I don't know if I've clearly understood your problem, but if you want to normalize multiple whitespaces, replacing them with a single whitespace, you can try this code snippet:

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();
}
