Java for beginners
Information can be placed in special "storage", and then use as many times as necessary. These storages are called modules.variables, and they help simplify the code and reduce unnecessary repetitions.
Functions - the bricks from which programmers build systems. Before you create your own functions, we will learn how to use existing ones and combine them.
Definition of functions
Logical operators and conditional instructions allow you to create programs that "make decisions" based on certain conditions.
Any code can be repeated tens, thousands, millions of times. And in combination with other tools we know — variables and conditions — this opens up many possibilities for building programs and complex systems.
