How to set just the left coordinates and the width of a JPanel?

I'd like to set the left-co-ordinates and the width of a panel that's inside another panel.

innerPanel.setBounds(/* expects a rectangle that 
         specifies y and height, which I would not like to set */);

setBounds expects me to specify the y coordinate and the height as well, which I don't want to set because I'd like to stack things up inside this panel vertically, like a Stack Layout (an old layout that was present in VJ++, the Microsoft copy of Java) or a GridLayout(0, 1).

See the picture below please.

enter image description here

Each of those books are a panel inside a larger panel. I want them to have some space on the left and some on the right and then I want to word-wrap the descriptions.

How do I set just the left coordinate and the width without touching the other two variables?

As per Andrew Thompson's suggestion, I created an empty border around the panel that contains all the books and I've solved the problem of defining a padding or margin around the edges of the container.

public class BookRecommendationsContentPanel extends JPanel {

    public BookRecommendationsContentPanel(JLabel lblStatus) {
        super();

        ...

        this.setBorder(new EmptyBorder(20, 20, 10, 20));
    }

    public void AddBook(Book book) {

        JPanel pnlBook = new JPanel();
        ...
        this.add(pnlBook);
    }
}

It now looks a lot better.

Only, now I have some more things to deal with such as:

  1. Word-wrapping the book descriptions;
  2. Making the content panel scrollable; and
  3. Making sure the label height for the book name label is set so it doesn't clip the content.

But these are not the problems I mentioned in the question, so his suggestion solves my problem adequately.

If you are using any layout manager, setBounds() has no effect anyway. Just use setPreferredSize() to specify the width and height.

There is a good chance I have not understood your requirement fully. It would help if you put a picture of how you want the components to be displayed and then I could suggest the best layout to achieve that.
