Setting radio buttons to a background

Question

I was trying to set Radio Button to a background in order to allow the user to select.

Here is the code ..

public class FirstWindow extends JFrame {

    private JTextField search;
    private JRadioButton author,title,both;
    private ButtonGroup grp;

    public FirstWindow() {
       super("My App");
       setLayout(new BorderLayout());

    JLabel backGround = new JLabel(new ImageIcon("C:\\Users\\Kareem Abdo\\Desktop\\3.Jpg"));
    backGround.setLayout(null);
    add(backGround);

    search = new JTextField("Search...");
    search.setFont(new Font("Arial",Font.PLAIN,16));
    search.setSize(150, 30);
    search.setLocation(20, 20);
    backGround.add(search);

    author = new JRadioButton("Author",true);
    author.setLocation(20, 25);
    backGround.add(author);

    title = new JRadioButton("Title",false);
    title.setLocation(25, 25);
    backGround.add(title);

    both = new JRadioButton("Both",false);
    both.setLocation(250, 250);
    backGround.add(both);

    grp = new ButtonGroup();
    grp.add(author);
    grp.add(title);
    grp.add(both);

But the radio buttons doesn't appear on the screen!

1) For better help sooner, post an [SSCCE](http://sscce.org/). 2) Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or combinations of them, along with layout padding & borders for white space. 3) Don't extend frame or other top level containers. Instead create & use an instance of one. — Andrew Thompson, Jul 13 '13 at 09:59
You are specifying only `location`, but no size for `JRadioButton`. You need to specify that too, but since its a completely wrong approach you taking, I won't say a word after this :-) — nIcE cOw, Jul 13 '13 at 10:17
Please have a look at this related [example (2nd code)](http://stackoverflow.com/a/11428289/1057230) — nIcE cOw, Jul 13 '13 at 13:13

JLabel (JLabel backGround = new JLabel) haven't implemented any LayoutManager, then you have to set the proper one, otherwise any JComponent added to JLabel isn't visible
maybe better could be start with Image (BufferedImage) painted in paintComponent to the JPanel (pre_implemented FlowLayout in API)

i had set the layout of backGround to null in order to be able to sort the components as I want, I don't want the layout manager to sort them – Kareem Abdo Jul 13 '13 at 10:18

*"I don't want the layout manager to sort them"* Then expect all the types of problems currently being seen, & stop bothering us. If you had the smarts to layout the components, you could put that logic in a custom layout manager (tip: this question indicates you don't). – Andrew Thompson Jul 13 '13 at 11:17
