Class Cast Execption when Trying to Add Object array as Component in Java Swing

Question

I have a JFrame which has many LayredPane's and those LayerdPane's has many JPanel's in it.

i have more than 50 JPanel's in the a Single Layered Pane where i want to switch the panels according to my JCombobox selected index.

so i have copied all the Panel Variable names as String Array and pass the Panel Variable name as per the JCombobox index number name.

Object Array with Panel Variable Names

public Object panelNames[]={
    "clinicalPathalogyReport",
    "clinicalHaematologyReport",
    "clinicalSerologyReport",
    "clinicalSerologyReport",
    "clinicalSerologyReport",
    "clinicalSerologyReport",
    "clinicalBiochemistryReport",
    "clinicalHaemotologyReport",
    "clinicalBiochemistryReport1",
    "clinicalBiochemistryReport2",
    "clinicalBiochemistryReport3",
    "clinicalHaemotologyReport2",
    "urinePregnancyTest",
    "completeBloodPicture",
    "clinicalPathalogyReport1",
    "clinicalBiochemistryReport4",
    "clinicalBiochemistryReport5"};

So i want to pass the Variable name with my Selected index

so here is my source code to perform action

int i=uniqueTests.getSelectedIndex();

                ltlayeredPane.removeAll();
                ltlayeredPane.add((Component)panelNames[i]);
                ltlayeredPane.repaint();
                ltlayeredPane.revalidate();

But i am having Class Cast Exception

The elements of the array `panelNames` are `String` objects. You are trying to cast a `String` object to `Component`. Since a `String` is not a `Component`, you will get a `ClassCastException`. — Jesper, Jul 27 '17 at 10:51
is there any way to over come this, because i have more JPanels — Intact Abode, Jul 27 '17 at 10:52
You can create an array (or list) of Components `public Components[] panels` and add the actual components to that array. — OH GOD SPIDERS, Jul 27 '17 at 10:53
