Questa è la classe dove ho il main

codice:
package mySplitProva; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; import java.io.File; import javax.swing.JFileChooser; import javax.swing.filechooser.FileFilter; import java.io.*; public class SplitJFrame extends javax.swing.JFrame { /** Creates new form SplitJFrame */ public SplitJFrame() { initComponents(); jSplitPane1.setOneTouchExpandable(true); } @SuppressWarnings("unchecked") private void jFileReaderActionPerformed(java.awt.event.ActionEvent evt) { JFileChooser fileChooser = new JFileChooser(); fileChooser.setFileFilter(new TxtFileFilter()); int returnVal = fileChooser.showOpenDialog(this); if(returnVal == JFileChooser.APPROVE_OPTION){ File myFile = fileChooser.getSelectedFile(); FileImport obj1 = new FileImport(myFile); jTotalRowsTextField.setText(String.valueOf(obj1.numberOfLines())); System.out.println(obj1.checkIsFile()); System.out.println(obj1.numberOfLines()); obj1.importToArray(); obj1.printArray(); System.out.println("--------------------------------------"); obj1.buildDataArray(obj1.getArray()); obj1.printDataArray(); } } private class TxtFileFilter extends FileFilter{ public boolean accept(File file){ if(file.isDirectory()) return true; String fname = file.getName(); return fname.endsWith("txt"); } public String getDescription(){ return "txt file"; } } public static void main(String args[]) { try{ UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch(UnsupportedLookAndFeelException e){ //handle exception } catch(ClassNotFoundException e){ //handle exception } catch(InstantiationException e){ //handle exception } catch(IllegalAccessException e){ //handle exception } java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new SplitJFrame().setVisible(true); } }); }
Mentre questa è la classe dove ho i metodi


codice:
package mySplitProva; import java.io.*; //import java.util.StringTokenizer; import java.util.*; import java.text.SimpleDateFormat; public class FileImport { private File fileToImport; private Date[] dateArray; private double[][] dataArray; public FileImport(File myFile) { fileToImport = myFile; dateArray = new Date[numberOfLines()];//Array for date(calendar) dataArray = new double[numberOfLines()][6];//Array for double data }//constructor for fileToImport field int lines = 0; String[][]bin; public boolean checkIsFile(){ return fileToImport.isFile(); } public int numberOfLines(){ lines = 0; if(checkIsFile()){ try{ FileReader fr = new FileReader(fileToImport); BufferedReader br = new BufferedReader(fr); while((br.readLine()!=null)){ lines++; }//end while loop br.close(); }catch(Exception e){ System.out.println(e); } } else{ System.out.println("There is no file to import"); } return lines; }//returns number of lines in a txt file public void importToArray(){ int rows = 0; bin = new String[numberOfLines()][6]; try { FileReader fr = new FileReader(fileToImport); BufferedReader br = new BufferedReader(fr); String line = null; while((line = br.readLine())!= null){ StringTokenizer stk = new StringTokenizer(line, ","); while(stk.hasMoreTokens()){ for (int cls = 0;cls<6; cls++){ bin[rows][cls]= stk.nextToken(); } rows++; }//end inner while loop }//end outer while loop br.close(); }//end try catch(Exception e){ System.out.println(e); } }//import data to bin array public void printArray(){ for(int i =0;i<bin.length; i++){ System.out.printf("%s ", i); for(int j =0;j<bin[i].length; j++){ System.out.printf("%s ", bin[i][j]); } System.out.println(""); }//end for loop }//print contents of bin array public String[][] getArray(){ return bin; }//return bin array public void buildDateArray(String[][]d) { SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");//set date format here; for(int i=0;i<d.length; i++){ for(int j = 0;j<d[i].length; j++){ if(j==0){ try{ Date newDate = (Date)sdf.parse(d[i][0]);//parse first column to Date dateArray[i] = newDate; }//end try catch(Exception e){ System.out.println(e); }//end catch } } }//end for loops } public void buildDataArray(String[][]d){ for(int i=0;i<d.length;i++){ for(int j=0;j<d[i].length; j++){ switch(j){ case 0: dataArray[i][j]=0; break; case 1: dataArray[i][j]=new Double(d[i][j]); break; case 2: dataArray[i][j]=new Double(d[i][j]); break; case 3: dataArray[i][j]=new Double(d[i][j]); break; case 4: dataArray[i][j]=new Double(d[i][j]); break; case 5: dataArray[i][j]=new Double(d[i][j]); break; }//end switch } }//end for loops } public void printDataArray(){ for(int i=0;i<dataArray.length;i++){ for(int j=0;j<dataArray[i].length;j++){ System.out.printf("%s ", dataArray[i][j]); } System.out.println(""); } } public void printDateArray(){ for(int i=0;i<dateArray.length;i++){ System.out.println(dateArray[i]); } } }
Potrebbe essere una soluzione quella di abbinare un listener differente ad ogni RadioButton?

Grazie

PS spero che l'indentazione sia venuta correttamente questa volta...
PS2 evidentemente sbaglio qualcosa perchè nonostante uso CODE per inserire il codice e chiudo il tag, mi stampa tutto su una riga.
