replace string with map value with if key is match with exact string

Map<String, String> hashtable = new Hashtable<>();
hashtable.put("eBook Cover Image", "724242");
hashtable.put("Cover Image", "95757");
hashtable.put("Image", "9242424");
hashtable.put("Composite", "7697979");
hashtable.put("Low-Res PDF (print)", "1111111111111111");
hashtable.put("Cover", "c11111111");

String s = "eBook Cover Image OR (Low-Res PDF (print) AND Composite)";

for (Map.Entry<String, String> m : hashtable.entrySet()) {
    s = s.replace(m.getKey(), m.getValue());
}

replacing is not happening properly.

eBook c11111111 9242424 OR (1111111111111111 AND pppppppppppppppp)

The order in which the entries are iterated is not set with Hashtable, so it looks like you're visiting "Image" before visiting "eBook Cover Image".

You probably want a LinkedHashMap where you put the longer keys in the map first (as you have in your example), because it will iterate the entries in insertion order (by default).
