Ev'ning,

no problems solving it, but since my JavaVM stopped because of a stack overflow, when I tried to run the code, I had to port it to C...
I'm wondering, whether there is any option to increase the default stack-size in java?

what about 'java -X'? Then you can use 'java -Xss1024M' for 1Gb stack size...
But do you really need it?

Ah, thanks!
I don't work with Java normally, since I don't like bytecode,
so I didn't know any parameters..

But do you really need it?

Well, not any more, since I've done that challenge,
but we're hacking to learn, aren't we?
And next time I need to run some heavy recursive java code,
I'll know how to increase the stacksize

I get the same problems with the Stackoverflow.
Then I turned the recursive function into an iterative one.
It works fine.

I think donster's post is giving to much hint on solving the challenge. Maybe the post should be censored.

this discussion is a little to give-away, but since the problem is really quite simple i'm not going to worry about it.

I changed the code to vb and used another method to count up

However the result i get seems to be wrong...
My result is a 5 digit number, does that sound alright?

Uhm, since I don't even know the words recursive or iterative (should I? I'm 16), yes.

Hello,

i have a problem with the upcount challenge. I installed jdk 1.6.0_17 and compiled the class file without any problems but when i run the classfile i got an exception:

Exception in thread "main" java.lang.NoClassDefFoundError: upcount/class
Could not find the main class: upcount.class. Program will exit.

I really dont understand that because i changed nothing in the upcount.java file.

I hope the text above is not a spoiler...

thx in advance(?)

Sandy

What are you using to run it?

the simple commandline tool in the jdk named java

How so? You might be doing something wrong.

the classfile from the upcount.jave is in the same directory like java and so i just type in

java upcount.class

then the error appears

When running a Java application from the command line you don't want to append the .class extension. Just the class name. So in your case it would be something like

oh youre right! Thx! What a dumb failure
