    Question Running Java code on my mobile phone

    I have a Sony Erricson K700i. It runs Java. Can I write my own code and run it on my phone? If so, how? If not, why?

    If your phone has the JVM (as it apparently does) then it should be able to run any java bytecode, which is generated by the javac compiler (among others). You could also run C programs, or lots of other languages if you feel like it . . . .

    I think you can get a Symbian (OS used in Nokia and Ericsson) compiler from there:

    I don't think my model uses symbian.

    Then you should find out what OS your model is using.

    OFFTOPIC: Siavoshkc, I can't use your code painter, because I don't have .NET framework and I can't install it (my windows update is messed up)

    You don't need to do so. Just download from my link and install the program.

    How hard is that to understand?
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    >> My problem is I have never programed in Java.

    I wonder if a jboard.jprogramming.com exists ... or it would have a sun in it somewhere wouldn't it?

    I feel for you. But have you by this time realized that you can look for java tutorials on google, just like you could have looked for your cellphone characteristics before posting in here?

    Or are you going to do again one of those "if yes, how. if not, why" type of questions?

    I didn't know where to begin. I didn't know Sony-Ericsson has a special developer center. The only thing I knew was that it runs Java because of its logo on the phone screen. I thought someone here may have some exprience on writing code for cell phones.

    I hopelessly went to Sony-Ericsson site to find the device's OS. It was so good if I could write C/C++ code for it instead of Java as it is possible for simbian OS. But unfotunately it is impossible. Fortunately SE site has all the documentation needed, but at the mean time I don't have enough time to begin learning Java.
