HashMap Search for part of an key? [duplicate]

Answer 1

For example:

public static void checkMap(Map mp) {
    Iterator it = mp.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pairs = (Map.Entry)it.next();
        System.out.println(pairs.getKey().toLowerCase().contains("YourString"))
        }
}

This code will print true for those keys which contain your substring.
