Java ProcessBuilder.redirectError() is a method in the Java ProcessBuilder class that sets or retrieves the destination for the error output of a subprocess. This can redirect error messages to a file or merge them with standard output. Introduced in Java 1997 with Java 1.1, redirectError() is essential for managing and capturing error streams in external process execution.
