How to add User Inputs?

Question

Well I'm new to Java, and I was trying to make a basic calculator to add 2 user inputs and give a total. Here is my code:
import java.util.Scanner;
public class calculator {
     public static void main(String[] args) {
          int total;
          Scanner number1 = new Scanner(System.in);
          Scanner number2 = new Scanner(System.in);
          System.out.print("Enter your first number: ");
          System.out.println(number1.nextLine());
          System.out.print("Enter your second number: ");
          System.out.println(number2.nextLine());
          total = number1 + number2;
          System.out.print("Your total is: " + total);
}And here is my error:
C:\Users\Jennifer\Desktop\Vincent's Things>javac calculator.java
calculator.java:13: operator + cannot be applied to java.util.Scanner,java.util.
Scanner
                total = number1 + number2;
                                ^
1 errorI tried giving it a cast, since it's saying Scanner's can't be operated, such as:
          total = (int)number1 + (int)number2;But that didn't work. How can I make it so it adds the two inputs?

Answer 1

A Scanner is a Scanner. Of course you can't just add two Scanners together. The Scanner could also be used to read text. A Scanner can't read your mind to know what type of data you are reading. You have to tell the Scanner what type of data you are reading. They way you do that is to read the Scanner API and use the proper methods.
