Java 中空引用上的静态字段

java
public class Person {
    private String name;
    private int age;
    public static int totalCount;
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
        totalCount++;
    }
    // 省略其他代码
    public static void main(String[] args) {
        Person person1 = new Person("Alice", 25);
        Person person2 = new Person("Bob", 30);
        System.out.println("Total Person count: " + Person.totalCount);
    }
}
