Java method to determine whether two lists are equal

The following example can be regarded as a negative textbook, but it is actually wrong.

  public static boolean isEquals(List<String> list1,List<String> list2){
        if(null != list1 && null != list2){
            if((list2) && (list1)){
                return true;
            }
            return false;
        }
        return true;
    }
