In Go language, calling a structure method requires first defining the structure and the method that binds the receiver, and accessing it using a point number. After defining the structure Rectangle, the method can be declared through the value receiver or the pointer receiver; 1. Use the value receiver such as func(rRectangle)Area()int and directly call it through rect.Area(); 2. If you need to modify the structure, use the pointer receiver such as func(r*Rectangle)SetWidth(...), and Go will automatically handle the conversion of pointers and values; 3. When embedding the structure, the method of embedded structure will be improved, and it can be called directly through the outer structure; 4. Go does not need to force use getter/setter,

In Go, an interface is a type that defines behavior without specifying implementation. An interface consists of method signatures, and any type that implements these methods automatically satisfy the interface. For example, if you define a Speaker interface that contains the Speak() method, all types that implement the method can be considered Speaker. Interfaces are suitable for writing common functions, abstract implementation details, and using mock objects in testing. Defining an interface uses the interface keyword and lists method signatures, without explicitly declaring the type to implement the interface. Common use cases include logs, formatting, abstractions of different databases or services, and notification systems. For example, both Dog and Robot types can implement Speak methods and pass them to the same Anno

Go's time package provides functions for processing time and duration, including obtaining the current time, formatting date, calculating time difference, processing time zone, scheduling and sleeping operations. To get the current time, use time.Now() to get the Time structure, and you can extract specific time information through Year(), Month(), Day() and other methods; use Format("2006-01-0215:04:05") to format the time string; when calculating the time difference, use Sub() or Since() to obtain the Duration object, and then convert it into the corresponding unit through Seconds(), Minutes(), and Hours();

The standard way to protect critical areas in Go is to use the Lock() and Unlock() methods of sync.Mutex. 1. Declare a mutex and use it with the data to be protected; 2. Call Lock() before entering the critical area to ensure that only one goroutine can access the shared resources; 3. Use deferUnlock() to ensure that the lock is always released to avoid deadlocks; 4. Try to shorten operations in the critical area to improve performance; 5. For scenarios where more reads and less writes, sync.RWMutex should be used, read operations through RLock()/RUnlock(), and write operations through Lock()/Unlock() to improve concurrency efficiency.
