What you said for 3 thread question is correct. But explanation is not. If we want t2 to start after t1, call t1.join(). But this wil be executed by main thread, not t2. When we have t1.join(), code after this line will not be executed. Main thread waits for completion of t1 and then only main thread executes lines which are afte t1.join().

finalize is not used for garbage collection. Whatever the code write within finalize method gets executed, just before JVM executes garbage collection process. So, finalize is the last method which gets executed before garbage collection.
