Description

it would be good to have hints showing some warning message("mutable method xyz cannot be used on immutable collection") when immutable collections are used with mutable methods.

example:

var immutableList = List.of(10,20);
      immutableList.add(20);

var immutableList = List.of(10,20);
      immutableList.remove(20);

• below are the methods which ImmutableCollections.AbstractImmutableList has below operations which throws UnsupportedOperationException

        @Override public boolean add(E e) { throw uoe(); }
        @Override public boolean addAll(Collection<? extends E> c) { throw uoe(); }
        @Override public void    clear() { throw uoe(); }
        @Override public boolean remove(Object o) { throw uoe(); }
        @Override public boolean removeAll(Collection<?> c) { throw uoe(); }
        @Override public boolean removeIf(Predicate<? super E> filter) { throw uoe(); }
        @Override public boolean retainAll(Collection<?> c) { throw uoe(); }
  

• at the moment no hint is shown
