Java / Java Multithreading
Explain race condition in multithreading.
Race conditions occurs when 2 or more threads operate on same object without proper synchronization and the steps on the operation interleaves on other thread.
An example of Race condition is incrementing a counter since increment is not an atomic operation and can be further divided into three steps like read, update and write. If two threads tries to increment count at same time and if they read same value because of interleaving of read operation of one thread to update operation of another thread, one count will be lost when one thread overwrite increment done by other thread. atomic operations are not subject to race conditions because those operation cannot be interleaved.
