Sybil | in-memory database | Database library

The goal is to collect grades from 5 different students by calling their name and then getting a grade average while using the first for-loop, and then collecting student scores by using another for-loop.

I'm trying to do pagination on the angular. I found a working solution in Google, but I can’t correctly implement it.

app.component.ts

I am researching how to use reflection to initialize a custom object. As an example, my object has several fields of differing types, however NONE of the fields are of the String type. I used chararrays instead of strings because I want to clear the objects out and not worry about immutable Strings being around in the heap should the applictation crash.

In addition, because the class implements CharSequence, the static fields buff, offset, and count are required. Also worth mentioning, the getters and setters are synchronized since this object will be used in a multi-threaded environment. Finally, there is a custom list of Person objects called People which lives in its own People.java file and is a customized collection of Person objects. Additional details about the object are elided for brevity.

The question is, how do I test for empty, blank, or null fields in my Person object? In my main class, I want to test for null, empty, or blank before inserting said object into a backend database. I have tried creating both a Person.isNull() and a similar Person.hasNull() function to test for empty values in the char[] fields, but the results are ABSOLUTELY NOT what I expected. The println statemnt inside the test for isCharArray revealed some THINGS I CURRENTLY DO NOT UNDERSTAND.....

Here is some sample output:
