A variable may return unexpected results when multiple threads run in parallel. Here, we need athread-safecode to prevent deadlocks in Java. Example: Consider a bank where only one token counter is available for token distribution. The task here is to create aBankclass only when a customer ...
We have defined a static initialization block in class A and it is executed as soon as we run our program. Static initialization block can only access static variable of a class Similar to the principle of static method, a static initialization block can only access static variables and static...
