If you are talking about last two statements (with t2 & t3) then they are creating two threads to run simultaneously. Thread constructor is passed a runnable object (t1 - MyThread) which is what the thread will be executing on.
2.passing object and thread name as parameters wht happens when i m passing a runnable object as parameter.
No problem. Thread has few constructors you can use. If you passed in a name you may identify the thread later easily by name.
3.why is this statement written in MYthread constructor
That thread doesn't do anything here. It's that two threads namely t1 & t2 do the actual job.
