capitals

how can i capitalize the first letter of a string? splitting the string, giving UpperCase to the first letter and unite the two substrings? so how i do that

Code:

String s = "hello world";
String[] strs = s.split("\\s");
for(int j = 0; j < strs.length; j++) {
    String firstLetter = String.valueOf(strs[j].charAt(0));
    firstLetter = firstLetter.toUpperCase();
    strs[j] = firstLetter + strs[j].substring(1);
}
for(int j = 0; j < strs.length; j++)
    System.out.println(strs[j]);
