如何將Collection應用到實際開發當中

//舉個例子

//Student類

public class Student {

public String name;

public String age;

public Student(String name, String age) {

	this.name = name;
	
	this.age = age;

}

public String getName() {

	return name;
}

public void setName(String name) {

	this.name = name;
}
public String getAge() {

	return age;
}

public void setAge(String age) {

	this.age = age;
}

[@Override](https://my.oschina.net/u/1162528)

public String toString() {

	return "Student [name=" + name + ", age=" + age + "]";
	
}
}

// bianli_student

public class bianli_student { public static void main(String args[]) {

Collection c= new ArrayList();
	  
	  Student s1=new Student("mao","11");
	  
	  Student s2=new Student("mao","12");
	  
	  Student s3=new Student("mao","13");
	  
	  c.add(s1);
	  
	  c.add(s2);
	  
	  c.add(s3);
	  
	  
	  Object b[]=c.toArray();
	  
	  for(int i=0;i<b.length;i++) {
	  
		  Student s=(Student) b[i];
		  
		  System.out.println(s.getName()+" "+s.getAge());
	  }
}

}
