Why can using synchronized(this) in a static method become a real problem?
Multiple choiceMediumchapter-15-curatedpremiumconcurrencysynchronized-and-locks
Answer and explanation
Correct answer
B. It has no effect since static methods cannot use this.
Why
Static methods do not belong to any instance of a class, and therefore cannot use 'this'. Attempting to use 'synchronized(this)' in a static method results in a compile-time error.
