How to upper case every first letter of word in a string?

Question

I have a string: "hello good old world" and i want to upper case every first letter of every word, not the whole string with .toUpperCase(). Is there an existing java helper which does the job?

Answer 1

i dont know if there is a function but this would do the job in case there is no exsiting one:

String s = "here are a bunch of words";

final StringBuilder result = new StringBuilder(s.length());
String[] words = s.split("\\s");
for(int i=0,l=words.length;i<l;++i) {
  if(i>0) result.append(" ");      
  result.append(Character.toUpperCase(words[i].charAt(0)))
        .append(words[i].substring(1));

}

Answer 2

Have a look at ACL WordUtils.

Also you can take a look into [StringUtils][1] library. It has a bunch of cool stuff.

Answer 5

public String UpperCaseWords(String line) { line = line.trim().toLowerCase(); String data[] = line.split("\s"); line = ""; for(int i =0;i< data.length;i++) { if(data[i].length()>1) line = line + data[i].substring(0,1).toUpperCase()+data[i].substring(1)+" "; else line = line + data[i].toUpperCase(); } return line.trim(); }
