How to capitalize the first letter of word in a string using Java?

If you only want to capitalize the first letter of a string named input and leave the rest alone:

Capitalizing the first character of a string - Java

It might be easier just to assume that the first letter is always lowercase, then you don't need any checks:

String capitol   = Character.toString(s.charAt(0)).toUpperCase();
String newString = capitol + s.substring(1,x);

Code looks fine, just make some changes

String newWord = letter1.toUpperCase()
                + word.substring(1, word.length() - 1)
                + lastletter.toUpperCase();

First Letter - letter1.toUpperCase()

Middle String - word.substring(1, word.length() - 1)

Last Letter - lastletter.toUpperCase();

output
