Books by Peter Spath

Peter Spath consults, trains/teaches, and writes books on various subjects, with a primary focus on software development. With a wealth of experience in Java-related languages, the release of Kotlin for building Android apps made him enthusiastic about writing books for Kotlin development in the Android environment. He also graduated in 2002 as a physicist and soon afterward became an IT consultant, mainly for Java-related projects.
