(Java)​

Answer 1

Answer:

Hope you like the code !!!

Explanation:

import java.util.Scanner;

class Function

{

double a= 7.5;

double b= 3.2;

double c = 6.4;

void add()

{

double d = a+b+c;

System.out.println("The sum of numbers is : "+d);

}

void product()

{

double e = a*b*c;

System.out.println("The product of the numbers is "+e);

}

}

public class Main

{

public static void main (String [] args)

{

Scanner sc = new Scanner(System.in);

int val,f;

Function f1 = new Function();

System.out.println("Press 1 for 'Sum' & 2 for 'Product'");

val = sc.nextInt();

if (val==1)

f1.add();

else if(val==2)

f1.product();

}

}

Answer 2

Hey there!

The program is as follows:

class Fractionalno

{

public static void main(String args[])

{

doube a,b,c=0;

a = 7.5;

b = 3.2;

c = 6.4;

double s = a + b + c;

double p = a*b*c;

System.out.println("Sum =" + s);

System.out.println("product =" + p);

}

}

Sample Output:

Sum = 17.1

Product = 153.6
