Why Volatile? How Compiler come to know about external event changeed d variable or through progr..

Answer / gourav kumar

volatile is actually a keyword which is used in java. when
it is used before a variable then it tells the value of the
variable which is being modified by different threads.

the value of the variable will not be cached thread locally
all the read and write operation is done from direct to the
main memory.
