Java

I ran the calculator.java program on my laptop and on the Pocket PC. The output looks the same like this picture:

Which JVM did you use for the pocket PC? Pocket PC will typically use a J2ME JVM which could be provided by a third party, like Creme or IBM J9. Swing is not in the J2ME specification but some JVMs like Creme support it, which might be the reason why it works well on both, the laptop as well as pocket PC. However, if you write a program for a pocket PC, it is recommended that you use J2ME and one of the configurations/ profiles like CDC/ Personal Profile.

I used the Jeode compiler. The iPAQ came with the CD, so I installed the Jeode compile from the CD

Ok, it is in sync with the Personal Java 1.2 specification:

However that is EOL and you should look at migrating to CDC/ Personal Profile.

so that means...the program on pocket pc will be bigger size than on my laptop?

Mayank SAssociate Director - Product EngineeringCommented:
No it won't be.... you will just use a different compiler to compile it and a different JVM to run it than the one you are using on the laptop, because the laptop one will be based on J2SE whereas the pocket PC one will be based on some configuration/ profile of J2ME.
