Thread and Process are two closely related term in multi-threading and main
difference between Thread and Process in Java is that Threads are part of process. i.e. one process can spawn multiple
Threads. If you run
a Java program in UNIX based system e.g. Linux and if that program creates
10 Threads, it still one process and you can find that by using ps
-ef | grepidentifier command which is one of most popular
use of grep command in UNIX, Where identifier is unix
text which can be used as regular
expression to find that Java process. Another major difference between
Process and Thread is that, each process has its own separate memory space
but Threads from same process same memory space. Some linux command map Java
thread with light weight process or lwp, e.g. if
you use prstat command in Solaris, you can get
how many light weight process or Thread a particular Java program is using.
