Answer:
import java.util.Scanner;
public class homework_2
{
public static void main(String args[])
{
Scanner ab = new Scanner(System.in);
int a,b,c,d,f;
char e;
System.out.println("Enter your first number.");
a=ab.nextInt();
System.out.println("Enter your second number.");
b=ab.nextInt();
System.out.println("Enter your third number.");
c=ab.nextInt();
System.out.println("Enter your desired character.");
e=ab.next().charAt(0);
d= a+b+c;
f= a*b*c;
if(e == 's')
{
System.out.println("The sum of the entered numbers is " + d + ".");
}
else if(e == 'p')
{
System.out.println("The product of the entered numbers is " + f + ".");
}
else
{
System.out.println("Invalid character.");
}
}
}
Explanation:
This will be the answer.
Sum and Product.
- To check the given input we will use the if-else-if ladder.
- In if-else-if, we first check the condition and if it is false then we check another condition in the else-if clause.
- And further, we can add more else-if.
- The ladder ends with an else, which is not compulsory.
JAVA Code:
import java.util.Scanner;
public class sum_product {
public static void main(String agrs[]) {
double a, b, c, sum, prod;
char s, p;
Scanner sc = new Scanner(System.in);
System.out.println("Enter your choice (s or p):");
char ch = sc.nextLine().charAt(0);
if (ch=='s') {
System.out.println("Enter three numbers:");
a = sc.nextDouble();
b = sc.nextDouble();
c = sc.nextDouble();
sum = a + b + c;
System.out.println("Sum = "+sum+".");
}
else if(ch=='p') {
System.out.println("Enter three numbers:");
a = sc.nextDouble();
b = sc.nextDouble();
c = sc.nextDouble();
prod = a * b * c;
System.out.println("Product = "+prod+".");
}
else {
System.out.println("Invalid character");
}
}
}
