Tidak dapat dipungkiri bahwa user interface merupakan salah satu komponen penting di dalam sebuah website/aplikasi. Terlepas dari fungsi aplikasinya, sebuah aplikasi harus memiliki tampilan yang baik dan mudah digunakan oleh penggunanya. Oleh karena itu saat ini banyak perusahaan yang membutuhkan tenaga UI/UX designer untuk menyempurnakan design tampilan pada website/aplikasi mereka. Jika anda berminat untuk menjadi seorang UI/UX designer, berikut rekomendasi UI/UX designer dari saya yang tentunya gratis dan cocok digunakan untuk pemula maupun anda yang sudah lama menggeluti bidang ini. Ga pake lama skuy kita langsung ke rekomendasinya. 1. figma Nah di rekomendasi nomer 1 ini ada figma. Belakangan ini nama figma cukup terkenal di kalangan para UI/UX designer. Figma cukup mudah digunakan bahkan untuk para pemula yang ingin mulai mencoba untuk menggeluti bidang UI/UX designer. Terlebih lagi software ini berbasais web sehinggal anda tidak perlu melakukan instalasi software untu...
Pada postingan kali ini saya akan memberikan contoh program konversi mata bilangan dari desimal, biner, oktal dan hexadesimal di java dengan paradigma OOP. Program yang saya berikan ini berbasis GUI sehingga akan kan user dalam menggunakan program/aplikasi ini nantinya. Baik langsung saja kita masuk ke programnya...
File-file yang ada di program ini berada dalam 1 package.

Keterangan:
- Class Konversi_bilangan.java merupakan main class atau class yang pertama kali dipanggil saat program dijalankan.
- Class Konversi.java merupakan abstract class yang berisi 4 abstract method dimana nantinya semua abstract method ini akan diOverride pada masing-masing class yang melakukan extends(inheritence) ke abstract class ini.
- Class Desimal.java berisi 4 method yang merupakan override dari parent classnya (Konversi.java) yang masing-masing methodnya digunakan untuk mengkonversi bilangan dari desimal ke biner/oktal/hexadesimal.
- Class Biner.java berisi 4 method yang merupakan override dari parent classnya (Konversi.java) yang masing-masing methodnya digunakan untuk mengkonversi bilangan dari biner ke desimal/oktal/hexadesimal.
- Class Oktal.java berisi 4 method yang merupakan override dari parent classnya (Konversi.java) yang masing-masing methodnya digunakan untuk mengkonversi bilangan dari oktal ke desimal/biner/hexadesimal.
- Class Hexadesimal.java berisi 4 method yang merupakan override dari parent classnya (Konversi.java) yang masing-masing methodnya digunakan untuk mengkonversi bilangan dari hexadesimal ke desimal/biner/oktal.
- Class EntitasData.java digunakan untuk membantu program menginputkan data history konversi kedalam ArrayList yang nantinya data di dalam ArrayList tersebut akan ditampilkan di dalam tabel.
