Answer / venod.r.g
Thread is a class which extends Thread class or Implements
Runnable Interface.
Thread can run as an Independant process than current
Excecution steps. The Main thread that runs always is known
as CurrentThread accessed by Thread.currentThread();
Only one thread can access CPU time ( JVM then CPU). Multi
thread mechanisum is possible by making several threads in
waiting state and running only one at a time.
JVM assign priorities for every threads and accesses in a
Time Slicing / scheduled way considering the OS.
Defauls is normal.
Every object is like a Football to threads. hence Every
object must have methods to handle a thread. All the
players may be running in the field but only one player can
handle the Ball at a time. Object have methods like wait(),
notify() notifyAll() etc to catch and release the working
thread.
If you do not want a ball to change shape once it is
accessed by a thread then you need to synchronise the
statements or methods. Once synchronized the thread which
is the owner of the Object can only change the state of the
object.
//Method
public void synchronized x(){
}
//statement
synchronized (x);

Answer / sharvari
Thread is a unit of program code in execution. It is unit of
dispatching.
Thread can be viewed as an independent program counter
within a process.
Basically it reduces switching overhead and helps
multiprogramming.

Answer / bhushan
Thread is light weight process.
One Process can have multiple threads.
Eg:
I opened Microsoft Word doc and writing at the same time
spell checker is also running.
It implies in 1 process multiple threads can run
simultaneously with less overhead.
To create separate process for different functionality will
create overhead.
