Mari Belajar Java Menggunakan Netbeans

hallo kawan2, udah lama ni saya g posting2, maaf karena saya kebanyakan tugas kuliah, UTS dan UAS..

kali ini saya pngen share sedikit tentang pemrograman java memakai netbeans, kawan-kawan pasti tau donk?? hayo masa anak teknik informatika g tau sih?,

kalo kawan2 tau UNINDRA disana java hanya menggunakan Blue J saja, dari Java Pengenalan sampe sekarang..

kayanya seperti nasi tanpa lauk,, hha jadi laper nii, maklum saya posting ini dengan keadaan belum sarapan pagi.. :)

saya coba jelaskan sedikit apa itu netbeans,

Netbeans adalah software programming java yang kaya fitur j2ee, j2Me, mobilitypack dll, dan biasa digunakan untuk membuat pemrograman java yang berbasis GUI, untuk games, applikasi dll,

sayangnya dikampus saya java programmingnya tidak menggunakan Netbeans.. hiksd2.. T.T

ini penampakannya :

Udah siap belum untuk memulai program java pertama dengan netbeans?
jika kawan belum punya silahkan download softwarenya disini

jangan lupa pastikan JDKnya telah terinstall dikomputer/laptop, klo belum punya silahkan download disini

kalau sudah, buka netbeansnya lalu klik file-newproject choose project-Java Application lalu buat project yg ingin kita buat, misalkan kita beri nama projectnya Coba kemudian hilangkan pilihan Create Main Class, karena kita langsung membuat main class pada form program sederhana yg akan kita buat.

Klik kanan pada Project yang baru dibuat, pilih New | JFrame Form…

Beri nama Form yang baru dibuat dengan nama hadiah, sebagai contoh tutor . Klik finish. Kita akan diberi satu buah form yang bisa didesain secara leluasa.
