Problem converting String to Title Case

Hello people,

Please could someone slove this for me. I have a method that is passed a string from a JTextfield on my GUI. Now I want to take that string and convert the first char and any char after whitespace into Capitals.

So for example  'springfield house' would become 'Springfield House'.

Below is what I have but the compiler does not want like it one bit!!!!!

public void setAddress(String newAddress){
       
for (int count = 1; count < newAddress.length(); count++){

             if (newAddress.charAt(x).equals(" "))              //If char equal a blank space
                   newAddress.ChartAt(x++).toUpperCase();
             else
                   count++; }
        address = newAddress;}                //The variable ;address ;(String)

Can anyone help. The more simple the answer the better!

Shame String has'nt got a 'toTitleCase' method!

Thanks

Beam

Quick and dirty and untested

  public static String toTitleCase(String s) {
    StringBuffer sb = new StringBuffer(s.trim());
    for(int i = 0;i < sb.length();i++) {
      char c = sb.charAt(i);
      if (c == ' ')
        sb.setCharAt(i + 1, Character.toUpperCase(sb.charAt(i + 1)));
    }
    return sb.toString();
  }


You might want to move the first char to upper case come what may...

try:

StringBuffer temp = new StringBuffer(newAddress);
for (int count = 0; count < temp.length(); count++)
{
   char c = temp.chatAt(count);
   if ((count==0 || temp.charAt(count-1)==' ') && !Character.isWhitespace(c))
   {
        temp.setCharAt(Character.toUpperCase(c));
   }
}
address = temp.toString();

If that is the case (not sure what the 'rules' are) then do

sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));

before returning

it's specified in the question :)

public void setAddress(String newAddress)
{        
  StringBuffer temp = new StringBuffer(newAddress);
  for (int count = 0; count < temp.length(); count++)
  {
     char c = temp.charAt(count);
     if ((count==0 || temp.charAt(count-1)==' ') && !Character.isWhitespace(c))
     {
          temp.setCharAt(count, Character.toUpperCase(c));
     }

Objects, I tried your version first but it throws the  syntax error ' StringBuffer can not be applied to Char'  for the line  'temp.setCharAt(Character.toUpperCase(c));' ????

About to try yours CEHJ.

That was a typo, it's fixed in the 2nd code I posted.

I think CEHJ's will crash if you pass it a blank string, also wasn't sure if you wanted the leading and trailing spaces trimmed.
Change last line to:

address = temp.toString().trim();

if you do.

And yours will crash if you pass it a null String ;-)

good point:

public void setAddress(String newAddress)
{
  if (newAddress==null)
  {
      address = null;  //or u might want to set it to blank
  }
  else
  {        
    StringBuffer temp = new StringBuffer(newAddress);
    for (int count = 0; count < temp.length(); count++)
    {
       char c = temp.charAt(count);
       if ((count==0 || temp.charAt(count-1)==' ') && !Character.isWhitespace(c))
       {
            temp.setCharAt(count, Character.toUpperCase(c));
       }
    }
    address = temp.toString();
  }
}
