Detect if Swing is Installed

Sometimes it is useful to know if Swing is installed in a Java environment or not, especially if you are dealing with browsers. You can simply try to create a Swing component, as in:
 
try 
{
    javax.swing.JButton jBtn = new javax.swing.JButton
("a button"); System.out.println("Swing is installed"); jBtn = null; } catch(NoClassDefFoundError e) { System.out.println("Swing is not here,
you must download or install it"); }
