从Java到Go面向对象--类的定义和实例化对象

面向对象基本思想

Java中类的定义

class Person {

String name;

public Person(String name) {
this.name = name;
}

void sayHi() {
System.out.println(this.name + "Hello World.");
}

}

Java实例化对象

Person person = new Person("liyang");
person.sayHi();

Go中类的定义

type Person struct {
name string
}

func (person *Person) sayHi() {
fmt.Println(person.name + " Hello World.")
}

var person1 = Person{name: "liyang"}
person1.sayHi()
