Week 03 : Programming Assignment 1

Due on 2024-08-15, 23:59 IST

Create a class Department having a method getCourses that prints "These are the department's courses". It will have two subclasses, ComputerScience and MechanicalEngineering, each having a method with the same name that prints specific courses for the respective departments.Call the method by creating an object of each of the three classes.

(Remember to match the output given exactly, including the spaces and new lines)

(passed with presentation error means you will get full marks)

Select the Language for this assignment. 
File name for this program : 
class Department {
  public void getCourses() {
    System.out.println("These are the department's courses");
  }
}
// Create two subclasses, ComputerScience and MechanicalEngineering, each having a method with the same name getCourse() that prints specific courses for the respective departments.
class ComputerScience extends Department{
  public void getCourses() {
    System.out.println("Courses: Data Structures, Algorithms, Operating Systems");
  }
}
 
class MechanicalEngineering extends Department{
  public void getCourses() {
    System.out.println("Courses: Thermodynamics, Fluid Mechanics, Heat Transfer");
  }
}
class W03_P1 {

Week 03 : Programming Assignment 2

Due on 2024-08-15, 23:59 IST

There are two class cls1 and cls2 which is subclass of cls1.  cls1 having a method "add" which add two numbers. Create two method inside cls2 which will take 2 parameters as input i.e. a and b and print the sum , multiplication and sum of their squares i.e (a^2) + (b2).

(Remember to match the output given exactly, including the spaces and new lines)

(passed with presentation error means you will get full marks)

Select the Language for this assignment. 
File name for this program : 
import java.util.Scanner;
class cls1
{
    void add(int p,int q)
    {
        System.out.println(p+q);
    }
}
//Create subclass cls2 of cls1 which perform task of multiplication and sum of squares of passing two parameters.
class cls2 extends cls1{
  void mul(int p,int q)
    {
        System.out.println(p*q);
    }
  void task(int p,int q)
    {
        add(p*p,q*q);

Week 03 : Programming Assignment 3

Due on 2024-08-15, 23:59 IST

Write a program to print the factorial of a number by defining a recursive method named 'Factorial'.

Factorial of any number n is represented by n! and is equal to 1*2*3*....*(n-1)*n. E.g.-

4! = 1*2*3*4 = 24

3! = 3*2*1 = 6

2! = 2*1 = 2

Also,

1! = 1

0! = 0

Select the Language for this assignment. 
File name for this program : 
import java.util.Scanner;
class W03_P3{
//Create recursive method to find factorial of a number
 
static long factorial(int x){
  if(x == 0 || x == 1 )
    return 1;
  else 
    return x * factorial(x -1);
}
public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int x;
        x = in.nextInt();
        System.out.print(factorial(x));   
  }
}
