You should be able to do that using a Border as well, just a slightly 
more complicated one.  You can use a CompoundBorder to combine two 
borders.  By doing this multiple times, you can create almost any effect 
you want.  Note that you can re-use the Border objects -- the same 
LineBorder is used each time.

    Border line = BorderFactory.createLineBorder( 
	Color.black, lineWidth );
    Border space = BorderFactory.createEmptyBorder( 
        spaceWidth, spaceWidth, spaceWidth, spaceWidth );
    Border border = line;
    for ( int i = 1;  i < count;  ++ i ) {
         border = new CompoundBorder( border, space );
         border = new CompoundBorder( border, line );
    }
    component.setBorder( border );

This does use a number of Border objects, but it is really not that 
expensive, and you don't have to write any painting code.

If you really want to do your own drawing code, then you could create 
your own Border class, say a MultiLineBorder.  You only need to implement 
three methods for the Border interface.  Two of them should be trivial, 
and the third would just entail the paint code that you are writing.  
Then you would be able to easily re-use your drawing code with any 
component.
