo: integer to store the account number principal: to store the principal amount in decimals Methods/member functions : Bank(...): parameterized constructor to assign values to the data members void display(): to display the customer details Class name : Interest Data members/instance variables : rate: to store the interest rate in decimals time: to store the time period in decimals Methods/member functions : Interest(...): parameterized constructor to assign values to the data members of both the classes double calculate(): to calculate and return the compound interest using the formula: CI = P(1 + R / 100) N - P, where P is the principal, R is the rate and N is the time void displ...
