In Go language, the method call is done using the “.” symbol. To call a method, simply add the “.” symbol after the object or type, followed by the method name. Example:

package main
import "fmt"
type Person struct {
    name string
    age int
}
func (p Person) SayHello() {
    fmt.Printf("Hello, my name is %s. I am %d years old.\n", p.name, p.age)
}
func main() {
    p := Person{name: "Alice", age: 20}
    p.SayHello() // 调用Person类型的SayHello方法
}

In the example above, we defined a Person struct and a SayHello method. In the main function, we created a Person object p and called the SayHello method using p.SayHello().
