Java中把對象放入ArrayList集合中實現方法

package com.xuexi;

import java.util.ArrayList;
class Person{
//	成員變量
	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;
	}
//	toString方法重寫
	@Override
	public String toString() {
		return "name=" + name + ", age=" + age + "";
	}
}

public class TestArrayList {
	public static void main(String[] args) {
		ArrayList<Person> list=new ArrayList<Person>();
		Person p1=new Person();
		p1.setName("Tom");
		p1.setAge(3);
		Person p2=new Person();
		p2.setName("Jack");
		p2.setAge(4);
		Person p3=new Person();
		p3.setName("LiNing");
		p3.setAge(5);
		list.add(p1);
		list.add(p2);
		list.add(p3);
//		遍歷
		for(Person p1Info:list){
			System.out.println(p1Info);
	 }
	}
}
