使用集合存储自定义类的类型数据

自定义类：One
public class One {
private int age;
private String name;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public One(int age, String name) {
super();
this.age = age;
this.name = name;
} }

使用集合存储
import java.util.ArrayList;

public class Demo05StudentJiHe {
public static void main(String[] args){
ArrayList a1=new ArrayList();
One sOne=new One(34,“sill”);
a1.add(sOne);
a1.add(new One(20,“zlx”));
for (One temp:a1){
System.out.println(temp.getAge()+"-"+temp.getName());
}
}
}
