1-amaliy mashg’ulot. Mavzu: tcp kliyent tarmoq dasturini amaliy o‘rganish. Ishning maqsadi

Ishni bajarish tartibi:
Ishni Eclipse yoki NetBeans IDE ishlab chiqarish muhitini yuklash bilan boshlaymiz. Buning uchun ish stolida turgan Eclipse yoki NetBeans IDE muhiti yorlig’ini sichqonchaning chap tomonini ikki marta bosib yuklaymiz. Bizning holatda NetBeans IDE muhiti ishga tushadi.

Rasm 3.1. Net Beans IDE ishga tushish jarayoni
Quyidagi rasmda NetBeans IDE muhitining asosiy darchasi yuklangan.

Rasm 3.2. Net Beans IDE muhiti asosiy darchasi
Shundan so’ng «Fayl» menyusidan «Otkrыt proekt» bo’limi tanlanganda paydo bo’lgan darchadan «Talabaning_Ismi» proyektini tanlab “Otkrыtie proekta” tugmasi bosiladi.
So’ng ochilgan “Talabaning_Ismi” loyihasi ustiga sichqonchaning o’ng tumasi bir marta bosiladi, paydo bo’lgan kontekst menyudan «Novыy → Klass Java» tanlanadi.

Rasm 3.3. NetBeans IDE muhiti Yangi klass yaratish
“New Klass Java” darchasining «Imya klassa» maydoniga “Client”, «Paket» maydoniga “udp” kiritilib «Gotovo» tugmasi bosiladi.

Rasm 3.4. NetBeans IDE muhiti «New Klass Java» darchasi
