Pengenalan Teknologi Java OOP Java (IX307)

Bahasan Kebutuhan akan bahasa pemrograman Sejarah Java Java sebagai sebuah Teknologi Program Java sederhana – hello world

Mengapa Perlu Bahasa Pemrograman ? Manusia  Manusia : bahasa Manusia  Komputer : bahasa pemrograman => Untuk Berkomunikasi Bahasa Pemrograman : memberikan perintah, supaya komputer melakukan apa yg diinginkan manusia.

Komputer dan Programnya Pemrograman merupakan urutan aktivitas : Analisis Desain Implementasi/Coding Pengujian Sebagian besar adalah kegiatan tanpa menggunakan keyboard. Kunci menguasai pemrograman : 1. latihan !!! (+ 2. baca program orang lain, 3. belajar algoritma & struktur data)

Tingkatan Bahasa Pemrograman Tk. Lebih Tinggi: Logic Programming (Prolog) dan Functional Programming (Haskell, Lisp) Tk. Tinggi : Pascal/Delphi, C++, BASIC/VB, Java, C#, Fortran, Ruby, PHP, Python Tk. Sedang : C Tk. Rendah : Assembler Tk. Hardware : Bhs Mesin Bhs Logic/Functional Bhs Tk. Tinggi Bhs Tk. Sedang Bhs Assembler Bhs Mesin
