Taking Information From Google Doc And Storing To Be Able To Print Later

I've looking for information on taking a range of data from a google sheet such as the one below.

JavaGroupCat.png

The function that i'm trying to accomplish is allowing a user to run the program and input their 5-digit Unique - ID. After inputting their 5-Digit ID the program will take that input, and check whether or not that ID is present on the spreadsheet.

Ex: (Using the numbers from above) I type in : "89504" then (I would want the program to spit out if the ID is on the sheet).
(89504 appears on the sheet) So i would want it to print out something like "ID is found on list "Cat".
Associated named include: "Phil Roberts".

I tried, with my limited knowledge, to create what I have described above.

import java.io.*;
import java.util.*;
public class SwitchesTwo
{
public static void main(String args[]) {
System.out.println("Welcome to the ID # Checker");
System.out.println("Enter the ID of the person you are trying to verify");

[Code].....

The issue I have with the mock-up above is the fact that I have to manually add in every individual name and ID. I would much rather write code that would allow it to update as I update the spreadsheet. Therefore, no need for 800+ cases. (theres around 800 ID numbers for this project)

In a perfect world, the code would be something like "Take info from cells C5 - C2000 and store as string array" (I think array would work.) while also doing the same with B5 - B2000.
