Thread.currentThread always returns the current thread
1. In the printMsg method, assign the current thread to the variable t.
2. In the printMsg method, add a delay of 1 millisecond after all the actions.

Consecutive threads
1. In the run method, add a delay of 10 milliseconds after all the actions. Display "Thread interrupted" if the thread is interrupted.
2. Make all the threads run sequentially: first, for thread 1, count down from COUNT to 1; then for thread 2 - from COUNT to 1, etc.
Example:
#1: 4
#1: 3
...
#1: 1

Creating threads recursively
1. Change the GenerateThread class to make it a thread.
2. Create a GenerateThread constructor, which must:
2.1. Call the superclass's constructor, passing the created thread's number as a String. Use createdThreadCount.
2.2. Start the current thread.
2.3. The thread numbers must start with 1.

Consecutive threads
1. Figure out what the program does.
2. Make the program first display the result of the thread, and when the thread has finished then the main method continues.
3. Example output:
inside MyThread 0
inside MyThread 1
...
inside MyThread 9
inside main 0
inside main 1
...
inside main 9

1. Figure out how the program works.
2. Without changing the T1 and T2 classes, make it so their threads finish (not necessarily successfully).

Read about UncaughtExceptionHandler - it's important.
Take another careful look at the program.
Figure out why our OurUncaughtExceptionHandler doesn't work (use the debugger).
Fix the bug, i.e. everything should work. :)
