遍历学生（HashSet+foreach）

package study;

import java.util.HashSet;

//利用hashset创建且遍历对象（foreach）
public class fuction {
public static void main(String[] args) {
HashSet hs=new HashSet();
Student s=new Student(“lena”,18);
Student s2=new Student(“danie”, 18);
hs.add(s);
hs.add(s2);
for(Student student:hs){
System.out.println(student.name+student.age);
}
}
}
class Student{

int age;

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