Question

Ok im having a problem trying to use a for loop in the static add method to obtain the sum of the even numbers between two end points, and return the sum to the main method

Answer 1

my code is:

import java.util.Scanner;

public class Calculate {



public static void main(String[] args) {

Scanner keyboard = new Scanner(System.in);

int num1, num2;

System.out.print("Enter two integers: ");
num1 = keyboard.nextInt();
num2 = keyboard.nextInt();

String input;
System.out.println("Enter a string: ");
input = keyboard.next();



if(input.equals("add"))
{
while(num1%2==0 && num1<num2)
{
int sum;
sum = add(num1, num2);
System.out.print("The sum of two integers is: " + sum);
System.exit(0);
}
}
else if(input.equals("multiply"))
{
int product;
product = multiply(num1, num2);
System.out.print("The product of two integers is: " + product);
}
else
{
System.out.println("Error, invalid input!");
}



}
public static int add(int number1, int number2)
{

int result;
result = number1 + number2;
return result;
}
public static int multiply(int number1, int number2)
{
int result;
result = number1 * number2;
return result;
}

}
