How to search inside an String array for Names using created database

Total noob here.

I just started learning java and would like to create a program so my teacher does not need to count everyone just to figure out who is missing.

For this, I would need input data. We use teams to learn java so the people who are attending could write something in chat so the teacher can copy/paste this as input data for my program.

This is what I already have:

    String names = "Tupac Shakur,Randy Bobandy,Michael Scott,Randy Marsh,Leslie Knope,you mum gey,no u";

    String[] arr = names.split(",");
    System.out.println("Bot NaniPoonani: Who is here Tool v1 ");
    System.out.println("Bot NaniPoonani: Copy/paste the chat data here: ");
    Scanner inputNames = new Scanner(System.in);
    String ScanNames = inputNamen.next();


    String[] FilterdInputNames = ScanNamen.split(Arrays.toString(arr));

    String[] FilterdNames = names.split(",");

    for (String ss : arr);
    System.out.println(" ");
    System.out.println(" ");
    System.out.println(" ");
    System.out.println(" ");

    System.out.println(Arrays.toString(FilterdInputNames));
}

This code did not work how I expected and I'm kinda blocked. The second problem is the chat input is filled with not need data, here is an example:

> [Yesterday 4:44 PM] Tupac Shakur
    
Ja Patrick..
​[Yesterday 4:45 PM] James Bond
    cya
​[Yesterday 4:45 PM] Nikola Tesla

My first thought was that I could use .split to fill an array with each name using the not needed data

[Yesterday 4:44 PM] Tupac Shakur (enter or /n )

something like this: String[] FilterdInputNames = ScanNamen.split("M]" + "/n"); But clearly, that's not how slipt works.

All advice is welcome since I am not even sure if I need to filter the not needed data.

Thank you in advance
