1.分析：
1.定义学生类
2.创建集合对象
3.创建学生对象
4.把学生对象作为元素添加到集合中
5.遍历集合并输出
2.代码实现
第一步，定义学生类：
package day02;
public class StudentTest2 {
private String name;
private int age;
private String home;
public StudentTest2() {
}
public StudentTest2(String name, int age, String home) {
this.name = name;
this.age = age;
this.home = home;
}
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;
}
public String getHome() {
return home;
}
public void setHome(String home) {
this.home = home;
}
}
第二步，定义测试类：
package day02;
import java.util.ArrayList;
//创建学生类
public class ArrayListTest2 {
public static void main(String[] args) {
//创建集合对象
ArrayList<StudentTest2> array = new ArrayList<StudentTest2>();
//创建学生对象
StudentTest2 s1 = new StudentTest2("樊浩岚",19,"中国");
StudentTest2 s2 = new StudentTest2("李倩倩",17,"乌克兰");
StudentTest2 s3 = new StudentTest2("王寅森",18,"南部非洲");
StudentTest2 s4 = new StudentTest2("王长卫",20,"印度");
//添加元素到集合
array.add(s1);
array.add(s2);
array.add(s3);
array.add(s4);
//遍历集合
for(int x=0;x<array.size();x++){
StudentTest2 stu = array.get(x);
System.out.println(stu.getName()+"-----"+stu.getAge()+"----"+stu.getHome());
}
}
}
