Przedstawiono praktyczne aspekty programowania w języku Java. Zbadano możliwości zwiększenia wydajności programu w Javie w obrębie zarządzania zasobami. Przeprowadzono pomiary czasu wykonania programu dla operacji strumieniowych w zakresie odczytu i zapisu pliku z zastosowaniem zwykłej techniki zamykania pliku (instrukcja try) oraz automatycznego zarządzania zasobami (try-with-resources). Wykazano, że właściwie zapisany kod programu ma duży wpływ na wydajność programu Javy. Odpowiednia konstrukcja kodu Javy może znacznie skrócić czas wykonywania programu Javy.

The article discusses some aspects of the efficiency of programming in Java. Performance testing of Java code related to automatic resource management were conducted. The measurements of the runtime of the program for operation in the field of streaming read and write the file using the try and a try-with-resources. The research has shown that a properly written program code has a large impact on the efficiency of a Java program. The proper design of Java code can significant-ly shorten the runtime of the Java program.
