Bellow code work fine

import java.util.Scanner;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class DuplicateRemoveEx {

public static void main(String[] args){

    String regex="(?i)\\b(\\w+)(\\b\\W+\\1\\b)+";
    Pattern p = Pattern.compile(regex,Pattern.CASE_INSENSITIVE);

    Scanner in = new Scanner(System.in);
    int numSentences = Integer.parseInt(in.nextLine());
    while(numSentences-- >0){
        String input = in.nextLine();
        Matcher m = p.matcher(input);
        while(m.find()){
            input=input.replaceAll(regex, "$1");
        }
        System.out.println(input);
    }
    in.close();
}

}
