Override HashMap put method

I have a HashMap declared as so:
HashMap <String, MyTableClass> tableMap = new LinkedHashMap<String, MyTableClass>();

I want to override the put method, so I created its own class:

public class TableHashMap extends LinkedHashMap {

      @Override
      public MyTableClass put (Object key, Object value) {
            MyTableClass table = (MyTableClass ) super.put(key, value);
            return table;
      }

}

As a class this compiles, but then the declaration statement doesn't compile, saying that it cannot be parameterized.
If I change both of the "Object" types to String and MyTableClass, then it has a compile error that says that the method put must override a supertype method.
How do I do this?

It is probably not a very good idea to extend HashMap and override put method ?
Why do you need it?

Too complex thing. Just find all puts and set breakpoints

You can do
public class TableHashMap<K, V> extends LinkedHashMap<K, V> {
        @Override
        public V put(K key, V value) {
            return super.put(key, value);
        }
    }
