Considering the below code for an exercise problem, where is the specification that says roughly: "Upon the call to readTokens(), wait for the user to press carriage return and then continue execution."

I'm not fully understanding why my code works, why does the program pause after "Enter Data: " is displayed and wait for a carriage return? Where is this behavior defined and how can it be changed?

```
import java.io.*;
import java.util.LinkedList;

public class StreamTokeTwo {

private int ttype = 0;
StreamTokenizer tokenizer = new StreamTokenizer(new BufferedReader(
        new InputStreamReader(System.in)));

private void setupTokenizer() {
    tokenizer.resetSyntax();
    tokenizer.wordChars(33, 126);
    tokenizer.whitespaceChars(0, 32);
    tokenizer.whitespaceChars(44,44);
    tokenizer.whitespaceChars(47,47);
    tokenizer.eolIsSignificant(true);
}

private String[] readTokens() {
    LinkedList<String> list = new LinkedList<String>();
    String[] array = null;

    do {
        try {
            ttype = tokenizer.nextToken();
        } catch (Exception e) {
            System.exit(1);
        }
        if (ttype == StreamTokenizer.TT_WORD) {
            list.add(tokenizer.sval);
        }
    } while (ttype != StreamTokenizer.TT_EOL);

    array = list.toArray(new String[0]);
    return array;
}

public static void main(String[] args) {
    StreamTokeTwo streamToke = new StreamTokeTwo();
    streamToke.setupTokenizer();

    for (int i = 0; i < 5; ++i) {
        System.out.print("Enter data: ");
        String[] array = streamToke.readTokens();
        for (String str : array) {
            System.out.print(str + " ");
        }
        System.out.println();
    }
}
}

```
