PROGRAM STUDI TEKNIK INFORMATIKA FAKULTAS TEKNOLOGI INFORMASI UNIVERSITAS MERCU BUANA YOGYAKARTA 2015
Kata Pengantar Puji syukur penulis panjatkan kepada Tuhan Yang Maha Esa yang telah memberikan rahmat dan karunianya, sehingga penulis dapat menyelesaikan Laporan Praktikum Pemrograman Berbasis Java ini. Tugas Praktikum Pemrograman Java ini merupakan salah satu matakuliah yang wajib ditempuh di Fakultas Teknologi Informasi Universitas MercuBuana Yogyakarta. Laporan Praktikum ini disusun sebagai pelengkap Tugas praktik yang telah dilaksanakan lebih kurang 1 Semester ganjil. Dengan selesainya laporan kerja praktek ini tidak terlepas dari bantuan banyak pihak yang telah memberikan masukan-masukan kepada penulis. Penulis menyadari bahwa masih banyak kekurangan dari laporan ini, baik dari materi maupun teknik penyajiannya, mengingat kurangnya pengetahuan dan pengalaman penulis. Oleh karena itu, kritik dan saran yang membangun sangat penulis harapkan.

ANALISA PROGRAM Struktur perulangan dibagi menjadi tiga, Yaitu for, while, dan do while. Struktur for pada umumnya digunakan untuk melakukan perulangan yang banyaknya sudah pasti atau sudah diketahui sebelumya. Struktur while adalah jenis perulangan yang mendefinisikan kondisi di awal blok. Ini artinya apabila kondisi tidak terpenuhi (false) maka proses 6
perulangan pun tidak akan pernah dilakukan. Struktur do-while sebenarnya mirip dengan struktur while. Perbedaannya hanya terletak pada penempatan kondisinya saja.

ANALISA PROGRAM Inheritance atau pewarisan adalah suatu pewarisan sifat dari suatu class kepada subclassnya. Dengan adanya pewarisan ini, maka kita tidak perlu menuliskan kode program dari awal, cukup menuliskan spesifikasi dari class tersebut. Didalam inheritance terdapat isitilah superclass dan subclass. Superclass adalah class induk atau class orang tua, sedangkan subclass adalah class anak. Semua property, methode, ataupun konstruktor yang dimiliki oleh superclass jika diwariskan, maka subclass memiliki semua yang dimiliki oleh superclass. Untuk melakukan pewarisan / inheritance sebuah class, kita harus menggunakan kata kunci extends.
