 Process memory space = Heap Each application has its own memory space, also known as the heap.  The heap isn't shared between two applications or two processes, they each have their own. A thread is a single unit of execution, within a process. Each process can have multiple threads. Every application has at least one thread, and that is the main thread.  Threads are fundamental building blocks, to support concurrency, in a java application. They are essential, because they allow us to perform multiple tasks simultaneously, within a single process.  package org.example ; public class Main { public static void main (String[] args) { Thread currentThread = Thread. currentThread () ; System. out .println(currentThread.getClass().getName()) ; System. out .println(currentThread) ; printThreadState (currentThread) ; currentThread.setName( "MainGuy" ) ; currentThread.setPriority(Thread. MAX_PRIORITY ) ; printThrea...
