[yenna 0]

APA KABER SEMUA....BOLEH BANTU SAYA DENGAN CODING NI TAK...

SAYA NAK BUAT CODING UNTUK SEARCH DAN DELETE DLM CLASS...CODING UNTUK ADD DAN DISPLAY DAH OKEY CUMA NAK BUAT SERACH N DELETE JER TAK DER IDEA LA....

BOLEH SAPA-SAPA TOLONG TAK....TERIMA KASIH

KAT CN KITER BAGI ONE PART OF THE CODING TU FOR REFERENCE::
