consumed by the neighboring process.These four conditions are necessary for the deadlock, as long as the system has a deadlock, these conditions must be established, and as long as one of the above conditions is not satisfied, there will be no deadlock. Release and prevention of deadlocks:1. Ignore the problem. For example, the ostrich algorithm, the algorithm can be applied in the case of very few deadlocks occur.Why is called the

Cyclic wait condition (Circular wait): Several processes in the system make up loops in which each process waits for resources that are being consumed by neighboring processes.13. Policies to handle deadlocks: Ignore the problem. For example, the ostrich algorithm, the algorithm can be applied in the case of very few deadlocks occur. Why is called the ostrich algo

teacher instance field and the ToString method.Subclasses extend the parent class, which is a special parent class, and usually the subclass is always based on the parent class, adding new field and methods. But there is aExceptions, such as birds have a way of flying, where ostriches are birds, but it flies in a different way than other birds, so we need to rewrite the bird'sFlight methods to meet the ostrich's flight patterns, the code is as follows:Define a bird's classpublic class Bird {pub

Structure Diagram following the liskov replacement principle. Note: The Kingfisher class extends the bird base class and inherits the fly () method. However, the following class structure diagram has design problems: Class structure diagram that violates the liskov replacement principle. Ostrich (Ostrich) is a type of bird, which is beyond doubt inherited from the bird class, which is conceptually correct

A combination of so-called classes refers to the fact that member data in a class is an object that has a class or a pointer or reference to a class.The combination of classes enables more complex abstractions based on existing abstractions. Like what:1, by value combination#include 2, by reference combinationClass zooanimal{public://private:endangered *_endangered1;//By pointer combination endangered _endangered2;//by reference combination};See another example: Suppose the bird is capable of fl

Three characteristicsPackagingEncapsulate objective things into abstract classes, and classes can put their own data and methods only trusted classes or objects operation, to the untrusted information hiding.InheritedInheritance refers to the ability to use all the functionality of an existing class and to extend these capabilities without rewriting the original class. The process of its inheritance is from the general to the special process.CombinationIf a bird can fly, then is the

Object-C ---) Swift (9) Delayed Storage attributes Swift introduces a new mechanism-delay storage attribute mechanism, which is used to calculate the attribute of the initial value when it is called for the first time. lazy modifier is required for declaration.Note: When defining an attribute, it must be a variable (var). constants cannot use the delay storage mechanism. When is latency storage used? When an instance holds a reference for another instance with a high creation cost, usi
