JList Manipulation - How Operating Systems Manage Processes

I am attempting to use JLists to complete a program that models how operating systems manage processes. A quick synopsis of what it is supposed to do. Each process is to have a priority level (I chose to do 1 -3 with 3 being the most important) and there are supposed to be three lists. One for ready processes, blocked processes, and a running process.

My issues:

1) when I block a process it does indeed switch lists but when it is copied into the blocked list it pulls the element number instead of what the actual process number is. For ex: Say the ready list has 5 processes / I delete 2 / Leaving process 1, 2, 5. When I block 5, it gets registered in the blocked list as process 2.

2) I can't figure out how to give a label to each of my scroll panels (JLists) to signify which box is ready / blocked / and running

3) My switch button - I have commented in what I need to do but don't know how I am going to do it.

Below are my files:

Main

import java.util.Comparator;
import java.util.PriorityQueue;
import java.util.Queue;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class PQueue {
public static void main(String[] args) throws InterruptedException {
