string reg = "([A-z][a-z],\s+([A-z][a-z]+)";

using pattern pattern = pattern.compile(reg);

add the regular expression to the working javafx code & show output. (could you use ? if so pls)

import java.util.regex.*;

import java.util.*;

import java.io.*;

public class JavaRegex {

public static void main(String args[]){

/*

//Search words in text.

String text = "ThJAVAis is a jaVARegular javaExpressiJaVAon";

String word = "JAVA";

System.out.println(text);

Pattern pattern = Pattern.compile(word,Pattern.CASE_INSENSITIVE);

Matcher matcher = pattern.matcher(text);

while (matcher.find()){

System.out.printf("word= %s start at %d , end at %d ",matcher.group(),matcher.start(),matcher.end());

}

*/

/*

System.out.println(s);

//Open file and extract more words

//String reg = "([A-z][a-z]+),\s+([A-z][a-z]+)";

/*

Matcher matcher = pattern.matcher(text);

while (matcher.find()){

System.out.print(matcher.group(1));

System.out.print(matcher.group(2));

System.out.println(matcher.group(3));

}

}

}

catch(FileNotFoundException e) {

}

*/

}

}

i just want you to explain the program and add the regular expression with warning & pattern!
