Question

在Java中，你如何转换它：

little bo peep HAS LOST HER SHEEP And Doesn't Know WHERE to Find them

到此：

Little Bo Peep Has Lost Her Sheep And Doesn't Know Where To Find Them

Answer 1

来自commons lang的

WordUtils.capitalizeFully(String input)

Answer 2

public static void main(String[] args) {

  String str = "little bo peep HAS LOST HER SHEEP And Doesn't Know WHERE to Find them";
  str = str.toLowerCase();
  final StringTokenizer st = new StringTokenizer(str, " ");
  final StringBuilder sb = new StringBuilder();

  while (st.hasMoreTokens()) {
   String token = st.nextToken();
   sb.append(Character.toUpperCase(token.charAt(0))
     + token.substring(1) + " ");
  }

  System.out.println(sb.toString().trim());
 }

Answer 3

或普通拆分版：

public static String capWords(String s) {
    if (s == null && s.isEmpty()) {
        return s;
    } else {
        StringBuilder sb = new StringBuilder();
        for (String token : s.split(" ")) {
            if (token.isEmpty()) {
                if (sb.length() > 0) {
                    sb.append(" ");
                }
            } else {
                if (sb.length() > 0) {
                    sb.append(" ");
                }
                sb.append(Character.toUpperCase(token.charAt(0)));
                if (token.length() > 1) {
                    sb.append(token.substring(1).toLowerCase());
                }
            }
        }
        return sb.toString();
    }
}

注意：此版本还会修剪前导/尾随空格（可能需要也可能不需要）

Answer 4

    private static String capitalize(String s){
        String str = s.toLowerCase();
        char[] c = str.toCharArray();

        c[0] = Character.toUpperCase(c[0]);
        return new String(c);
    }

    private static String format(String s){
        String[] splitted = s.split(" ");
        StringBuffer sb = new StringBuffer();

        for(int i=0, l = splitted.length; i < l; i++){
            if(splitted[i].trim().length() != 0){
                 sb.append(capitalize(splitted[i]) + " ");
            }

            if(i != l-1){
                 sb.append(" ");
            }
        }

        return sb.toString();
    }


    public static void main(String... args){

        System.out.println(format("little bo peep HAS LOST HER SHEEP And Doesn't Know WHERE to Find them"));

    }

                    i=i+1;
                }
                else 
                    res=res+Character.toLowerCase(s.charAt(i));
        }
        System.out.println(res);
    }
    catch(Exception e){}
