Issue with creating multiple checkbox on a fly

I am trying to read all the file name from a specific folder and trying to create multiple checkbox in JFrame with the same name. So, if there are 5 files in the folder, application should show 5 checkboxes in the frame.

Here is my code.

    JFrame frame = new JFrame();
    File folder = new File("C://Tests");
    File[] listOfFiles = folder.listFiles();

        for (int i = 0; i < listOfFiles.length; i++) {
          if (listOfFiles[i].isFile()) {
            System.out.println("File " + listOfFiles[i].getName());
          } else if (listOfFiles[i].isDirectory()) {
            System.out.println("Directory " + listOfFiles[i].getName());
          }
          JCheckBox checkbox[i] = new JCheckBox(listOfFiles[i].getName());

        }

But I am getting error "Type mismatch: cannot convert from JCheckBox to JCheckBox[]". Can someone please tell me what am I doing incorrect ?

Appreciate any help. Thanks
