4-qadam. “New Класс Java” darchasining «Имя класса»
maydoniga
“Client”, «Пакет» maydoniga “javafx” kiritilib «Готово» tugmasi bosiladi.
5-qadam. Yaratilgan javafx paketi ichidagi Client.java fayliga quyidagi Java
kodi kiritiladi.

9.4-rasm. NetBeans IDE muhiti Client.java
fayli
Client.java fayli yaratilgani kabi 3-5 qadamlar qayta bajarilib Server.java
fayli yaratiladi. Quyidagi Java kod Server.java fayliga kiritiladi.
