Understanding Java Threads:

• Creating threads using Thread class and Runnable interface;
• Starting threads;
• Multual exclusion using synchronized keyword;
• Putting on wait and resuming threads using wait() and notify()

Test 'Counter' programm from section Fire de executie. Replace start() method with run() method and observe the new behavior of the application.

Test 'TestSincronizare' programm from section Fire de executie. Uncomment synchronized blocks in FirGet and FirSet classes and test again the program. Compare the 2 different behaviors of the application - when using synchronized blocks and not using synchronized blocks.

Create 2 counters implemented using threads. First counter is incremented from 0 to 100. Second counter is incremented from 100 to 200 and start only after the first counter finish it's job.

Create a Robot class which simulate a robot which moves randomly in a 2D space (with a limited dimension of 100×100). Add in the 2D space 10 robots and start them. If at a particular point 2 robots arrives on the same location will collide and both of them are destroyed. The robots change their position at each 100 milliseconds.

Test consumer-producer application from section Fire de executie.

Create a chronometer in Java (including an UI). The chronometer will have 2 buttons. First button will start and pause the chronometer. Second button will reset the chronometer. The chronometer will be implemented as a java thread. wait/notify/synchrnozed must be used for implementing the chronometer behavior.
