Multitasking in Java allows for the simultaneous execution of multiple tasks through two types: process-based and thread-based multitasking. Process-based multitasking involves heavyweight processes with high communication costs and separate memory allocation, while thread-based multitasking uses lightweight threads that share memory, reducing costs and allowing independence among threads. The document also includes a sample code demonstrating thread creation in Java.

Multithreading and Multitasking in JAVA

2. Overview
A process of executing multiple tasks simultaneously is known as Multitasking.

3. Program
package quipoin;
class Demo extends Thread {
public void run() {
System.out.println("Thread is running!!");
}
public static void main(String args[]) {
Demo t1 = new Demo(); t1.start();
}
}

4. Types
It is of two types:-
Process-Based Multitasking:-
•The process is a heavyweight.
•The high communication costs involved in the process.
•Each process allocates a separate memory area i.e. each process has an address in memory.
Thread-Based Multitasking:-
•Thread is a small unit of processing that operates as a lightweight sub-process..
•The cost of communication between the Thread is low.
•It uses a shared memory area, they don't allocate separate memory areas so Threads saves
memory.
•Thread is independent. If any exception occurs in one Thread it doesn't affect another thread.
