javaee的toString的用法

toString方法返回该对象的字符串表示,如果不用toString则返回的是地址
package Xuexi;

public class Person {
   private String name;
   private int age;
public String getName() {
	return name;
}

public void setName(String name) {
	this.name = name;
}
public int getAge() {
	return age;
}

public void setAge(int age) {
	this.age = age;
}

    public String toString(){
    	String str=this.name+"..."+this.age;
		return str;
    }

}
package Xuexi;

public class Test01 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
       Person p1=new Person();
       String str=p1.toString();
       System.out.println(str);
	}

}
