Students in the Coding Club at Alexander Hamilton High School are sharpening their Java and Python skills in preparation for two programming competitions at the end of March.

Earning this certificate helps Java developers increase the security of their software and reduce vulnerabilities in the programs they develop.

According to a recent Coding Dojo analysis, Java was one of the top two most in-demand programming languages in 10 major U.S. cities -- highlighting the need for a full-stack Java developer course.
