# Java: Border Example

## Example -- A Titled, Etched, Empty Border around a Panel

Problem: Create a panel with 10 pixels of space around it, then an etched line with a title at the top left.
To do this, we need to create the etched border, then create a titled border from that. Then we put the titled border (which includes the etched border) together with the empty border to form a compound border. Then this compound border is added to the panel. Here are some ways to do this.

## Solution 1 - Inline code

You need to create the borders and combine them. You could add the border in one massive statement, but here it's broken down for simplicity.

    import javax.swing.border.*;
    . . .
    JPanel processPanel = new JPanel();
    Border etchedBdr = BorderFactory.createEtchedBorder();
    Border titledBdr = BorderFactory.createTitledBorder(etchedBdr, "Process");
    Border emptyBdr  = BorderFactory.createEmptyBorder(10,10,10,10);
    Border compoundBdr=BorderFactory.createCompoundBorder(titledBdr, emptyBdr);
    processPanel.setBorder(compoundBdr);

## Solution 2 - Utility method

It's common to use the same style of border on several panels. Write a utility method to do this, and save the method in your collection of handy methods.

1. There will be a consistent border style.
2. Changes will be made consistently.
3. The initial extra writing is repaid with only two calls.

This example creates the same border as above.

    import javax.swing.border.*;
    . . .
    // We can do this because the same border object can be reused.
        static final Border empty10Border = BorderFactory.createEmptyBorder(10,10,10,10);
        static final Border etchedBorder  = BorderFactory.createEtchedBorder();
    . . .
    public static Border myTitledBorder(String title) {
        return BorderFactory.createCompoundBorder(
                   BorderFactory.createTitledBorder(etchedBorder, title),
                   empty10Border);
    }//end myTitledBorder
    . . .
        JPanel processPanel = new JPanel();
        processPanel.setBorder(myTitledBorder("Process"));
