Handling Java Exceptions

Java exceptions behave the same way in Clojure: they are JVM throwables. The syntax is just different.

1(try
2  (slurp "missing.txt")
3  (catch java.io.FileNotFoundException e
4    (throw (ex-info "File missing" {:path "missing.txt"} e))))

The Clojure pattern that Java developers usually learn next is ex-info + ex-data: wrap a failure with a message and a small data map that callers can inspect. This section focuses on writing exception handling that is explicit, testable, and not scattered across your core logic.
