What is Volatile Keyword in Java ?

The volatile keyword guarantees global ordering on reads and writes to a variable. This implies that every thread accessing a volatile field will read the variable’s current value instead of using a cached value.

By marking the variable volatile, the value of a variable is never cached thread-locally. All reads and writes will go straight to main memory of Java.
