Java’s exception hierarchy is rooted in the Throwable class, with three primary categories: Checked Exceptions (Exception subclasses): Enforced by the compiler (e.g., IOException, SQLException). Represent recoverable errors (e.g., file not found, network issues). Require explicit handling via try-catch or propagation using throws.
