ArrayList存储自定义对象并遍历，要求加入泛型，并用增强for遍历，arraylistfor

import java.util.ArrayList;
import java.util.Iterator;
public class ArrayListDemo1 {


public static void main(String[] args) {
//创建集合对象
ArrayList<Student> array = new ArrayList<Student>();

//创建学生对象
Student s1 = new Student("林青霞", 27);
Student s2 = new Student("吴居兰",18);
Student s3 = new Student("王守义",46);

//把学生对象添加到集合中
array.add(s1);
array.add(s2);
array.add(s3);

//创建迭代器
Iterator<Student> it =array.iterator();
while(it.hasNext()) {
Student s = it.next();
System.out.println(s.getName()+"----"+s.getAge());
}


System.out.println("---------");

//普通for
for(int x=0;x<array.size();x++) {
Student s = array.get(x);
System.out.println(s.getName()+"----"+s.getAge());
}
System.out.println("---------");

//增强for
for(Student s : array) {
System.out.println(s.getName()+"----"+s.getAge());
}
}
