Este artigo demonstra como "normalizar" os espaços em branco dentro de uma string.

Um simples método para normalizar strings com múltiplos espaços em branco( substituindo-os por espaço simples). Por exemplo para normalizar o string:

"     Normalize    todos  os espaços em branco  "
to:
" Normalize todos os espaços em branco ".

String normalizeWhitespaces(String s)
{
StringBuffer res = new StringBuffer();
 
int prevIndex = 0;
 
int currIndex = -1;
 
int stringLength = s.length();
 
String searchString = " ";
 
while((currIndex = s.indexOf(searchString, currIndex + 1)) >= 0)
{
res.append(s.substring(prevIndex, currIndex + 1));
 
while(currIndex < stringLength && s.charAt(currIndex) == ' ')
{
currIndex++;
}
 
prevIndex = currIndex;
}
res.append(s.substring(prevIndex));
 
return res.toString();
}
