Previously we used the lock shortcut to enable multi-threaded sharing of the same resource. In C #, lock is actually a simplified version of the monitor operation.Use monitor below to complete the previous lock function, you can do a comparison here:

Definition of stacks1, stack is a special kind of linear table2, the stack can only operate at one end of the linear table3, Top: Agree on one end of the operation4, bottom of Stack (Bottom):, do not agree with one end of the operationHere I made

Let's start by analyzing the differences between Java and C + +:Java is a purely object-oriented language, and C + + is a language based on object-oriented procedures.Java has a garbage collection mechanism. Its syntax is a subset of C + +, which
