So I am working on a project and my code works when I put a float or int in the first input and then add with an int in second input. But if I try to add a int in the first input and a float in the second input it does not work.
For example,
Enter the first number:
34.6
This input is of type float.
Enter the second number:
90
Your answer is: 124.6
The above works.
Below does not work.
Enter the first number:
90
Enter the second number:
34.7
Here is my code:
import java.util.Scanner;
// Basic Intro/ Refresher for Sums using User Input
public class BasicSums {
public static void main(String[] args) {
// User input
Scanner input = new Scanner (System.in);
System.out.println("Enter the first number: ");
if (input.hasNextInt()) {
int initial = input.nextInt();
System.out.println("\nEnter the second number: ");
int second = input.nextInt();
System.out.println("Your answer is: " + Integer.sum(initial, second));
//Considering the possibility of the user entering a decimal value
} else if (input.hasNextFloat()) {
System.out.println("This input is of type float.\n");
float first = input.nextFloat();
System.out.println("Enter the second number: ");
float second = input.nextFloat();
System.out.println("Your answer is: " + Float.sum(first, second));
}
}
}
>Solution :
In the if block for if (input.hasNextInt()) (i.e. the first input is an integer), you only try to read two ints (using input.nextInt()), so inputs with decimals will not be accepted for the second number.
One way to fix this is to use float second = input.nextFloat(); and just use the + operator to sum first and second.
Since integers can be considered real numbers with no fractional part, you can also simply read two floats (or doubles, for higher precision) and add them with the + operator.
