ArrayList 存储自定义对象并遍历，arraylist自定义

package exercise;

先创建Student类

package exercise;


public class Student {
private String name;
private int age;


public Student() {
super();


}


public Student(String name, int age) {
super();
this.name = name;
this.age = 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;
}
}

import java.util.ArrayList;
import java.util.Iterator;
/*ArrayList 存储自定义对象并遍历*/


public class ArrayListDemo {
public static void main(String[] args) {
// 创建集合对象
ArrayList array = new ArrayList<>();
// 创建学生对象
Student s1 = new Student("郭新兴", 25);
Student s2 = new Student("郭德纲", 55);
Student s3 = new Student("郭靖", 100);
// 添加元素
array.add(s1);
array.add(s2);
array.add(s3);
// 遍历
Iterator it = array.iterator();
while (it.hasNext()) {
Student s = (Student) it.next();
System.out.println(s.getName() + "----" + s.getAge());
}
System.out.println("--------");
for (int x = 0; x < array.size(); x++) {
Student s = (Student) array.get(x);
System.out.println(s.getName() + "----" + s.getAge());
}
}

}运行：
