不能从静态上下文引用非静态方法toString

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

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

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

    public static void main(String[] args) {
        // 错误示例：不能从静态上下文引用非静态方法toString
        // System.out.println(Person.toString());

        // 正确示例：创建类的实例，然后调用非静态方法
        Person person = new Person("Alice", 30);
        System.out.println(person.toString());
    }
}
