集合框架(Collection存储学生对象并遍历)

核心代码块：

package cn.ithelei;

public class Student {
// 成员变量
private String name;
private int age;

// 构造方法
public Student() {
    super();
}

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


// 成员方法
// getXxx()/setXxx()
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;
}

@Override
public String toString() {
    return "Student [name=" + name + ", age=" + age + "]";
    }
}

//

 package cn.ithelei;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Iterator;
