如何打印具有特定属性的ArrayList中的一个或多个对象？

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        // 创建一个ArrayList存储学生对象
        ArrayList<Student> students = new ArrayList<>();

        // 添加一些学生对象到ArrayList中
        students.add(new Student("Alice", 20));
        students.add(new Student("Bob", 17));
        students.add(new Student("Charlie", 19));
        students.add(new Student("David", 22));

        // 遍历ArrayList中的每个学生对象
        for (Student student : students) {
            // 判断学生对象的年龄是否大于等于18岁
            if (student.getAge() >= 18) {
                // 打印满足条件的学生对象
                System.out.println(student);
            }
        }
    }
}

class Student {
    private String name;
    private int age;

    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}
