JLabel is not showing up?

I initially created a JLabel object and added it to JFrame but the content was not showing up.I found a post on stackoverflow using container to display JLabel on JFrame.I tried that too but even that didn't work.I went through a lot of posts but I couldn't find any solution.The button is being displayed but Jlabel is no where to be seen!

Dimension s=new Dimension(400,400);
    JFrame l=new JFrame();
    l.setSize(s);
    l.setResizable(true);
    Dimension s1=new Dimension(100,100);
    Container me=new Container();
    JLabel kingsman=new JLabel ("kingsman");

    me.add(kingsman);
    l.add(me);

    JButton p=new JButton("Goal"); 
    p.setSize(s1);
    l.add(p);
    //l.pack();
    l.setVisible(true);

There is one more problem.When I call pack() function,Jframe is getting reduced to a small window instead of the dimension that I have mentioned. Please Help!

The reason the label does not show up is that the content pane of a JFrame uses a BorderLayout as its LayoutManager. When you call l.add(me) and then l.add(p) you are effectively replacing the Container instance with the button. Try changing you Container to a JPanel, add both label and button components to that and then add it to your frame's content pane. Read up on Layout Managers, too.

The following example shows a JPanel containing a JLabel and JButton arranged using the JPanel's default LayoutManager of FlowLayout.

    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JPanel content = new JPanel();
    content.add(new JLabel("A Label"));
    content.add(new JButton("A Button"));

    frame.add(content);
    frame.pack();
    frame.setVisible(true);
