Write a Java program to check a word contains the character 'g' in a given string.

Sample Solution:

Java Code:

import java.util.*;
import java.util.regex.Matcher;

public class test {
 
   public static void main(String[] args) {
	   
	    System.out.println(validate("The quick brown fox jumps over the lazy dog."));
	    System.out.println(validate("Java Exercises."));
	    System.out.println(validate("Do humans eat gizzards?"));
	    System.out.println(validate("gizzards?"));
        }

   public static String validate(String text) {
	    Pattern pattern = Pattern.compile("\\w*g.\\w*");
		 Matcher m = pattern.matcher(text);
		
	   if (m.find())
                return "Found a match!";
       else
