13.3 Multithreading using Runnable Interface

In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.
Multithreading in java is a process of executing multiple activities can proceed concurrently in the same program.
Thread is basically a lightweight sub-process, a smallest unit of processing.
In multithreading threads share a common memory area.
They don't allocate separate memory area so saves memory, and context-switching between the threads takes less time than process.

Multiple threads can exist within the same process and share resources such as memory, while different processes do not share these resources.
Using two different task at the same time means multi-tasking. Thread is unit of a process.

[sreenivask]

Great job sir u r videos are very helpful

[gladyouseen]

Why we are using the reference of runnable? Can we use interfaces to refer objects? Why? Please tell me 3:42

[rajshreegavel]

I have a query, we cannot make object of an interface then why is it written -> 'Runnable' obj1 = new Hi(); or 'Runnable' obj2 = new Hello();

[vibhorsteele]

@Telusko Hi! How did you go to the declaration of the interface runnable at 0:47? Which shortcut did you use? Kindly tell me how to see the documentation using that keyboard shortcut?

[ValatY]

Wow that's really well explained! Thanks man

[shyamkachhadiya]

Ah sir can we have some more videos on Runnable and multithreading please :)

[simplelife]

Sir, why cant we simply write

obj1.run();


instead of,


Thread t1 = new Thread(obj1);
t1.show();

[nakulvs]

i have a doubt.What is the difference between "different threads with different instance of the class and different threads with the same instance of the class" ?

[raghavenderraosaini]

what is the difference between an abstract class and an interface if have two methods in getting a thread
