Answer 1

Consider an operation which has to display the count as soon as the count gets incremented. ie., as soon as CounterThread increments the value DisplayThread needs to display the recently updated value.

int i = 0;

Output

CounterThread -> i = 1  
DisplayThread -> i = 1  
CounterThread -> i = 2  
CounterThread -> i = 3  
CounterThread -> i = 4  
DisplayThread -> i = 4

Here CounterThread gets the lock frequently and updates the value before DisplayThread displays it. Here exists a Race condition. Race Condition can be solved by using Synchronzation
