What happens to child thread when you delete main thread during run-time?

In Java, if the main thread somehow exits then all other threads will stop executing. This generally does not happen, as the main thread will wait for all child threads to terminate before the main thread itself finishes. Interrupting this process is hard to do short of an un-handled exception or a call to System.exit.
If the child thread is also a daemon thread, then the child thread will continue to execute. If the child thread is a normal thread then, the moment System.exit is called, the child thread also terminates
If you call the join() method from the child thread, then the main thread will wait until the child is over before executing the System.exit

What is the name of the method used to schedule a thread for execution?
"start" You've created a Thread object and it knows its target. Now it's time to get the whole thread thing running. It's pretty straight forward: t.start(); Prior to calling start() on a Thread instance, the thread (when we use lowercase t, we're referring to the thread of execution rather than the Thread class) is said to be in the new state as we said. The new state means you have a Thread object but you don't yet have a true thread. So what happens after you call start()? • A new thread of execution starts (with a new call stack). • The thread moves from the new state to the runnable state. • When the thread gets a chance to execute, its target run() method will run.

Sometimes we like to leave threads around for someone to look at later. If you have a good reason to want your thread deleted, contact a supervisor. It would open room for abuse. If someone didn't like how their thread was going, they could delete it. If you would like it implemented, post in the suggestion box section in the Community Forum
