如何更新java对象数组中的变量

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

    // 构造方法和getter/setter方法省略

    public void updateAge(int newAge) {
        this.age = newAge;
    }
}

public class Main {
    public static void main(String[] args) {
        Person[] people = new Person[3];
        people[0] = new Person("Alice", 25);
        people[1] = new Person("Bob", 30);
        people[2] = new Person("Charlie", 35);

        // 更新对象数组中的变量
        for (Person person : people) {
            if (person.getName().equals("Bob")) {
                person.updateAge(32);
            }
        }

        // 打印更新后的对象数组
        for (Person person : people) {
            System.out.println(person.getName() + " - " + person.getAge());
        }
    }
}
