You can use JOIN() method to execute them one after another.
e.g :- t1.start();
t1.join();
t2.start();
t2.join();

There is no way to determine which thread is executed first, it is solely dependent on the scheduling algorithms adapted by the operating system and underlying hardware architecture, one way to guarantee the that the thread runs in a particular order is using synchronized methods.

We have to implement run method to create a thread.We need to make that method synchronized so that only one thread can go inside and control will be given to second only and only of first is completed.

We can do that by using the join. In the second thread run method, we can call the join on first thread object. In the third thread run method, we can call the join on second thread object. Like this way, we can make sure first thread will execute before second and secondll execute before third thread.
