Mau Sharing nih kawan . Program ini sama seperti MP3 Player simak yaaaaa ;)
Gambar dibawah ini adalah hasil desain nya Text Reader .
*Fungsi Button*
a.)Add File Text : menambahkan text yang kalian inginkan .
"kalau saya buat di notepad , jika dijalankan akan keluar hasilnya tetapi di program saya sendiri selain notepad keluar nya tidak seperti yang saya harapkan"
b.)Read : membaca hasil document ketika menekan tombol tersebut.
c.) Delete List : untuk menghapus list
d.) Clean : membersihkan
Dibawah ini adalah codingnya :
package Praktek4;
import java.io.*;
import javax.swing.DefaultListModel;
import javax.swing.JFileChooser;
import java.net.URL;
import javax.swing.JFrame;
/**
*
* @author user

public class Reader extends javax.swing.JFrame {
private String baru;
private String readFile(File file){
String result = "";
try
{
FileInputStream fis = new FileInputStream(file);
BufferedInputStream bis = new BufferedInputStream(fis);
DataInputStream dis = new DataInputStream((bis));
while(dis.available() != 0)
{
result += dis.readLine() + "\n";
}
}
catch(FileNotFoundException e)
{
}catch(IOException e)
{
}
return result;
}
DefaultListModel model = new DefaultListModel();
