изучайте JAVA язык

Несмотря на то что Java уже 20 лет, на сегодняшний день это один из самых мощных и революционных языков программирования, на котором пишут код более 9 миллионов разработчиков по всему миру. Практически повсеместно знание Java является одним из обязательных требований к соискателям на технические должности.
Java лежит в основе практически всех сетевых приложений. Появлением и быстрым распространением больших данных мы, по большому счету, также обязаны Java, интернет вещей без устройств на основе Java был бы невозможен. Современные учебные планы в области информационных технологий были бы неполными без курсов, посвященных объектно-ориентированному программированию и Java.
