package readFile;

import java.awt.EventQueue; import java.io.*; import java.nio.file.Path; import java.util.StringTokenizer;

import javax.swing.JFileChooser; import javax.swing.JFrame; import javax.swing.JTextField; import javax.swing.JButton; import javax.swing.JTextArea; import javax.swing.text.JTextComponent;

import java.awt.event.ActionListener; import java.awt.event.ActionEvent;

public class frmReadFile {

JFileChooser dialog = new JFileChooser();

private JFrame frmFrmreadfile; private JTextField txtPath;

/\\ \* Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { try { frmReadFile window = new frmReadFile(); window.frmFrmreadfile.setVisible(true); } catch (Exception e2) { e2.printStackTrace(); } } }); }

/\\ \* Create the application. */ public frmReadFile() { initialize(); }

/\\ \* Initialize the contents of the frame. */ private void initialize() { frmFrmreadfile = new JFrame(); frmFrmreadfile.setTitle("frmReadFile"); frmFrmreadfile.setBounds(100, 100, 450, 300); frmFrmreadfile.setDefaultCloseOperation(JFrame.EXI T_ON_CLOSE); frmFrmreadfile.getContentPane().setLayout(null);

txtPath = new JTextField(); txtPath.setBounds(10, 11, 272, 27); frmFrmreadfile.getContentPane().add(txtPath); txtPath.setColumns(10);

JButton btnBrowse = new JButton("Browse"); btnBrowse.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { int pFile = dialog.showOpenDialog(null); if (pFile == JFileChooser.APPROVE_OPTION) { File file = dialog.getSelectedFile(); try { txtPath.setText("" + file); } catch (Exception e) { System.out.println("Error : " + e.getMessage()); } } } }); btnBrowse.setBounds(319, 11, 89, 23); frmFrmreadfile.getContentPane().add(btnBrowse);

JButton btnTampil = new JButton("Tampil Teks"); btnTampil.addActionListener(new ActionListener() { private JTextComponent tmpTeks;

public void actionPerformed(ActionEvent e) { tmpTeks.setText(null); String path = txtPath.getText(); File file = new File(path); try { FileInputStream fstream = new FileInputStream(file); DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; while ((strLine = br.readLine()) != null) { StringTokenizer st = new StringTokenizer(strLine, "."); tmpTeks.setText(tmpTeks.getText() + st.nextToken() + "\n"); } in.close(); } catch (Exception e2) { System.out.println("Error : " + e2.getMessage()); } } }); btnTampil.setBounds(10, 49, 89, 23); frmFrmreadfile.getContentPane().add(btnTampil);

JTextArea tmpTeks = new JTextArea(); tmpTeks.setBounds(10, 81, 398, 168); frmFrmreadfile.getContentPane().add(tmpTeks); }
