I want to export this program as a single runnable file to email to a friend. How would you go about doing this?

Code:

import java.util.Scanner;

public class Addition {

public static void main(String[] args) {
System.out.println("Welcome To The Addition Calculator");
System.out.println("Please Type The First Number:");
Scanner scan = new Scanner(System.in);
double num1 = scan.nextDouble();
System.out.println("Please Type The Second Number:");
double num2 = scan.nextDouble();
double num3 = num1 + num2; //you could use int instead of double
System.out.println("The Anwser Is: " + num3);
}

}

Select File -> Export. In the Export dialog select Java -> JAR file, then you need to specify the JAR file name and main class.

I did that and even tried the runnable jar file and when i double clicked it, it wouldn't do anything. I know if you have the java jdk installed then you can go into command prompt, goto the directory of the .jar file and type "java (tthen the name of the file w/o .jar)" but I just want it to be double clicked. any other way?

Thanks, Zach

So the problem is the association of file type JAR in your OS. The *.jar file does not associate to Java launcher, check file type association on your computer.
