If you are sure on that behaiour  of your class and sure that no one from outside world should not change the its behaviour, then you can make the class as final. Thats why java have String class as final why bcas java authors dont want to change its bahaviour.

With respect to multithreading, synchronization is the capability to control the access ofmultiple threads to shared resources. Without synchronization, it is possible for onethread to modify a shared object while another thread is in the process of using orupdating that object's value. This often leads to significant errors.

Synchronisation is a mechanism to make sure that exactly one thread will execute block with fresh values from main memory i.e. it must execute two way memory barrier. When thread enter into sync block then it must invalidate all values from cache and read from Main memory and vica versa

Shailesh Shinde

Synchronization makes sure that shared resources or data can be accessed by only one thread at a time while execution. its advantage is that it prevent data inconsistency and disadvantage is that it makes execution slower as it makes other thread wait till current thread completes execution.
