What is the system effect of starting a large number of timers in Java?

Recently, I had to program some applications that require a large number of scheduled tasks. However, I am afraid to create so many timers because I could not understand how they are handled by Java. Is there a problem with starting a large number of scheduled tasks? If so, which alternative is better?
