There’s a basic structural and foundational unit of everything that exists. The basic unit of matter is an atomEven though there are subatomic particles, they don’t act as a functional unit for matter. The basic unit of living beings is a cellEven though there are subcellular elements, they don’t act as a functional unit for life. As far as this course is concerned, the foundational unit of a computer program is known as a method. As its name implies, there’s a method to executing any specific task. Creating correct steps in each method, and arranging the right order of methods, provides for a modular and organized approach to constructing and maintaining code. As we delve into this course, understanding the significance of methods will be key to mastering the art of procedural programmingThis involves breaking down a program into smaller, reusable procedures to execute tasks sequentially. in Java.

A method has three components: input, processing, and output.
