throwable

Throwable is a term used in multiple domains with related but distinct meanings. In everyday language, a throwable is any object designed to be thrown by hand or by a mechanism, such as a ball or disc. The category is used in safety and handling contexts to distinguish throwables from items that are meant to be placed, launched remotely, or otherwise deployed. Throwables can range from simple sports equipment to improvised projectiles, and handling guidelines often emphasize safe distances, grip, and条件 for impact.

In military and civilian defense contexts, throwables refer to handheld munitions and deployable devices intended for short-range use. Examples include hand grenades, smoke grenades, and flare devices. These items typically incorporate safety features to prevent accidental discharge, a fuze or delay mechanism, and a designed fragmentation or dispersion pattern. Training and compliance standards address proper carry, release technique, and safe disposal to minimize risks to the thrower and bystanders.

In computing, Throwable denotes a base class or type that represents the collection of errors and exceptions that can be thrown during program execution. For example, in Java the class java.lang.Throwable is the superclass of all errors and exceptions; it has two main subclasses, Error and Exception, with RuntimeException being a common subclass of Exception. The throw keyword is used to raise a Throwable, which transfers control to an appropriate exception handler, typically via try-catch blocks. Different languages implement their own hierarchy and terminology, but the core idea is that a throwable represents something that can interrupt normal flow and be caught or handled.
