Compiling Error... Found: Class Expected: Value

Question

Hello, I am writing a GUI with a "join file" feature.
So far, I load my files (multiple files enabled):
private void loadFile()
             JFileChooser fc = new JFileChooser();
              fc.setMultiSelectionEnabled(true);
            int returnVal = fc.showOpenDialog(MyFrame.this);
               if (returnVal == JFileChooser.APPROVE_OPTION)
                   File[] files = fc.getSelectedFiles();
       }I join them by adding them into a vector (not sure if there's a better way?):
public void joinFiles(File[] files)
               Vector v = new Vector();
               for (int i = 0; i<files.length; i++)
                   String fileName = new String(files.toString());
               String line;
                    try
                         BufferedReader in = new BufferedReader(new FileReader(fileName));
                         if ( !in.ready() ) throw new IOException();
                              while ( (line = in.readLine() ) != null)
               v.add(line);
                    in.close();
                    catch (IOException e)
                    System.out.println(e);
Then, as I have a GUI, I have menu item actions set up as follows:
public void actionPerformed(ActionEvent e){
          if(e.getSource() == load){
               loadFile();
          if(e.getSource() == join){
               joinFiles(File[] files);
          }This generates the error:
fileManipulator.java:93: '.class' expected
joinFiles(File[] files);
^
fileManipulator.java:93: ')' expected
joinFiles(File[] files);
^
fileManipulator.java:93: unexpected type
required: value
found : class
joinFiles(File[] files);
^
Help me please!!

public class FileStuff {
    File [] fileArray;  //Declare as instance variable.
private void loadFile()
    JFileChooser fc = new JFileChooser();
    fc.setMultiSelectionEnabled(true);
    int returnVal = fc.showOpenDialog(MyFrame.this);
    if (returnVal == JFileChooser.APPROVE_OPTION)
        //files IS NOT ACCESSIBLE OUTSIDE THIS "if" statement.
        File[] files = fc.getSelectedFiles();      // DELETE THIS
        fileArray = fc.getSelectedFiles();    // ADD THIS !!!!!!!
public void joinFiles(File [] files)
{  .. no change ..}
public void actionPerformed(ActionEvent e)
{  .. no change to "loadFile" part ..;
   if (e.getSource() = join)
      joinFiles(fileArray);
}
