for (JsonElement jsonElement : jsonArray) {
    String name = jsonElement.getAsJsonObject().get("name").getAsString();
    int age = jsonElement.getAsJsonObject().get("age").getAsInt();
    System.out.println("Name: " + name + ", Age: " + age);
}

public class Person {
    private String name;
    private int age;

    // 省略getter和setter方法
}

Gson gson = new Gson();
Person[] persons = gson.fromJson(jsonString, Person[].class);

for (Person person : persons) {
    System.out.println("Name: " + person.getName() + ", Age: " + person.getAge());
}
