```go
|
|||
|
|
type Car struct {
|
|||
|
|
color string
|
|||
|
|
size string
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
方式一：使用T{…}方式，结果为值类型
|
|||
|
|
```go
|
|||
|
|
c := Car{}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
方式二：使用new的方式，结果为指针类型
|
|||
|
|
```go
|
|||
|
|
c1 := new(Car)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
方式三：使用&方式，结果为指针类型
|
|||
|
|
```go
|
|||
|
|
c2 := &Car{}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
以下为创建并初始化
|
|||
|
|
```go
|
|||
|
|
c3 := &Car{"红色", "1.2L"}
|
|||
|
|
c4 := &Car{color: "红色"}
|
|||
|
|
c5 := Car{color: "红色"}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
构造函数：
|
|||
|
|
在Go语言中没有构造函数的概念，对象的创建通常交由一个全局的创建函数来完成，以
|
|||
|
|
NewXXX 来命名，表示“构造函数”
|
|||
|
|
```go
|
|||
|
|
func NewCar(color,size string) *Car {
|
|||
|
|
return &Car{color,size}
|
|||
|
|
}
|
|||
|
|
```
