Need to get "jButton2" information inside "jButton12"

Question

At present I am sending two parameters (readXMLfile, changeFilename) from the method "ReadFile" to the class "filesMove". But I need to send these two parameters (readXMLfile, changeFilename) from "private void jButton12ActionPerformed(java.awt.event.ActionEvent evt)". I am unable get "readXMLfile" inside "private void jButton12ActionPerformed(java.awt.event.ActionEvent evt)". Could anyone Please help me with this.
My code is:
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt)
     JFileChooser chooser=new JFileChooser();
     chooser.setCurrentDirectory(curfile);
     chooser.setMultiSelectionEnabled(true);
     int state=chooser.showOpenDialog(null);
     File[] files=chooser.getSelectedFiles();
     String[] filenames=getFilenames(files);
     for(int i=0;i<filenames.length;i++)
          try
               ReadFile(curfile,filenames);
          catch(IOException ex)
               ex.printStackTrace();
File curfile=new File("D:/sample/");
private String[] getFilenames(File[] files)
     String[] filenames=null;
     int numFiles=files.length;
     if(files.length>0)
          filenames=new String[numFiles];
          for(int i=0; i<numFiles;i++)
               filenames[i]=files[i].getName();
     return filenames;
private void ReadFile(File readDir, String XMLfile) throws IOException
     File readXMLfile=new File(readDir,XMLfile);
     //output: readXMLfile: D:\sample\ABACE___.ABC
     //output: readXMLfile: D:\sample\ABACE___.DEF
     String changeFilename=jTextField1.getText();
     File dstfile=new File("C:/temp/sample");
     if(!dstfile.exists())
          dstfile.mkdirs();
     if(!rename.equals(""))
          //I am passing (readXMLfile,changeFilename) from here
          filesMove fm=new filesMove();
          try
               fm.copyDirectory1(readXMLfile,changeFilename);
          catch(IOException e)
               System.out.println(e.getMessage());
private void jButton12ActionPerformed(java.awt.event.ActionEvent evt)
     String changeFilename="";
     if((!(jTextField2.getText().toString().equals("")))&&(!(jComboBox1.getSelectedItem().toString().equals("")))&&(!(jComboBox2.getSelectedItem().toString().equals("")))&&(!(jComboBox3.getSelectedItem().toString().equals("")))&&(!(jComboBox4.getSelectedItem().toString().equals("")))&&(!(jComboBox5.getSelectedItem().toString().equals(""))))
          String jTextField2Txt=jTextField2.getText().toString();
          String jComboBox1Text=jComboBox1.getSelectedItem().toString();
          String jComboBox2Text=jComboBox2.getSelectedItem().toString();
          String jComboBox3Text=jComboBox3.getSelectedItem().toString();
          String jComboBox4Text=jComboBox4.getSelectedItem().toString();
          String jComboBox5Text=jComboBox5.getSelectedItem().toString();          
          changeFilename=jTextField2Text+jComboBox1Text+jComboBox2Text+jComboBox3Text+jComboBox4Text+jComboBox5Text;
          jTextField1.setText(changeFilename);
          /* But I need to pass (readXMLfile,changeFilename) from here
          filesMove fm=new filesMove();
          try
               fm.copyDirectory1(readXMLfile,changeFilename);
          catch(IOException e)
               System.out.println(e.getMessage());

My code is:
public class Main extends javax.swing.JFrame
     /** Creates new form Main */
     private File readXMLfile;
     private void jButton2ActionPerformed(java.awt.event.ActionEvent evt)
          readXMLfile=new File(readDir,fileName);     
          //output: readXMLfile: D:\sample\ABACE___.ABC
          //output: readXMLfile: D:\sample\ABACE___.DEF
          //output: readXMLfile: D:\sample\ABACE___.GHI
     private void jButton12ActionPerformed(java.awt.event.ActionEvent evt)
          else if(!(jComboBox5.getSelectedItem().toString().equals("")))
               String jComboBox5Txt=jComboBox5.getSelectedItem().toString();
               String jComboBox5Text=jComboBox5Txt.substring(0,1);
               changeFilename=jComboBox1Text+jTextField2Text+jComboBox5Text;
          //Its outputting only the last selected file
          System.out.println("readXMLfile: +readXMLfile);     
          //output: readXMLfile: D:\sample\ABACE___.GHI
          String rename=changeFilename+"8a";
          String renameSub=rename.substring(0,3);
          filesMove fm=new filesMove();
          try
               fm.copyDirectory1(readXMLfile,rename,renameSub);
          catch(IOException e)
               System.out.println(e.getMessage());
