java 对象的初始化过程

PersonDemo  p=new  PersonDemo("lisi",20);这句话都做了什么事情？

public class PersonDemo {
private String name="zhang";
private int age;
private static String country = "cn";

//静态代码块，对PersonDemo.class类进行初始化
static {
System.out.println("静态代码块" + country);
}

//构造代码块，对对象进行初始化
{
System.out.println("构造代码块" + this.name);
}

//构造方法
public PersonDemo(String name, int age) {
this.name = name;
this.age = age;
}

public void setName(String name) {
this.name = name;
}

public static void show() {
System.out.println("静态方法" + country);
}
}
