Split string with three words

What is the best way to split a string containing three words?

My code looks like this right now (see below for updated code):

BufferedReader infile = new BufferedReader(new FileReader("file.txt"));

        String line;
        int i = 0;

        while ((line = infile.readLine()) != null) {
            String first, second, last;
            //Split line into first, second and last (word)

            //Do something with words (no help needed)
            i++;
        }

Here is the full file.txt:

New code as @Pshemo suggested:

public String load() {
    try {
        Scanner scanner = new Scanner(new File("reg.txt"));

        while (scanner.hasNextLine()) {
            String firstname = scanner.next();
            String lastname = scanner.next();
            String number = scanner.next();
            list.add(new Entry(firstname, lastname, number));
        }
        msg = "The file reg.txt has been opened";
        return msg;
    } catch (NumberFormatException ne) {
            msg = ("Can't find reg.txt");
            return msg;
    } catch (IOException ie) {
            msg = ("Can't find reg.txt");
            return msg;
    }
}

I receive multiple errors, what's wrong?

Assuming that each line always contains exactly three words instead of split you can simply use Scanners method next three times for each line. 

Scanner scanner = new Scanner(new File("file.txt"));
int i = 0;
while (scanner.hasNextLine()) {
    String first = scanner.next();
    String second = scanner.next();
    String last = scanner.next();
    //System.out.println(first+": "+second+": "+last);
    i++;
}

String []parts=line.split("\\s+");

System.out.println(parts[0]);
System.out.println(parts[1]);
System.out.println(parts[parts.length-1]);

Assuming the line has 3+ words, use the split(delimiter) method:

String line = ...;

String[] parts = line.split("\\s+"); // Assuming words are separated by whitespaces, use another if required

then you can access to the first, second and last respectively:

String first = parts[0];
String second = parts[1];
String last = parts[parts.length() - 1];

Remember that indexes starts with 0.

line.split("\\s+"); // don't use " ". use "\\s+" for more than one whitespace
