Graphic User Interface

Dalam teknologi komputasi, antarmuka pengguna grafis atau APG (Inggris: Graphical User Interface atau GUI) adalah jenis antarmuka pengguna yang menggunakan metoda interaksi pada piranti elektronik secara grafis (bukan perintah teks) antara pengguna dan komputer.

GUI menjadi salah satu faktor kemudahan dalam penggunaan komputer, piranti bergerak seperti pemutar MP3, pemutar media portabel atau piranti permainan, peralatan rumah tangga, dan peralatan kantor. GUI menggambarkan informasi dan perintah yang tersedia untuk pengguna menggunakan ikon grafis.

Contoh: Microsoft Windows, MacOS dan Xwin menggunakan jenis GUI yang berbeda.

apa itu OOP ?
OOP adalah pembuatan program java dengan class class baru yang akan mempermudah, pembuatan program kita. berikut contoh pemograman OOP saya.

1. Main Class (Mata Kuliah)

package matakuliah;
import java.util.Scanner;
public class Matakuliah {

public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String film;

System.out.print("Masukkan Mata Kuliah Apa Yg Ingin Ditampilkan (BP/KECAP/PTI): ");
film = scan.next();

if ("BP".equals(film)){
BahasaPemograman aini = new BahasaPemograman();
aini.BP();

}

else if ("KECAP" .equals(film)){
KecakapanPribadi ainii = new KecakapanPribadi();
ainii.Kecap();

}

else {
PengantarTeknologiInformasi ainii= new PengantarTeknologiInformasi ();
ainii.PTI();
}
}
}

2. Class ke -1 ( Bahasa Pemograman)

package matakuliah;
public class BahasaPemograman {
void BP(){
System.out.println(" ");
System.out.println("#############################################################");
System.out.println("# Yang Akan Di Pelajari Dalam Mata Kuliah Bahasa Pemograman #");
System.out.println("#############################################################");

System.out.println("1.Variabel,Tipe Data,Operator");
System.out.println("2.Pengkondisiian/Percabangan");
System.out.println("3.Pengulangan/LOOPING");
System.out.println("4.ARRAY");
System.out.println("5.Class STRING");
System.out.println("6.METHOD");
System.out.println("7.OOP");
System.out.println("8.SWING");
}

}

3. Class ke -2

package matakuliah;
public class KecakapanPribadi {
void Kecap(){
System.out.println(" ");
System.out.println("**************************************************************");
System.out.println("* Yang Akan Di Pelajari Dalam Mata Kuliah Kecakapan Pribadi *");
System.out.println("**************************************************************");

System.out.println("1.Hirarki Maslow");
System.out.println("2.SWOOT");
System.out.println("3.Tugas Faktor Pengaruh Persepsi ");
System.out.println("4.Jenis Komunikasi");

}

}

4. Class ke -3

package matakuliah;
public class PengantarTeknologiInformasi {
void PTI(){
System.out.println(" ");
System.out.println("-------------------------------------------------------------------------");
System.out.println("- Yang Akan Di Pelajari Dalam Mata Kuliah Pengantar Teknologi Informasi -");
System.out.println("-------------------------------------------------------------------------");

System.out.println("1.Sejarah Komputer & Hardware");
System.out.println("2.Hardware II (Elemen Dasar Sistem Komputer)");
System.out.println("3.Software & Aplikasi");
System.out.println("4.Grafik, Media Digital, Multimedia");
System.out.println("5.Basis Data");
System.out.println("6.Jaringan dan Komunikasi Data");
System.out.println("7.Internet dan Web");
System.out.println("8.Keamanan Komputer");
System.out.println("Pemanfaatan IT di berbagai bidang");
System.out.println("Sistem Informasi dalam bisnis");

}

}
