When computer code is considered atomic it can not be interrupted during its execution, We can also define atomic code as code that can’t be found in an intermediate state. Atomicity in Java - Java specifies that basic loading and storing of variable is the atomic. That means the value of the variable can’t be found in a interim state during the store not be changed in the middle of loading the variable to a register.

In that case, when one thread changes the values of the variable, another thread may not see the changed value. This is particularly in loops where looping is controlled by a variable.
