henryobinna:
ever since I posted that error here no body ever cared to give a suggestion or probably the cause.

I know this is ages ago, but I just stumbled on the post and decided to reply, as no answer been given.
From the error message:

henryobinna:

Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = '2'
at GradeBook.displayGradeReport(GradeBook.java:82)
at GradeBookTest.main(GradeBookTest.java:7)

In the GradeBook.displayGradeReport method, change the line:
System.out.printf("class average is %2.f\n", average);
to
System.out.printf("class average is %.2f\n", average);

Java Formatter uses "%.2f" to represent a 'float' variable, but you used "%2.f" which threw the UnknownFormatConversionException

That book was my first Java ebook and I really enjoyed it. Lemme know if you need any other Java help.

HELP ME.

it seems you're trying to access the paid features of aide, which requires Internet access and your visa/MasterCard.

simply press back, swipe the left of your screen and tap "code for experts" to continue. coding

SUGARSON:
@PREBOY, THAT'S FOR EXPERTS. I'M JUST A BEGINNER, I DON'T KNOW HOW TO CODE YET.

I thought you've been using it

anyway, go to settings/app on your Android, locate aide then clear data... it should reset the app

SUGARSON:
@PREBOY, IF IT RESETS WHAT WILL HAPPEN? WILL IT REMOVE THE RESTRICTIONS?

if you mean the restrictions on the tutorials, then i'm sorry bt it can't, you'll have to purchase those

Yo, get any of the luckypatcher versions of 5.5.+ they have two patches for A.I.D.E. try each till one will work.

note: need to be rooted and have busybox installed fully.

@preboy or any other expert can I use QPython for Web,game or App development if so kindly put me through

i don't know for sure, i own a PC now so i don't use my android for programming anymore.... you should check their documentation page to find out which python library Qpython currently supports and if they can suit your needs

i do know it supports web2py, django and some other web frameworks dunno abt app development

check here= http://qpython.com/ http://pypi.qpython.org/index.php/qpython-libraries/
