JFrame - Output and Input in Frame - menu choice and simple Calculator

[sambo731]

Okay so i have 2 Java files
Java Main Class - "Main.java"
and
Java Class - "frame.java"
these java files are in the same folder and project called "menuchoice"

Basically what i want to happen is have a JFrame window and have all the input and output code that comes with the calculator and menuchoice happen in the JFrame and not in the IDE NetBeans Run Window

Inside frame.java

// this is the frame set up java file

package menuchoice;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class frame extends JFrame{

    private JLabel item1;

    public frame(){
        super("The Title Bar");
        setLayout(new FlowLayout());

        item1 = new JLabel("This Is The Label");
        item1.setToolTipText("This Is Show On Hover");
        add(item1);
    }
}

Inside Main.java

// this is the file that contains the menu + calculator code.

package menuchoice;

import javax.swing.JFrame;
import java.util.Scanner;
public class Main {

  public static void main(String[] args) {

        frame oneframe = new frame();
        oneframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        oneframe.setSize(275,180);
        oneframe.setVisible(true);

        Scanner choice = new Scanner(System.in);{
            double menuselect;
            System.out.println("Please Enter the Number\n1. Addition\n2. Subtraction");
            menuselect = choice.nextDouble();
            if (menuselect == 1){
                Scanner addidtion = new Scanner(System.in);
                double fnum, snum, answer;
                System.out.println("Enter first number: ");
                fnum = addidtion.nextDouble();
                System.out.println("Enter second number: ");
                snum = addidtion.nextDouble();
                answer = fnum + snum;
                System.out.println(answer);
        }
            if (menuselect == 2){
                Scanner subtraction = new Scanner(System.in);
                double fnum, snum, answer;
                System.out.println("Enter first number: ");
                fnum = subtraction.nextDouble();
                System.out.println("Enter second number ");
                snum = subtraction.nextDouble();
                answer = fnum - snum;
                System.out.println(answer);}

            else{
                System.out.println("Error: Enter a valid menu choice");}
        }
        }

}

Picture of what currently is happening and what i would like to happen.

You really can't just move a console app to a GUI like you're trying to do. Well, you can, sort of, but it's ugly and kludgy. Part of the issue is that GUI applications don't just look different from console code, they are very different to the core since gui programs are event-driven while console programs are usually much more linear. What would be better is to read up on and learn how to create Swing apps from scratch, and you are interested, you should start here: Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

Much luck and welcome!
