Threads in Java

Question

I’m having trouble understanding threads in Java, can someone explain what is it and when is it used?

Answer 1

first you learn what is draw back of thread....why we we use thread...

in previous we use sequential flow of execution...but problem is...if task 1 start second task2 is stop..but this stop time..we not. use another task...

that is we use thread...

multiple task run at a time parallel way
..is called as thread.
run method is reserve method..
if we call start all run method run parallel..way.

I hope you understand.

Answer 2

To understand thread Let me give an example..

In earlier days and in some OS now also when we open a web page data gets loaded and it comes in a proper sequence...
like first text..then gif..then video...

and thus it is the work of thread to present everything in a sequential maner and one task precedes the other.

Answer 3

Threads are useful for multitasking purpose..
Here is an example:
Assume that you are playing a game at the same time you want to listen music.. that means multitasking at a same period of time..
Threads are useful to run multiple tasks concurrently like as to play music and video game and alot more.
