public class Main {
public static void main(String[] args) {

    int almond = 8;
    Scanner apple = new Scanner(System.in);

// there is no difference apple int and almond. both are variables. the difference is that "Scanner" is a class.
}
}

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner apple = new Scanner(System.in);
// if you want to get INPUT from the user, we need to write (System.in)

}

}

THE USER WILL WRITE THE VALUE:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number");
int a = sc.nextInt();
}
}

_____________ IMPORTANT

-------------> For the user to get the results of the numbers they added, see below:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter two numbers separated by enter");
int a = sc.nextInt();
int b = sc.nextInt();
System.out.println("you entered two number and I plus them:"+(a+b));
}
}

now, to make it easier for user, you can make 2 different separate questions after each input. Example:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter first number");
int a = sc.nextInt();
System.out.println("Enter second number");
int b = sc.nextInt();
System.out.println("you entered two number and I plus them:"+(a+b));
}
}
// As you can see, theres a "sout" (system output print) before the "integer a" and before the "integer b". This way it becomes more user friendly and intuitive to use a certain program.

_______ Lets make a division

instead of defining a number to int, like 55, for example, you write the the users choice, which is unknown.

Example:

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter first number");
int apple = sc.nextInt();
System.out.println("Enter second number");
int almond = sc.nextInt();
System.out.println("You entered two numbers and I divided them:" +(apple/almond));
}
}

This was the Scanner Class. Next class is Java Operators and Arithmetics Examples.
