convernting to camel caps
Roedy Green
Here is how you might automatically convert lower case words to camel
cap form. I use it to generate a first cut at a web site name from a
lower case URL. See the results at
http://mindprod.com/jgloss/minorhassle.html
// converting a lower case word to camel caps.
/**
* capitalise common words embedded in name, and remove dashes,
marking the spots with caps.
*
* @param name name to camel-capitalise

private static String toCamel( String name )
{
return toCamelCaps( toCamelDashes( name ) );

if ( c == '-' )
{
// drop the -, append the following char capitalised
final int next = i + 1;
if ( next < name.length() )

sb.append( Character.toUpperCase( name.charAt(
next ) ) );
// we processed one more char than usual
i++;

{
sb.append( c );

return sb.toString();
