class Person{
	String name; //成员变量
	void talk(String name){
		//String name 形参
		System.out.println("My name is " + this.name);
	}
}

public class TestThis{
	public static void main(String[] args){
		Person p1 = new Person();
		p1.name = "zhangsan";

	}
}

class Person{
	String name;
	void talk(String name){

}

class Person{
	String name;
	int age;
	String address;
	
	Person(){
		System.out.println("test0");
	}
	Person(String name,int age){
		this();
		this.name = name;
		this.age = age;
		System.out.println("test2");
	}
	Person(String name,int age,String address){
		this(name,age);
		System.out.println("test3");
	}
	
	
}

public class TestThis{
	public static void main(String[] args){
