...ANSWER
Answered 2021-Apr-19 at 05:39It is better to use the match
query if you have a text
type field.
term query doesn't perform any analysis on the term. It returns the documents that contain exact term matching documents.
terms query works on exact terms. It returns those documents that have 1 or more exact terms.

QUESTION
I created an abstract class Fruit, which overrides the equals() method. Then I created a subclass, Orange, which overrides the copy() and the equals() method. In my test file, TestFruit.java, I am creating an array of oranges and testing their methods. I am trying to create a deep copy of orange and do a deep comparison between the parent orange and the copy. However, in my output, the comparison always returns false. I checked the parent and the copy's attributes and they do seem to be the same. Any pointers would be appreciated. I am pretty new to Java and copying. I attached my code below.

...ANSWER
Answered 2021-Mar-05 at 05:47One of the common misconceptions in Java is the use of ==
vs .equals()
. When you use ==
to compare two objects in Java, internally it's comparing its memory address. ==
does not actually call .equals()
.
In this case, you have two distinct orange objects, so the comparison will always return false.
If you use a.equals(b)
, then it will actually invoke your equals
method which you implemented.
As @Andreas pointed out in the comments, there's another issue. Calling super.equals(obj)
in Fruit
will call the superclass implementation of equals
, and the superclass of Fruit
is Object
. Object.equals()
behaves the same as ==
(i.e. also checking for reference equality). Overriding .equals()
is not trivial, so it can often be nice to have the IDE generate it for you.
In contrast with a language like C++, Java does not have operator overloading. This means that you can't define a different implementation for ==
. This is why it's best practice to always call .equals()
when comparing any non-primitive types (unless you're explicitly checking reference equality, which is rare).

...ANSWER
Answered 2020-Apr-20 at 21:58It's just because of position: relative
.
EXPLAINATION
added position: relative
CSS to the .dropdown-item
class because your ::after CSS not works without position: relative
.
Removed position: relative
CSS from the .dropdown-submenu
class because Its calculate top
from its height
