I am not aware how to customise as per the image.
You can use

i need a unique id to identify the text field(start - press)(end - press) mention in the below image
there is no id, name or class to identify them
this is the xml code seen in inspect element.
Try using
//input[contains(#placeholder,'Start')]
or
//div[#class="leaflet-routing-geocode"]/input
i think
By.cssSelector("input[placeholder=\"Start - press enter to drop
marker\"]")
...ought to work

Currently, I can get back a list of users from an Active Directory group but I would like to return more than just their CN/name. How would I do this?
For example, I have an AD group with 20 members. I can get their names but I would also like to return their job title in the output as well.
In fact, you can get their DNs from the group. To get any other attribute, you need to do an additional query (getAttributes) for each member.

The question is not too dificult: How do I best implement a table in Java.
I wish to have something like a table in a database. Named columns and numbered rows. My values are Integer.
My inital idea: LinkedHashMap<String, ArrayList<Integer>>
But is there a better way of doing it?
What do you mean by "better"? It depends on what do you need to do with that.
You may build
a 2-dimensional array and a map of column names (C++ way)
a list of objects, where each object is a row (the most Java way)
a Guava Table
