Appreciate your efforts. Usually if the word get repeated means duplicate. "Repeated 1 time" needs to be corrected.

I think the implementation of HashSet is more accurate for this question. HashSet never allows any duplicates. Here I will use an ArrayList to hold the repeated word. Here is my complete solution.

public class Abcd1 {
public static void main(String[] args) {
String str= "Gina Gini Protijayi Gini";

fix(str);
}

private static void fix(String str) {
List<String> list = new ArrayList<>();
Set<String> set = new HashSet<>();
String[] words = str.split("\\s+");

for( String word : words) {
if(set.contains(word))
}//for
System.out.println("list => " + list);
}
}
The output will be Gini which is the repeated word here.
