How do i get my none programmer friends to try out my simple programs by just clicking on them?

Hello. So my friends are asking me to show them some of the little programs i have been developing, and i would love to just send it as an email attachment so they can just click on it and it automatically loads up. But at the moment the only way i know to run my programs is by using an IDE or the command line and if they were to use the command line i would have to explain to them about how to set the classpath and tell them to type in things like cd C:\ java.

So obviously when people write programs the user does not have to go through all that. They should be able to just click on the file and it loads up. ( I know they would need to have java on their computer though).

I have only just started learning about GUIs and am at the stage of learning to add buttons and learning about Action Listeners and such. But i've been flicking ahead though my books and i can't find any mention of how i can get others to use my programs.

So is there a way to do this? If so can you write a link to an article explaining how, or even just a term that i can search in google.

Thanks to anyone who takes the time to help.

The term you want to search for is 'Executable JAR'.

A JAR is a Java ARchive, very much like a ZIP file, but with a special manifest (text file) which tells Java where the main class is. A good IDE will have a wizard for making a JAR file (or it can be done using the command line). The JAR has to contain all of the classes for the app. The user downloads the JAR, double clicks it, and the app runs (as long as they have Java properly installed). Do a quick search and you will find lots of help on how to build them.

To add to what Steve has told you: look in the Java™ Tutorials section.

Thank you! That's all i needed to know. :)

Cheers i'll read that now.

You're welcome

Hello i've been trying to make a jar file and something seems to be going wrong.

This is an article with the instructions i have been following Creating an Executable jar File
The error i'm getting when i try to run the jar file is "Could not find the main class: TurtleTest3 . Program will exit."

I have 3 classes in my program the one with the main method is called "TurtleTest3" and the other two are called "Turtle3" and "Instructions".

These are the exact steps i have taken. I am using command prompt.

echo Main-Class: TurtleTest3 >manifest.txt

(then i push enter)

jar cvfm TurtleGame.jar manifest.txt TurtleTest3.class Turtle3.class Instructions.class

(then i push enter and it displays a load of info)

TurtleGame.jar

(then it displays the error message i told you about)

Anyone know what i'm doing wrong?

Please don't post a new and fresh question on an old thread. Closing thread.
