yes u can but be sure to use it under try-catch block.
Actually synchronized keyword is basically used for locking
purpose. let us consider an example:-

/*This is a synchronized block*/
Synchronized(this){
try{Thread.sleep(1000);}catch(InterruptedException e){}
//Remaining code
}
Now suppose there is s thread in a program say A
let us consider thread A enters the synchronized block
because of sleep method it'll take one second more than its
normal execution time.that's it. it will affect other
threads that are waiting for that particular resource.
without thread.sleep method
