Jackson: how to deserialize a JSON array of objects in Java

Hello everyone. I just started learning Java and Jackson, and I have a problem. I have a JSON string that is an array of objects. For example, here is such JSON:\n\n

[\n  {"name": "Alice", "age": 30},\n  {"name": "Bob", "age": 25},\n  {"name": "Charlie", "age": 35}\n]

\n\nI'm trying to read this JSON and turn it into a list of objects of my `Person` class. My class looks like this:\n\n

public class Person {\n    private String name;\n    private int age;\n\n    // Default constructor\n    public Person() {}\n\n    // Getters and setters\n    public String getName() { return name; }\n    public void setName(String name) { this.name = name; }\n    public int getAge() { return age; }\n    public void setAge(int age) { this.age = age; }\n}
