Java Console In Eclipse, But What If Using As Jar?

Question

So,

I have made a little game in eclipse, it generates a rondom number from 1 - 1000 , when playing out of Eclipse, it plays in the eclipse console, but what if i want to play it without eclipse? There is no console showing up? Anyone a idea on how to fix this? EDIT : I would like a new GUI instead of CMD.

Grts PS: Tell me if you need a specific part of the source code

No need to show code. Use your OS command line to execute the jar. — Luiggi Mendoza, Aug 18 '12 at 16:38

Its not a diplicate, i would like to use a new GUI for it, instead of CMD — Joppe De Cuyper, Aug 18 '12 at 16:43
I'm not sure what you mean by "a new GUI." `java` executes from the command line, `javaw` executes in a window. — Tony R, Aug 18 '12 at 16:45
[this](http://www.java.com/en/download/help/javaconsole.xml) might be related... Haven't used it but maybe it will force show a console window for windowed applications? — Tony R, Aug 18 '12 at 16:48
In other words, you would like to execute the jar as an exe? — Luiggi Mendoza, Aug 18 '12 at 16:52
Not really a EXE, but a new window appears that works like CMD, but isnt CMD, because CMD looks bad for a game — Joppe De Cuyper, Aug 18 '12 at 16:55
@Joppe Dnb Cuyper - Sounds like maybe you want to learn about JTextArea ;) — paulsm4, Aug 18 '12 at 21:42

1) You should probably export your program as a .jar file.

This isn't absolutely necessary - but it's better. And it sounds like you've already done it :)

2) Be sure to specify the main class in Eclipse before you export the .jar

3) Once you have the .jar, you can:

   a) execute "java -jar myjar.jar" from a command prompt (for a console-mode program)    
   b) execute "javaw2 -jar myjar.jar" from a command prompt (for a Swing/GUI program)

4) You can also set a "file association" with javaw in Windows so that you can just double-click on the .jar to execute it:

You want a GUI, that's what "javaw" is for. You don't want to type "javaw" in a command prompt, that's what a file association is for. Or, for that matter, a .bat file and/or desktop shortcut are other options. You want it, you got it ;) Simple as that :) – paulsm4 Aug 18 '12 at 16:57

If you want a GUI, you will have to develop one yourself. There is no "Java Console GUI" that I've ever heard of.

My game uses a GUI, where you can click Start but it will still open as a CMD – Joppe De Cuyper Aug 18 '12 at 16:57
Where do you "click Start?" If you already have a GUI, see @paulsm4's answer. – Dave Aug 18 '12 at 17:00

It seems the OP wants to reroute console output to a location of his choosing, not open an actual shell.

Here is one way to reroute stdout.

You can send it to a string, stream, file, etc. and then print it yourself into a window.
