What are events and methods in programming?

Answer 1

There are two major categories of programs which utilize event-driven method of their implementation: device drivers and GUI programs. Both spend most of their life cycle in waiting loop and perform any action only upon an incoming event, such as hardware interrupt, or an user's action. Internally, an incoming event may be processed by receiving code or dispatched to further code layers.

Answer 2

System events and user events

System events is like the clock on the PC changing automatically and windows update etc.

User events is stuff like the colour theme being personalised and desktop background etc.

Answer 3

A method is similar to a function (also known as a procedure or subroutine, depending on the language). The main feature of a method is that it is defined within a specific class; therefore, the method will normally work with objects of that class.

An event is something that happens, and that can affect the program, usually from outside the program: for example a keypress or a mouse click. The term event is also used for the computer code (the method) that reacts to such as event.
