D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:

Law of Demeter (LoD) is also called Least Knowledge Principle (LKP), which means that an object should know as little as possible about other objects.

This time, the execution of the next function system we constructed is affected, so we need to find an instruction with three consecutive pops to balance the stack. This kind of instruction is easy to find, as follows:
