Mavzu: Temir yo‘l kassasida, chipta sotish va bo‘sh o‘rinlar hisobi

DriverManager.getConnection metodi ma’lumotlar bazasi ulanishini o‘rnatadi. Ushbu metod ma’lumotlar bazasi URL manzilini talab qiladi, bu sizning DBMSingizga qarab turlicha bo‘ladi. Quyida maʼlumotlar bazasi URL manzillarining baʼzi misollari keltirilgan:

1. 
   MySQL: jdbc:mysql://localhost:3306/, bu erda localhost ma’lumotlar bazasini joylashtiradigan server nomi va 3306 port raqami
   
2. 
   Java DB: jdbc:derby:testdb;create=true, bu erda testdb ulanish uchun ma’lumotlar bazasi nomi va create=true DBMSga ma’lumotlar bazasini yaratishni buyuradi.
   

5. 
   “Temir yo‘l kassasida, chipta sotish va bo‘sh o‘rinlar hisobi” dasturiy ta’minotini tuzish va amalda sinash.
   

Bu dasturimizni tuzishda java swing shuningdek MySQl tillaridan foydalaniladi.

JFrame - bu ekranda oynani ko‘rsatadigan Swingning yuqori darajali konteyneridir. Ramka - menyu paneli, panellar, teglar, matn maydonlari, tugmalar va boshqalar kabi boshqa komponentlar tayanadigan asosiy oyna. Deyarli har bir Swing ilovasi JFrame oynasidan boshlanadi. Quyida shular yaratilgan.
