I imagine you could use substring   and toUpperCase   to pull out the first character  uppercase it  and then replace the first character of your string with the result   myString    cheeseburger   firstChar   myString substring  0  1           c  firstChar toUpperCase    tail   myString substring  1           heeseburger  myString   firstChar   tail     myString     Cheeseburger    I think that should work for you   Another thing to consider is that if this data is being displayed  you can add a class to its container that has the CSS property  text-transform  capitalize
