Convert an string in title/proper case in apex

You can use below code snippet to convert any string in title/proper case.

Code Snippet:

 public String toTitleCase(String phrase){
    String titlePhrase = '';
    //a set of words that should always (or at least, almost always) be in lower case when in Title Case    
    Set<String> forceLower = new Set<String>{'is', 'of', 'the', 'for', 'and', 'a', 'to', 'at' ,'an', 'but', 'if', 'or', 'nor'};        
        if(phrase != null && phrase.length() > 0){
            String[] splitPhrase = phrase.trim().split(' ');            
            for(integer i = 0; i < splitPhrase.size(); i++){
                if(!forceLower.contains(splitPhrase[i].toLowerCase()) || i == 0 || i == (splitPhrase.size()-1) ){
                    titlePhrase += (splitPhrase[i].substring(0,1).toUpperCase())+(splitPhrase[i].substring(1).toLowerCase())+' ';
                }
                else{
                    titlePhrase += splitPhrase[i].toLowerCase()+' ';
                }
            }
        }
    return titlePhrase.trim();
 }
