I. KIRISH Bugungi kunda infarmatika va axborot texnalogiyalari juda jadallik bilan rivojlanmoqda. Biz bugun mobil aloqa, internet, videotelefon tizimi, raqamli televideniya, zamonaviy bank xizmatlari, lizing, sug urta, audit, injiniring va boshqa zamonaviy xizmat turlarini rivojlantirishga alohida e tibor qaratmoqdamiz. Java dasturlash tilida ishlab chiqarilgan dasturlar XXI asrdagi eng ko`p ishlatiladigan, ommalashib borayotgan dasturlar sarasiga kiradi. Demak, O`zbekiston uchun bu tizimida yaratilgan milliy - zamonaviy dasturlar ishlab chiqish informatika va axborot texnologiyalari sohasidagi barcha dasturlovchilar uchun birinchi darajali masalalardan hisoblanadi. Shu maqsadda men ham shu tizimida ishlovchi aeroport ishini elektronlashtruvchi dastur tayyorladim. Bunday dasturni yaratishda men ham Java dasturash tilidanfoydalandim. Java tilining ustunliklaridan biri u platforma tanlamasligi. Bu dasturni yaratishdan maqsad: obyektga yo naltirilgan java dasturlash tilini mukammal o rganish, javada foydalanuvchi interfeyslarini(java Swing) yaratishni o rganish, malumotlar bazasi bilan ishlashni o rganish, aeroport axborot tizimini avtomatlashtirish. Bu dastur aeroport tizimiga yangi yondoshuv desak ham mubolog a bo lmaydi. Chunki dastur juda qulay interfeysga ega. Har bir sohada ATlar tezlik bilan kirib borgani sari bu sohada ish olib boruvchi mutaxassislar soni ham ko payib bormoqda va bu sohada yetuk mutaxasisga aylanish uchun bizga yaratilgan imkoniyatlardan unumli foydalanishimiz kerak. 3

II. NAZARIY QISM 2.1. Java dasturlash tili haqida Tarixi: Java dasturlash tili eng yaxshi dasturlash tillaridan biri boʻlib unda korporativ darajadagi mahsulotlarni(dasturlarni) yaratish mumkin.bu dasturlash tili Oak dasturlash tili asosida paydo boʻldi. Oak dasturlash tili 90-yillarning boshida Sun Microsystems tomonidan platformaga(operatsion tizimga) bogʻliq boʻlmagan holda ishlovchi yangi avlod aqlli qurilmalarini yaratishni maqsad qilib harakat boshlagan edi. Bunga erishish uchun Sun hodimlari C++ ni ishlatishni rejalashtirdilar, lekin baʼzi sabablarga koʻra bu fikridan voz kechishdi.oak muvofaqiyatsiz chiqdi va 1995-yilda Sun uning nomini Java ga almashtirdi, va uni WWW rivojlanishiga hizmat qilishi uchun maʼlum oʻzgarishlar qilishdi. Java Obyektga Yoʻnaltirilgan Dasturlash(OOP-object oriented programming) tili va u C++ ga ancha oʻxshash.eng koʻp yoʻl qoʻyildigan xatolarga sabab boʻluvchi qismalari olib tashlanib, Java dasturlash tili ancha soddalashtirildi. Java kod yozilgan fayllar(*.java bilan nihoyalanuvchi) kompilatsiyadan keyin bayt kod(bytecode) ga oʻtadi va bu bayt kod interpretator tomonidan oʻqib yurgizdiriladi. Imkoniyatlari: Bugungi kunga kelib kompyuter va Internetda ishlovchi ko plab foydalanuvchilar Java haqida bir oz bo lsada tushunchaga ega bo lganlar. JAVA ning C & C++ dan ustunligi WORA - Write Once, Run Anywhere (portable). Xavfsizlik (ishonch yo q kodni xavfsiz ishga tushirish). Xotirani xavfsiz boshqarish (avtomat ravishda musorlarni yig adi) Tarmoqga dasturlash Ko p oqimli (Multi-thread) dasturlash Dinamik & kengaytirish Class lar alohida fayllarda saqlanadi Kerak bo lsa ishlatiladi Dinamik ravishda imkoniyatini oshirish xam mumkin kerak bo lsa. 4

Quyidagi farqlar bilan Java C/C++ dan ajralib turadi header fayllar yo q Preprocessor lar yo q Goto yo q Unicode belgilar Avtomat musorlarni yig adi Ko rsatkich (pointer) yo q Operatorlarni peregruzga qilish yo q 100% OYDT hamma narsa class Global o zgaruvchi va funksiyalar yo q Java tili Sun Microsystems tomonidan 1991 yil bitovoy ustroystvaga dasturlar ishlab chiqishdan boshlangan. Java dasturlash tili James Gosling tomonidan yaratilgan. Java ning birinchi nomi Oak bo lgan. Birinchi ofitsialniy versiya - Java 1.0, 1996 yil taqdim qilingan. Platforma Java dastirlash tilida C va C++ tilining konstruksiyalari, operatorlari va funksiyalaridan yetarlicha foydalanilgan bo lib, u yangicha uslubdagi ob yektga yo naltirilgan tamoyillar kiritilgan. Unda dastur tuzish va o rganishning osonligi, yaratilgan dasturlarning ixtiyoriy platformada ishlata olish, Internet uchun ixcham dasturlar tuzish, xotirani chiqindi lardan avtomatik tozalash, imkoniyatining 5

mavjudligi uning ommabopligini oshirdi. Java dasturlari Java virtual mashinasi (JVM) deb ataluvchi mexanizmning bayt-kodlari orqali kompilyatsiya qilinganligi uchun ixtiyoriy operatsion tizimda ishlay oladi. Shu sababli, Java dasturlarining ishga tushirilishida vaqt ko proq talab qilinadi. Ko pchilik foydalanuvchilar uni shu tomonlama tanqid ostiga olishadi. Java tilining asosiy yutuqlaridan biri uning tez o zgaruvchanligidir. Bu til dasturlash muhitiga va dasturlash yondashuvlariga tez moslasha oladi. Undan nafaqat ilovalar yaratishda, balki Internet uchun dasturlar yaratishda ham foydalanish mumkin. Xavfsizlik (ishonch yuq kodni xavfsiz ishga tushirish). Xotirani xavfsiz boshqarish (avtomat ravishda keraksiz ma lumotlarni yig adi) Tarmoqda dasturlash Ko p oqimli (Multi-thread) dasturlash Quyidagi farqlar bilan Java C/C++ dan ajralib turadi header fayllar yo q Preprocessorlar yo q Goto yo q Unicode belgilar Avtomat musorlarni yig adi Ko rsatkich (pointer) yo q Operatorlarni qayta yuklash qilish yo q Dasturda barcha vazifalar class tushunchasi bilan boshlanadi Global o zgaruvchi va funksiyalar yo q 2.2.Ma lumotlar bazasi tuzilmasi Relyatsion ma'lumotlar bazasini boshqarish tizimi - o`zining ma'lumotlar strukturasi oddiyligi bilan, foydalanuvchi uchun jadval ko`rinishida joylashtirilishi bilan va ma'lumotlar ustidan oson hisob-kitob amallarini bajarish imkoniyati mavjudligi bilan ajralib turadi. Hozirda relyatsion ma lumot bazalari o zining qulayligi tufayli keng miqyosda ishlatilmoqda. Relyatsion ma lumot bazalari ma lumotlarni jadvallarga joylashgan va 6

jadvallar orasida mos bog liqliklarni, ya ni munosabatni (relyatsiyani) o rnatishga asoslangan. Ular jadvallar orasidagi turli bog liqliklarni o rnatish, ma lumot kiritish shakllarini yaratish, hisobot shakllarini chiqarish, turli so rovlar (Zaprosi) tuzish imkonini beradi. Relatsion model ma'lumotlarni ikki o`lchamli jadvalda tartiblashga asoslangan. Har bir relatsion jadval ikki o`lchamli massivdan iborat bo`ladi va quyidagi hususiyatlarga ega: -Jadvalning bir ustunidagi barcha kataklar bir hil tipga mansub(misol uchun bir ustun barcha elementlari tipi simvolli yoki raqamli); -Jadvalda bir xil qatorlar mavjud emas; -Ustun va qatorlar ketmaketligi turlicha bo`lishi mumkin; Relatsion ma'lumotlar bazasi boshqarish tizimining asosiy tushunchalari bu: 2.3. Java swing haqida Swing tushunchasi javaning eski avlodlarida mavjud bo lmagan. Unig o rniga ma lum kamchiliklarga ega bo lgan AWT(Abstract Window Toolkit) qo llanilgan. AWTlar foydali ammo ma lum kamchiliklarga ega ya ni cheklangan grafik interfeysga ega. Javaning ommalashishi bilan ko p o tmay bunday kamchillikka boshqa yondoshuv zarurligi ayon bo ldi. Yechim esa swing bo lib chiqdi. 1977 yilda e lon qilingan swing JFS(Java Foundation Classes) qisimini ichiga o rnatilgan. Swing komponenta va konteynerlarni o z ichiga oladi. Umuman olganda, java kompanentalari JCompanent klasidan voris qilib olingan. Java/SWING nima JAVA uchun GUI Framework JAVA dasturlarini look and feel holatiga keltirish Java Foundation Classes (Sun Microsystems) bir qismi IFC (Netscape) va JFC (Sun Microsystems) qo shilgani Java Standard Edition 1.2 versiyasidan boshlab paket shaklida qo shilgan GUI controllar java dastur orqali generatsiya qilinadi Ko rinishi va funksionallkin jihatidan Windows, Mac va Linux OS laridaka 7

Swing kompanentalari SWING Layots AWT va Swing klaslarining layout manager lari: BorderLayout BoxLayout CardLayout FlowLayout GridBagLayout GridLayout GroupLayout SpringLayout Java/SWING BorderLayot BorderLayout Har bir content pane boshlang ichda BorderLayout inisalizatsiya qilinadi. BorderLayout componentlarni 5 ta maydonga qo yadi: top, bottom, left, right, va center. 8

2.5. Netbeans muhitida haqida Dastur NetBeans muhitida yaratildi. Bunga sabab bu muhitning qulay interfeysga ekani. Bu oyna NetBeansning ochilish paytida muhit kompanentalarini yuklash jarayoni. Quyidagi oyna NetBeansning ilk oynasi bo li yuqori qismida muxit kompannentalari joylashgan. Chap qismida bizda mavjud bo lgan dasturlar va klaslarni ko rish mumkin. Markazda ishchi soha joylashgan bo lib unda dasturga ishlov berishimiz mumkin. 9

Bu oynada dasturning asosiy oynasi ochilib turganini ko rishingiz mumkin. Dastur kodini ko rish uchun har bitta tugma (button) ustiga bosamiz va ma lumotlarga ishlov berish imkoniyatiga ega bo lamiz. Dastur yaratilish jarayonida ma lum qiyinchiliklarga ega bo lindi. Birinchi navbatda aeroport tizimini o rganib chiqishga to g ri keldi. NetBeans muxitidagi qulayliklar tufayli bu tizimni amalga oshirish oson bo ldi. 10

III.AMALIY QISM 3.1. Dastur ma lumotlar bazasi tuzilmasi MySQL da yartilgan baza quyidagicha tuzilgan. Quyida turgan jadval aeroport ma lumotlar ba zasining asosiy jadvali.

IV. XULOSA Men bu dasturni ishlash jarayonida juda ko p narsalarni o rgandim va kata amaliyotga ega bo ldim. Shular jumlasidan OOPni chuqurroq o rganishga muvaffaq bo ldim. Undan tashqari ma lumotlar bazasi bilan ishlash jarayonida ko plab yangi narsalarga duch keldim va bularni o rganish uchun izlanishimga to g ri keldi. Bu ishning samarasida dastur bazasini mukammal tarzda yaratishga harakat qildim. Bugungi kun har qanday masalaning yechimi kompyuter yordamida hal qilinayotgan bir davr hisoblanadi. Va hozirda hech bir soha yo qki unda kompyuter, internet foydalanilmaydigan. Har bir sohaga chuqur kirib borayotga yangi texnologiyalar, insoniyat taraqqiyotiga o zining bemisl ulushuni qo shmoqda. Shuni ham ta kidlash lozimki, hozirda axborot sohasini rivojlantirish va faoliyatini yaxshilash bo yicha ham O zbekistonda bir qator Prezident Farmonlari va qonun hujjatlari ishlab chiqilmoqda. Bular esa o z navbatida aholi ongini oshirish va malakali servis xizmatni tashkil qilishga qaratilgandir. Xulosa qilib aytganda, hozirgi kunda axborotni istalgan vaqtda va ishonchli manba orqali qabul qilish va undan samarali foydalanish eng asosiy masaladir. 16
