如何在Jolt中获取arraylist中具有某些属性的对象

import java.util.ArrayList;

public class JoltArrayListExample {
    public static void main(String[] args) {
        // 创建一个ArrayList对象，并添加元素
        ArrayList<Person> personList = new ArrayList<>();
        personList.add(new Person("John", 25));
        personList.add(new Person("Jane", 30));
        personList.add(new Person("Bob", 40));
        
        // 定义过滤条件：年龄大于等于30
        int filterAge = 30;
        
        // 创建一个ArrayList对象，用于存储满足条件的Person对象
        ArrayList<Person> filteredList = new ArrayList<>();
        
        // 遍历ArrayList，筛选满足条件的Person对象
        for (Person person : personList) {
            if (person.getAge() >= filterAge) {
                filteredList.add(person);
            }
        }
        
        // 输出满足条件的Person对象
        for (Person person : filteredList) {
            System.out.println(person.getName() + " - " + person.getAge());
        }
    }
}

class Person {
    private String name;
    private int age;
    
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
    
    public String getName() {
        return name;
    }
    
    public int getAge() {
        return age;
    }
}
