Splitting Full Name

I have string for instance, "John Daws Black" splitted with spaces and I need to split them to two parts so that there will be name part like "John Daws" and surname part like "Black". However the front name part can be any length like "John Erich Daws Black". My code can get the last part:

public String getSurname(String fullName){
    String part = "";
     for (String retval: fullName.split(" "))
         part = retval;
         return part;
}

But I don't know how to get the front part.

Below methods worked for me. It takes into account that if middle name is present, then that gets included in first name:

private static String getFirstName(String fullName) {
        int index = fullName.lastIndexOf(" ");
        if (index > -1) {
            return fullName.substring(0, index);
        }
        return fullName;
    }

    private static String getLastName(String fullName) {
        int index = fullName.lastIndexOf(" ");
        if (index > -1) {
            return fullName.substring(index + 1 , fullName.length());
        }
        return "";
    }

Just a re-write for Andreas answer above but using sperate methods to get first and last name

    public static String get_first_name(String full_name)
    {
      int last_space_index = full_name.lastIndexOf(' ');
      if (last_space_index == -1) // single name
          return full_name;
      else
          return full_name.substring(0, last_space_index);
    }

    public static String get_last_name(String full_name)
    {
      int last_space_index = full_name.lastIndexOf(' ');
      if (last_space_index == -1) // single name
          return null;
      else
          return full_name.substring(last_space_index + 1);
    }

Here's a solution I've used before that accounts for suffixes too.. ( 3 chars at the end ) 

/**
 * Get First and Last Name : Convenience Method to Extract the First and Last Name.
 *
 * @param fullName
 *
 * @return Map with the first and last names.
 */
public static Map<String, String> getFirstAndLastName(String fullName) {

    Map<String, String> firstAndLastName = new HashMap<>();

    if (StringUtils.isEmpty(fullName)) {
        throw new RuntimeException("Name Cannot Be Empty.");
    }

    String[] nameParts = fullName.trim().split(" ");

    /*
     * Remove Name Suffixes.
     */
    if (nameParts.length > 2 && nameParts[nameParts.length - 1].length() <= 3) {
        nameParts = Arrays.copyOf(nameParts, nameParts.length - 1);
    }

    if (nameParts.length == 2) {
        firstAndLastName.put("firstName", nameParts[0]);
        firstAndLastName.put("lastName", nameParts[1]);
    }

    if (nameParts.length > 2) {
        firstAndLastName.put("firstName", nameParts[0]);
        firstAndLastName.put("lastName", nameParts[nameParts.length - 1]);
    }

    return firstAndLastName;

}

Try this :

String[] name = fullname.split(" ")
if(name.size > 1){
    surName = name[name.length - 1]
    for (element=0; element<(name.length - 1); element++){
        if (element == (name.length - 1)) 
            firstName = firstName+name[element]
        else 
            firstName = firstName+name[element]+" "
    }
}
else 
    firstName = name[0]
