Need help [Not sure what to make as title for this...]

[Pretender]

Hey there everyone!
I'm not going to go too in-detail at the start, read my introduction for prior knowledge of me and my experience.

I was just wondering, I am using Eclipse at the moment. Once I have created all my classes, how do I compile to a jar?

After this, how do I upload it to a website to be shown?
Thanks,

Pretender.

P.S - I am not great at Java... I would just like to learn to upload them for future knowledge.

import java.util.Scanner;

class apples{
	public static void main(String args[]){
		Scanner input = new Scanner(System.in);
		double fnum, snum, ans;
		System.out.println("Enter your first number: ");
		fnum = input.nextDouble();
		System.out.println("Enter your second number: ");
		snum = input.nextDouble();
		System.out.println("Here is your answer: ");
		ans = fnum + snum;
		System.out.println(ans);
	}
}

I haven't learned how to make the actual applet yet, like the border it goes in. But, how would I upload this to a website?

Your code is not an applet, it looks like a application because of the main() method and it does not extend the applet class.
Have you read the tutorial about applets?
