IntelliJ

We will use IntelliJ on create Java program.

First Java program

Hello World
a+b
a+b with classes

Final code from classes

import java.util.Scanner;

public class Main {

    public static void main(String[] args)
    {
       Scanner in = new Scanner(System.in);

       System.out.println("Give me two numbers in separate lines:");

       number a = new number();
       a.setValue(Integer.parseInt(in.nextLine()));
       number b = new number();
       b.setValue(Integer.parseInt(in.nextLine()));
       
       number c = new number();
       c.setValue(a.getValue() + b.getValue());

       //int a = Integer.parseInt(in.nextLine());
       //int b = Integer.parseInt(in.nextLine());
       //int c = a+b;

       System.out.println(c.getValue());

       //System.out.println("Give me some String:");
       //String something = in.nextLine();
       //System.out.println(something);
    }
}

public class number
{
    private int value;

    public int getValue()
    {
        return value;
    }

    public void setValue(int x)
    {
        value = x;
    }
}
