Java – Atomic increment of long variables?

If the long variable is declared as: –

Long counter = 0;

Now, if I use the pre increment operator to increment it, is the operation atomic?

If so, it will be better than Java util. concurrent. atomic. Is the increment of atomiclong objects more efficient?

Solution

The volatile keyword can only solve the visibility problem You must use atomiclong or atomicity in concurrent programming of synchronized methods / blocks
