About this event

[T226 Week 6 & 8]

The KOISS Coding Club invites KOI IT students to participate in the Java CodeLab Challenge, a two-session coding event designed to develop practical Java programming, debugging, logical thinking and problem-solving skills.

Delivered through HackerRank, the event gives students an opportunity to practise solving programming problems in a structured and competitive environment, while developing skills that can be valuable for technical interviews and future careers in IT.
