What is Java?
Java is an object oriented programming language developed by Sun Microsystems in early 1990 by developers James Gosling, Mike Sheridan and Patrick Naughton.
In 1991 James Gosling and his friends formed a team called Green Team to further work on this project. The original idea was to develop this programming language for digital devices such as television, set-top box, remote etc. Later this idea was dropped and Java is developed for internet programming.
Why learn Java?
Java Programming language has several features which other programming languages don’t have. Java receives updates regularly which makes it more robust and future proof. Lots of new features are added on every Java release. There are several features of Java, some of them are:
- Platform independent: Java doesn’t depend on the operating system. For example, a program written on Mac OS can run on Windows and vice versa.
- Easy to learn: Syntax is easy and there are lot of tutorials available online including the one which you are currently reading.
- Performance: Java is significantly faster than other traditional interpreted programming languages. Compiled java code which is known as byte code is like a machine code, that allows a faster execution. Java uses Just in Time compiler which can execute the code on demand, this allows to execute only the method that is being called, which makes it faster and efficient.

Здесь мы описали шаблон будущего объекта – класс. У него есть две переменные состояния – speed и maxSpeed, а также две функции, которые описывают поведение объекта.
Теперь приложение нужно запустить, для этого Java надо подсказать, где находится точка входа в него. Для этого существует особое соглашение – нужно добавить в описание любого объекта метод:
Наше приложение запустилось, но ничего не произошло, потому что мы не добавили никакой логики в метод. Добавим простой вывод на консоль текста:
Создатели предложили называть эти папки как доменные имена в интернете, чтобы точно разграничить их, но это не обязательно, вы можете называть их как захотите.
Это так же позволяет легко импортировать чужие классы в свой код:
