先创建学生类
package cn.itcast_04;
public class Student {
private String name;
private int age;
public Student() {
super();
}
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;
}
}
再创建集合类
package cn.itcast_04;
import java.util.ArrayList;
import java.util.Collection;
import java.util.Iterator;
/*
* 需求：存储自定义对象并遍历Student(name,age)
*
* 分析：
* A:创建学生类
* B:创建集合对象
* C:创建学生对象
* D:把学生对象添加到集合对象中
* E:遍历集合
*/
public class CollectionTest2 {
public static void main(String[] args) {
// 创建集合对象
Collection c = new ArrayList();
// 创建学生对象
Student s1 = new Student("貂蝉", 25);
Student s2 = new Student("小乔", 16);
Student s3 = new Student("黄月英", 20);
Student s4 = new Student();
s4.setName("大乔");
s4.setAge(26);
// 把学生对象添加到集合对象中
c.add(s1);
c.add(s2);
c.add(s3);
c.add(s4);
c.add(new Student("孙尚香", 18)); // 匿名对象
// 遍历集合
Iterator it = c.iterator();
while (it.hasNext()) {
Student s = (Student) it.next();
System.out.println(s.getName() + "---" + s.getAge());
}
}
}
还是比较基础，希望对您有帮助！
