Week 01 : Programming Assignment 1

Solution :


import java.util.Scanner;

public class W01_P1 {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int number = in.nextInt();

		// Check if the number is Positive or Negative and print accordingly
	    // Start
		if (number > 0) {
		  System.out.print("Positive");
		}
		else {
		  System.out.print("Negative");
		}
		// End

	in.close();
    }
}

Week 01 : Programming Assignment 2

Solution :


import java.util.Scanner;

public class W01_P2 {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        double radius = in.nextDouble();
        double height = in.nextDouble();

		// Calculate the volume
		// Start
		double volume = Math.PI * (radius * radius) * height;
		// End

	// Display the result
    System.out.printf("Volume is: %.2f", volume);
    in.close();
  }
}

Week 01 : Programming Assignment 3

Solution :


import java.util.Scanner;

public class W01_P3 {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int number = in.nextInt();

		// Print the multiplication table of number up to 5
		// Start
		for(int i =1; i < 5; i++) {
		  if (i != 4) {
		  System.out.println(number+" x "+i+" = "+(number * i));
		  }
		  else {
			System.out.print(number+" x "+i+" = "+(number * i));
		  }
		}
		// End

	in.close();
    }
}

Week 01 : Programming Assignment 4

Solution :


import java.util.Scanner;
public class W01_P4{
       public static void main(String[] args) {
	   Scanner sc = new Scanner(System.in);
	   int x=sc.nextInt();
	   int y=sc.nextInt();

		// code for quotient and remainder
		// Start
		int quotient = x / y;
		int remainder = x % y;
		System.out.println("The Quotient is = "+quotient);
		System.out.print("The Remainder is = "+remainder);
		// End

	sc.close();  
  }
}

Week 01 : Programming Assignment 5

Solution :


import java.util.Scanner;
public class W01_P5 { 
   public static void main(String[] strings) {
       double width ;
       double height;
       Scanner in = new Scanner(System.in);
       width = in.nextDouble();
       height = in.nextDouble();
		
		// Start
		// Calculate the perimeter of the rectangle
		double perimeter = 2 * (width + height);

		// Calculate the area of the rectangle
		double area = (width * height);
		// End

		// Print the calculated perimeter using placeholders for values
       System.out.printf("Perimeter is 2*(%.1f + %.1f) = %.2f\n", height, width, perimeter);

		// Print the calculated area using placeholders for values
       System.out.printf("Area is %.1f * %.1f = %.2f", width, height, area);    
   }
}
