ඉක්මණින්ම ST II Assignment ගොඩ දාගන්නත් එපැයිනේ - Part 8

ඉක්මනින්ම iReport වැඩෙත් ඉවර කරලා දාමු.
iReport වලින් report එකක් design කරලා, parameters සෙට් කරලා,
NetBeans වල ඉදන් ඒ iReport file එකට, load කරන හැටි.

සැ.යු. - Interface Design එක ගැන සලකා නැත. මුලිකම පෙනුම පමණි.
එක් එක් coding කුමක් සඳහාද යන්න තේරුම් ගැනීම ඔබ සතුය.
