Question

I need some help parsing a string that is input to one that is later cleaned and output.

e.g.

String str = " tHis  strIng is  rEalLy mEssy  "

and what I need to do is have it parsed from that to look like this:

"ThisStringIsReallyMessy"

so I basically need to clean it up then set only the first letter of every word to capitals, without having it break in case someone uses numbers.

Answer 1

String[] tokens = " tHis  strIng is  rEalLy mEssy  ".split(" ");
StringBuilder result = new StringBuilder();
for(String token : tokens) {
    if(!token.isEmpty()) {
        result.append(token.substring(0, 1).toUpperCase()).append(token.substring(1).toLowerCase());
     }
}
System.out.println(result.toString()); // ThisStringIsReallyMessy
