در مورد Thread در جاوا

1. 1. java supports thread based multitasking.
   2. Multitasking using threads: once a program goes for execution it is the job of processor to execute the program. if the program contains some statements  that is eligible to transfer the data at that time process goes for "idle" state. to make our process com out from Idle state we are using multi threading concept.
   3. Multitasking has two types: 1-thread base  2-process based multitasking.
   4. what is process? the program under execution is known as process.
   5. what is thread? small part of program is known as thread.
   6. Java Doesn't support process based multitask. we can not execute  two programs at the same time.
   7. Java supports  only thread based multitasking.
   8. processor decides how many second it executes.
   9. to achieve thread based multitasking in Java we have to follow these steps:
   • We have to write all those statements inside 1 method which will execute as a thread.
   • There is a method in java API named "public void run" which can be used to identify the method as a thread and execute it as a thread.
   • in java API there  is the method "start" if we dont use start method to call run, then run method will be executed as a general method not the thread.
