package parsestrings;

import java.util.Scanner;

public class ParseStrings {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in); // Input stream for standard input

Scanner inSS = null; // Input string stream

String lineString = ""; // Holds line of text

String firstWord = ""; // First name

String secondWord = ""; // Last name

boolean inputDone = false; // Flag to indicate next iteration

// Prompt user for input

System.out.println("Enter input string: ");

// Grab data as long as "Exit" is not entered

while (!inputDone) {

// Entire line into lineString

lineString = scnr.nextLine()

// Create new input string stream

inSS = new Scanner(lineString);

// Now process the line

firstWord = inSS.next();

// Output parsed values

if (firstWord.equals("q")) {

System.out.println("Exiting.");

inputDone = true;

if (firstWord.matches("[a-zA-Z]+,[a-zA-Z]+")) {

System.out.print("Input not two comma separated words");

}

} else {

secondWord = inSS.next();

System.out.println("First word: " + firstWord);

System.out.println("Second word: " + secondWord);

System.out.println();

}
