Project Stream IO

pertama membuat file dengan nama jenisFile.java
isinya :

package project_io;
import java.io.*;
import javax.swing.filechooser.FileFilter;

class jenisFile extends FileFilter {
private String[] s;
jenisFile(String[] sArg) {
s = sArg;
}
// Tentukan file apa yang akan ditampilkan
public boolean accept(File fArg) {
if (fArg.isDirectory())
return true;
for (int i = 0; i < s.length; ++i)
if (fArg.getName().toLowerCase().indexOf(s[i].toLowerCase()) > 0)
return true;
// selain kedua hal di atas, anggap false
return false;
}
public String getDescription() {
String tmp = "";
for (int i = 0; i < s.length; ++i)
tmp += "*" + s[i] + " ";
return tmp;
}
}
// Jika Extension dari file sesuai syarat, tampilkan


kemudian membuat NEW - JFrame Form kalau aku nama filenya ProjectIO.java

tampilannya seperti ini 

setelah itu mulai mengcoding :D

setelah mengcoding coba running .. jika tidak ada yang error maka tampilannya akan seperti ini 

setelah itu coba kita enkripsi ..

bila sukses maka hasil enkripsinya akan seperti ini 

setelah itu kita diskripsikan ,, bila tidak dimasukkan password maka akan seperti ini

setelah diberi password tampilannya seperti ini

sekian dari saya ,, silahkan dicoba :)

Event Handling

Pengertian Event Handling :

Event Handling merupakan konsep penanganan suatu action yang terjadi. Jadi suatu program akan berjalan saat sesuatu terjadi, misalnya saat tombol diklik, saat combo box dipilih dan sebagainya. Java memiliki beberapa jenis Event Handling, salah satunya adalah class ActionListener yang menangani aksi terhadap tombol.

Konsep Dasar Event Handling : Event berguna untuk menangani interaksi user dengan program, misalnya user memilih sebuah menu dalam aplikasi MIDlet.Untuk menangani event perlu mengimplementasikan interface CommandListener dan atau ItemListener.
CommandListener berfungsi untuk menangani jika user memilih Command tertentu sedangkan ItemListener berfungsi untuk menangani jika user mengubah nilai seperti misalnya mengubah pilihan pada ChoiceGroup.

Contoh Aplikasinya :

import javax.microedition.MIDlet.*;
import javax.microedition.lcdui.*;
public class NotHelloWorld2 extends MIDlet implements CommandListener{
private Command cmdExit;
private Display display;
public NotHelloWorld2()
{
display = Display.getDisplay(this);
cmdExit = new Command("Exit", Command.SCREEN,2);
}
public void startApp()
{
TextBox t = new TextBox("Not ","Not Hello World",256,0);
t.addCommand(cmdExit);
t.setCommandListener(this);
display.setCurrent(t);
}
public void pauseApp()
{
}
public void destroyApp(boolean unconditional)
{
}
public void commandAction(Command cmd,Displayable disp)
{if(cmd==cmdExit)
{
destroyApp(false);
notifyDestroyed();
}
}
}

Pemrograman aplikasi wireless dengan Java/J2ME 24
Pada contoh kedua ini, kita tambahkan sebuah Command untuk keluar dari aplikasi yang telah kita buat pada contoh 1. Ketika program pertama kali dipanggil, maka state berada pada Aktif, disini sebuah TextBox dan Command dibuat. Kemudian program menunggu respon dari user dengan mengimplementasikan CommandListener. Ketika user menekan Command “cmdExit” , maka program memanggil metodh(destroyApp) untuk membunuh MIDlet.

GUI Java

Pengertian GUI Java :

JAVA GUI

Dapat disimpulkan bahwa Java GUI adalah pemrograman dengan bahasa Java yang dibuat menggunakan aplikasi yang berbasiskan GUI. 

Tujuannya adalah menambahkan komponen-komponen yang tidak bisa dibuat dalam basis text. 

Komponen-konponen tersebut bisa berupa tombol, gambar, dll. 

Tujuannya  adalah untuk memudahkan user menggunakan program yang dibuat tersebut.

Apa itu GUI ?
GUI (Graphical User Interface) yaitu Tampilan Antarmuka Grafis dimana user dapat berinteraksi dengan tampilan grafis yang lebih mudah dimengerti. Tidak seperti postingan yang dulu, dimana saya menggunakan konsol command prompt, kali ini akan dibuat GUInya.

Konsep Dasar GUI Java :

• Graphical Object 

• Container (tempat), obyek yang dapat menampung komponen grafis dan tempat yang lebih kecil 
• Contoh: frames, panels

• Component, obyek grafis yang berfungsi untuk menampilkan data, menerima masukan, atau menunjukkan suatu kondisi.
• Contoh: buttons, labels, text fields

• Event, obyek yang merepresentasikan suatu kejadian.
• Contoh: gerakan mouse, penekanan tombol

• Listener, suatu obyek yang menunggu suatu kejadian khusus dan akan bereaksi (melakukan sesuatu) jika kejadian tersebut terjadi

Contoh Aplikasi :

• Pola umum pembuatan aplikasi Java berbasis GUI. Pada aplikasi berbasis GUI yang dasar, kita akan menggunakan Swing, berikut contoh skripnya: 

• Mari kita buat message box untuk user, berikut contohnya:

 

• Nah, mari dicompile:

 

• Setelah dicompile, maka akan muncul GUI program berupa pesan yang kita buat, tapi script yang sebelumnya belum full, berikut contoh full-scriptnya :

 

• Nah, itu adalah contoh pembuatan message box pada Java basis GUI (mirip dengan System.out.println di konsol biasa), pada postingan berikutnya, kita akan membahas bagaimana menerima input dari user dan mengolahnya.

Stream IO

Pengertian Stream IO :

- I/O : adalah singkatan dari Input / Output dan mengacu pada transfer data ke atau dari aplikasi.

- Stream : Keadaan dari sebuah file atau sebuah device yang memungkinkan rangkaian item dapat dibaca atau ditulis.

Konsep Dasar Stream IO :

- Untuk membaca, program membuka stream pada sumber ( file, memory, socket) dan membaca informasi secara sekuensial. 

- Untuk menulis, program mengirim informasi ke tujuan dengan cara membuka stream tujuan, selanjutnya menulis informasi secara sekuensial.

Byte stream (8 bit) 
digunakan untuk byte, integer, dan simple data type yang lain. Misal: numerical data, executable programs, dll

Character stream (16bit)

digunakan untuk data tekstual (teks), mendukung unicode. Misal: text files 

Input Stream

Subclass-subclass dari inputStream adalah : AudioInputStream, ByteArrayInputStream, FileInputStream, FilterInputStream, PipedInputStream, SequenceInputStream, dan StringBufferInputStream.

Dua method utama dari InputStream adalah :

• Read : Method ini digunakan untuk membaca stream.

• Close : Method ini digunakan untuk menutup koneksi input stream.

Contoh Aplikasi :

nama project : InputStream.java

import java.io.*;
class InputStream {
 public static void main(String[ ] args) throws IOException {
  byte[ ] data = new byte[10];
  System.out.print("Ketik 10 buah karakter :");
  System.in.read(data);
  System.out.print("Karakter yang Anda ketik yaitu : ");
  for(int i=0;i<data.length;i++) {
   System.out.print((char)data[i]);
  }
 }
}

ini outputnya :

 

Output Stream

Subclass-subclass dari outputStream adalah :

1. ByteArrayOutputStream : digunakan untuk menuliskan stream menjadi byte array.
2. FileOutputStream : digunakan untuk menulis pada file
3. FilterOutputStream : merupakan superclass dari subclass-subclass seperti
4. DataOutputStream, BufferOutputStream, PrintStream, CheckedOutputStream
5. ObjectOutputStream : digunakan untuk menuliskan objek pada OutputStream.
6. PipedOutputStream : digunakan untuk menjadi output dari PipedInputStream.

Sebagian method-method OutputStream adalah :

• Voidclose() : Menutup output stream yang aktif dan melepaskan sumber daya terkait dengan stream tersebut

• Void flush() : Melakukan flush output stream dan memaksa semua byte buffer untuk dituliskan keluar

• Void write(byte[ ] b) : Menulis sebanyak b.length dari byte array ke output stream

• Void write(byte[ ] b, int off, int len) : Menuliskan sebanyak len byte dari byte array b dimulai dari index off

Contoh Aplikasi :

nama project : OutputStream.java

import java.io.*;
class OutputStream {
 public static void main(String[] args) throws IOException {
  byte[] data = {'a','b','c','d','e','f','g'};
  System.out.write(data,3,4);
  //pindah baris
  System.out.write('\n');
  //tulis semua isi array data
  System.out.write(data);
 }
}

ini outputnya : 

sekian dan terima kasih , jangan lupa dicoba ya :)

DATA TEMAN

hai ketemu lagi dengan saya :D

disini saya mau bagi bagi tentang vb.net lo , ini salah satu tugas saya semester 2 .

semoga bermanfaat bagi anda .

pertama buat desain seperti ini ya .. 

*RECORD KE : (label1)

*Nama, Gender, TTL, Agama, Rumah (textbox)

*<<, <, >, >>, Update, Delete ini berada di panel

*button X yang dikasik warna merah

*Addnew, Commit (button)

*yang kotak itu pakek picture box1

 

kedua itu buat databasenya ..

setelah buat databasenya save dengan nama (Database1) dengan format access 2007 

ketiga save gambar dengan format JPEG dengan nama image1 dan seterusnya sebanyak yang kamu mau .

6 Makanan yang Memutihkan Gigi

hai ,, ada tips buat mutihin gigi lo :D

aku dapat info ini dari yahoo jadi yang belum sempat liat bisa liat disini ya :)


1. Stroberi
Buah cantik ini memproduksi enzim malic acid yang membantu memutihkan gigi. Selain dengan langsung memakannya, stroberi bisa dimanfaatkan untuk memutihkan gigi dengan cara dihaluskan, digosokkan ke gigi, diamkan selama lima menit lalu bilas dan gosok gigi seperti biasa.

2. Buah-buahan dan sayuran yang renyah
Contoh terbaik adalah apel, seledri, dan wortel. Menggigit dan mengunyah buah dan sayuran seperti ini akan membantu membersihkan plak, "menggosok" gigi agar lebih putih bersinar, dan meningkatkan produksi air liur yang baik bagi kesehatan mulut.

3. Keju
Keju dan bahan olahan susu lainnya seperti yoghurt mengandung lactic acid yang berfungsi melindungi gigi. Sebuah penelitian menunjukkan bahwa anak-anak yang mengonsumsi yoghurt empat kali seminggu lebih terlindung dari pembusukan gigi dibanding anak-anak yang tak minum yoghurt. Sedangkan untuk memutihkan gigi, keju adalah pilihan yang baik karena selain melindungi gigi dari kebusukan, keju juga mengandung kalsium dan fosfor yang berguna dalam pembentukan enamel gigi.

4. Jeruk dan nanas
Saat mengonsumsi jeruk, nanas, dan buah-buahan asam lainnya, mulut memproduksi air liur lebih banyak, yang membantu membersihkan gigi secara alami.

5. Baking soda
Sebuah penelitian tahun 2008 menemukan bahwa pasta gigi yang mengandung baking soda berfungsi lebih baik dalam membersihkan plak. Anda bisa saja menggunakan baking soda langsung untuk membersihkan gigi, namun para dokter menyarankan agar hal ini tak dilakukan terlalu sering karena bisa mengikis enamel gigi. Pilihan paling aman adalah menggunakan pasta gigi yang mengandung baking soda.

6. Permen karet yang mengandung xylitol
Xylitol adalah pemanis alami yang dapat mencegah plak. Xylitol juga menetralkan tingkat keasaman di dalam mulut dan meningkatkan produksi air liur untuk membersihkan gigi.

Semangat semoga bermanfaat ,, makasih buat Yahoo juga ya :)
