import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;

public class StringChecker {

public static void main(String[] args) {
ArrayList string;
string = new ArrayList<>(Arrays.asList("Mah", "Bob", "mah", "bat", "MAh", "BOb"));
Map wordMap = new HashMap();

for (String st : string) {
    String input = st.toUpperCase();
    if (wordMap.get(input) != null) {
        Integer count = wordMap.get(input) + 1;
        wordMap.put(input, count);
    } else {
        wordMap.put(input, 1);
    }
}
System.out.println(wordMap);
Object maxEntry = Collections.max(wordMap.entrySet(), Map.Entry.comparingByValue()).getKey();
System.out.println("maxEntry = " + maxEntry);
