Bonjour à tous !
J'avais déjà fais appel a vous par le passé et j'en était satisfait .
J'ai donc cette fois-ci un problème d'un autre genre.
J'ai un projet en Java qui consiste a détecter les Pdf a partir d'un chemin donné.
Mon code se compose en plusieurs classe:
 
la première contient le main  c'est elle qui va créer une fenêtre en faisant appel à la classe que j'ai créée
voici donc le main
 

Code :
  1. package pdfFinder;
  3. public class MainPdfFinder {
  5. public static void main(String[] args) {
  6.  new PdfViewer();
  7. }
  9. }

 
 
et maintenant voici ma fenêtre attention c'est gros !  
 

Code :
  1. package pdfFinder;
  3. import java.awt.BorderLayout;
  4. import java.awt.Component;
  5. import java.awt.FlowLayout;
  6. import java.awt.GridLayout;
  7. import java.awt.event.ActionEvent;
  8. import java.awt.event.ActionListener;
  9. import java.io.File;
  10. import java.io.IOException;
  12. import javax.swing.ImageIcon;
  13. import javax.swing.JButton;
  14. import javax.swing.JFrame;
  15. import javax.swing.JLabel;
  16. import javax.swing.JPanel;
  17. import javax.swing.JScrollPane;

  57. private JLabel numberPdfLab = new JLabel();
  58. private JLabel southLab = new JLabel(" Create by CHAUMIENNE Charles " );
  60. private JTextField viewerText = new JTextField(20);
  61. private JTextField searchText = new JTextField(20);
  63. private String title[] = {"name", "number of pages", "size", "last modification", "path", "version", "encrypted"};
  64. private JTable tab = new JTable();
  66. public PdfViewer() {
  67.  setTitle("PDF Finder" );
  68.  setSize(570, 585);

  136.     find.afficher();
  137.     center.updateUI();
  139.    }
  141.   } catch (IOException e) {
  142.    e.printStackTrace();
  143.   }
  144.  }
  145. }
  147. class OpenListener implements ActionListener{
  148.  public void actionPerformed(ActionEvent a){
  149.   if( chooseViewer == true){
  150.   }
  151.  }
  152. }
  154. public void northPanel(){
  155.  viewerPan.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));

  208.  center.add(new JScrollPane(tab));
  209.  getContentPane().add(center, BorderLayout.CENTER);
  210. }
  212. }


 
Lorsque le StartListener est appelé il fait appel à une methode SearchAlgo qui est l'algorithme de recherche qui se trouve dans une classe que j'ai nommé PdfFinder et qui contient une aray liste d'une autre classe de ma création qui se nomme Pdf  
 
voici donc PdfFinder
 

Code :
  1. package pdfFinder;
  4. import java.io.File;
  5. import java.io.IOException;
  6. import java.util.ArrayList;
  7. import java.util.Iterator;
  9. import com.itextpdf.text.pdf.PdfReader;
  11. public class PdfFinder {
  13. private ArrayList<Pdf> lsPdf = new ArrayList<Pdf>();
  15. private String pdfViewerPath;
  16. private int nbPdf =0 ;
  18. public PdfFinder() {
  20. }
  22. public static boolean isPdf(String path) {
  23.  try {
  24.   PdfReader pdfR = new PdfReader(path);
  25.   return true;
  26.  }
  28.  catch (IOException e) {
  29.   return false;
  30.  }
  31. }
  33. public void searchAlgo(File dir) throws IOException {
  34.  File[] file;
  35.  file = dir.listFiles();
  36.  for (int i = 0; i < file.length; i++) {
  37.   if (isPdf(dir.getAbsolutePath())) {
  38.    Pdf pdf = new Pdf(file[i].getAbsolutePath());
  39.    lsPdf.add(pdf);
  40.    afficher(pdf);
  41.    setNbPdf (getNbPdf() + 1 );
  42.   }
  43.   else if (file[i].isDirectory()) {
  44.    searchAlgo(file[i]);
  45.   }
  46.  }
  47. }
  49. public boolean verifPath(String path){
  50.  boolean exist ;
  51.  File file = new File(path);
  52.  exist = file.exists();
  53.  return exist;
  54. }
  56. public Object[][] setData(){
  57.  Object [][] data = new Object[lsPdf.size()][7];
  58.  for(int i=0 ; i < lsPdf.size() ; i++){
  59.   data[i][0] = (lsPdf.get(i).getNameFile());
  60.   data[i][1] = (lsPdf.get(i).getNbPages());
  61.   data[i][2] = (lsPdf.get(i).getSize());
  62.   data[i][3] = (lsPdf.get(i).getLastModif());
  63.   data[i][4] = (lsPdf.get(i).getPath());
  64.   data[i][5] = (lsPdf.get(i).getVersion());
  65.   data[i][6] = (lsPdf.get(i).getIsEncrypted());
  66.  }
  68.  return data;
  69. }
  71. public void afficher(Pdf pdf){
  72.    System.out.println(pdf.toString());
  73. }
  75. public void setNbPdf(int nbPdf){
  76.  this.nbPdf = nbPdf;
  77. }
  79. public int getNbPdf(){
  80.  return nbPdf;
  81. }
  82. }


 
et maintenant la classe Pdf  qui elle contient toutes les caractéristiques d'un Pdf  
 

Code :
  1. package pdfFinder;
  3. import java.io.File;
  4. import java.io.IOException;
  5. import java.io.Serializable;
  6. import java.util.Date;
  8. import com.itextpdf.text.pdf.PdfReader;
  10. public class Pdf implements Serializable {
  11. private String nameFile;
  12. private long size;
  13. private String formatedSize;
  14. private int nbPages;
  15. private String path;
  16. private char version;
  17. private boolean isEncrypted;
  18. private Date lastModif;
  20. private PdfReader pdfReader;
  21. private File file;
  23. public Pdf(String path) throws IOException {
  24.  this.path = path;
  25.  file = new File(path);
  26.  nameFile = file.getName();
  27.  pdfReader = new PdfReader(nameFile);
  28.  nbPages = pdfReader.getNumberOfPages();
  29.  size = file.length();
  30.  formatedSize = getFormatedSize(size);
  31.  version = pdfReader.getPdfVersion();
  32.  isEncrypted = pdfReader.isEncrypted();
  33.  lastModif = new Date(file.lastModified());
  34. }
  37. public String getNameFile() {
  38.  return nameFile;
  39. }
  42. public long getSize() {
  43.  return size;
  44. }
  46. public String getFormatedSize (long size){
  47.  int temp;
  48.  size = size/1024;
  49.  if(size > 1000){
  50.   temp = (int)size;
  51.   temp = temp/1000;
  52.   if(size > 1000){
  53.    temp = (int)size;
  54.    temp = temp*1000;
  55.    return temp+" ko" ;
  56.   }
  57.   return temp+"Mo";
  58.  }
  60.  size = size*1000;
  61.  temp = (int)size;
  62.  temp = temp/1000;
  63.  return temp+"Bytes";
  65. }
  68. public int getNbPages() {
  69.  return nbPages;
  70. }
  73. public String getPath() {
  74.  return path;
  75. }
  78. public char getVersion() {
  79.  return version;
  80. }
  83. public boolean getIsEncrypted() {
  84.  return isEncrypted;
  85. }
  88. public Date getLastModif() {
  89.  return lastModif;
  90. }
  93. public PdfReader getPdfReader() {
  94.  return pdfReader;
  95. }
  97. public String toString(){
  98.  return "\n\tname = " + nameFile + "\n\tsize = " + formatedSize
  99.    + "\n\tnumber of pages = " + nbPages + "\n\tpath = " + path
  100.    + "\n\tversion = " + version + "\n\tencrypted = " + isEncrypted
  101.    + "\n\tlast modification = " + lastModif;
  102. }
  103. }

 
 
Le problème est qu'il m'indique  une aray out of bouds exeception a la ligne 66 dans le setData de la classe PdfFinder que je n'ai invoquée nul part et ceci se passe lorsque je clique sur le bouton start de ma fenêtre  
 
Je vous remercie d'avance pour votre aide :)
