Java(集合框架)用集合存储5个学生对象,用迭代器遍历

用集合存储5个学生对象,用迭代器遍历

主类:



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


public class IteratorTest {
     
	public static void main(String[] args) {
     
		//创建集合
		Collection c = new ArrayList();

		//创建学生对象
		Student s1 = new Student("任盈盈", 27);
		Student s2 = new Student("郭靖", 30);
		Student s3 = new Student("令狐冲", 33);
		Student s4 = new Student("黄蓉", 25);
		Student s5 = new Student("杨过", 22);

		//将学生对象添加到集合
		c.add(s1);
		c.add(s2);
		c.add(s3);
		c.add(s4);
		c.add(s5);
		//创建迭代器
		Iterator it = c.iterator();
		//遍历集合
		while(it.hasNext()){
     
			Student stu = (Student)it.next;
			System.out.println(stu.getName() + "==="+stu.getAge());
		}
			
	}
}

学生类:

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

	// 构造方法
	public Student() {
     
	}

	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;
	}

}
