分析以下需求，并用代码实现

(1)定义一个学生类Student，包含属性：姓名(String name)、年龄(int age)

public class Student {

	String name;
	int age;
	
	
	public Student() {
		super();
		// TODO Auto-generated constructor stub
	}
	
	
	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;
	}
	
	
	@Override
	public String toString() {
		return "Student [name=" + name + ", age=" + age + "]";
	}
}

(2)定义Map集合，用Student对象作为key，用字符串(此表示表示学生的住址)作为value

	public static void main(String[] args){
		Map map = new HashMap<>();
		inputMap(map);		
		bianli01(map);
		bianli02(map);
	}

	public static void inputMap(Map map) {
		Student stu = new Student();
		stu.setName("wang");
		stu.setAge(23);
		map.put(stu, "beijing");
		Student stu1 = new Student();
		stu1.setName("zhao");
		stu1.setAge(22);		
		map.put(stu1, "shanxi");
		Student stu2 = new Student();
		stu2.setName("liu");
		stu2.setAge(19);		
		map.put(stu2, "fujian");
	}

(3)利用四种方式遍历Map集合中的内容，格式：key::value

	public static void bianli02(Map map) {
		Set> entrySet = map.entrySet();
		for(Entry entry : entrySet){
			System.out.println(entry.getKey()+"::"+entry.getValue());
		}
	}

	public static void bianli01(Map map) {
		Set set = map.keySet();
		for(Student student: set){
			System.out.println(student+"::"+map.get(student));
		}
	}
