coding in java

[speX]

ok.. i know how to code in java... but i was wondering how do i install the java sdk for fedora core 4.... so that i can compile and also.. wats a good text editor to use? that can compile inside the text editor (like crimson editor) i used crimson editor but i wana try something a little more advance...

Download the Linux RPM version of the J2SE JDK from java.sun.com and install it using 'rpm -ivh <rpm file>'. They distribute the package through a ".rpm.bin" file (to display license stuff), so run 'sh <bin file>' to extract the RPM.

 

For the editor - depends on what you want. I like SciTE. It's a small and lightweight editor that can compile. If you're looking for an IDE check the Eclipse project.

ok so i got SciTE working.. it compiled my code and ran it.. i saw the first screen of my program but when it was suppose to have user input it goes

"Error: your input doesn't represent a valid integer value"

 

why is that?

[z0ny]

Err, I assume that your program has a bug. :)

Or don't you see the error when compiling and starting directly from the shell? o_O

[speX]

theres no error in my code for sure cause my program ran fine in windows..... so.... ya

[z0ny]

Second question unanswered. ;)
