Border border = BorderFactory.create…
Now we will code to create some kind of simple border as shown below.

Use matte border

Matte Border is a form that allows us to use color or image to create contour. It also gives us the size to the edge again. However when taking pictures, you should set the data size is -1 Meanwhile size will appear unchanged, not lost. Code examples,.

  private Border matteBorderColor;
  private Border matteBorderIcon;

  /**

   */
  private Border panelBorder = BorderFactory
      .createEmptyBorder(20, 20, 20, 20);

  public DemoMatteBorder() {
    createBorder();
    add(createContent());
    setDisplay();
  }

  private void setDisplay() {
    setTitle("Demo Matte Border");

    panel.setBorder(panelBorder);

    panel.add(createPaneBorder(matteBorderColor, "matte border with color"));
    if (matteBorderIcon != null) {
      panel.add(createPaneBorder(matteBorderIcon,
          "matte border with icon"));
    } else {
      panel.add(createPaneBorder(matteBorderColor, "don't found icon"));
    }

    return panel;
  }

  /**

  private JPanel createPaneBorder(Border border, String content) {
    JPanel panel = new JPanel(new BorderLayout());
    panel.setBorder(border);

Using the title border

Title Border is a form titled border. You can put the title in the left, right, between, on the lower border,… Also you can set the border as a border in certain forms that have been created, otherwise the default blue border will be blurred.

    JPanel panel = new JPanel(new GridLayout(6, 1, 10, 10));
    panel.setBorder(panelBorder);

    Border titleBorder;
    Border blueBorder = BorderFactory.createLineBorder(Color.BLUE);

    titleBorder = BorderFactory.createTitledBorder("title");
    panel.add(createPaneBorder(titleBorder, "default title border"));

    titleBorder = BorderFactory.createTitledBorder(blueBorder, "title");
    panel.add(createPaneBorder(titleBorder, "title border with color blue"));

    titleBorder = BorderFactory.createTitledBorder(blueBorder, "title",
        TitledBorder.CENTER, TitledBorder.DEFAULT_POSITION);
    panel.add(createPaneBorder(titleBorder,
        "title border center just and default prsition"));

    titleBorder = BorderFactory.createTitledBorder(null, "title",
        TitledBorder.CENTER, TitledBorder.ABOVE_TOP);
    panel.add(createPaneBorder(titleBorder,
        "title border center just and above top"));

  private JPanel createPaneBorder(Border border, String content) {
    JPanel panel = new JPanel(new BorderLayout());
    panel.setBorder(border);
    JLabel lb = new JLabel(content, JLabel.CENTER);

    new DemoTitleBorder();
  }
}

public class DemoCompoundBorder extends JFrame {

	/** create border type */

	private Border lineBorder = BorderFactory.createLineBorder(Color.blue);

	private Border loweredBevel = BorderFactory.createLoweredBevelBorder();

	/**
	 * create border empty for JPanel contain content
	 */
	private Border panelBorder = BorderFactory
			.createEmptyBorder(20, 20, 20, 20);

	public DemoCompoundBorder() {

		setDisplay();
	}

	private void setDisplay() {

		setLocationRelativeTo(null);
		setVisible(true);
	}

	/**
	 * create JPanel contain six JPanel with borders
	 */
	private JPanel createContent() {
		JPanel panel = new JPanel(new GridLayout(3, 1, 10, 10));
		panel.setBorder(panelBorder);

		Border compound = BorderFactory.createCompoundBorder(raisedBevel,
				loweredBevel);
		panel.add(createPaneBorder(compound, "raisedBevel and loweredBevel"));

		compound = BorderFactory.createCompoundBorder(lineBorder, compound);
		panel.add(createPaneBorder(compound, "add lineBorder to compound"));

		Border titleBorder = BorderFactory.createTitledBorder(compound,
				"title", TitledBorder.CENTER, TitledBorder.DEFAULT_POSITION);
		panel.add(createPaneBorder(titleBorder, "title border with compound"));

		return panel;
	}

	/**
	 * create JPanel contain a border

	private JPanel createPaneBorder(Border border, String content) {

		panel.setBorder(border);
		JLabel lb = new JLabel(content, JLabel.CENTER);
		panel.add(lb);
		return panel;
	}
