problem on create a new class

when i create a class to separate the objects and then when i call on the Main class, it doesnt recognize and keep getting ''cannot resolve symbol'', the code only works if i put everything on the main class

main class

package com.company;
import java.time.LocalDate;
public class Main {



    public static void main(String[] args) {


        User person1 = new User();
        person1.name = "Fulano";
        person1.birthdateUser = LocalDate.of(1970, 5, 17);
        person1.age = LocalDate.now().getYear() - person1.birthdateUser.getYear();

        System.out.println(pessoa1.getNome() + " tem " +  pessoa1.getIdade() + " anos");



    }



}

users class

import java.time.LocalDate;

public class Users {

    public static class User {

        private String name;
        private LocalDate birthdateUser;
        private int age;


        public User(){

        }


        public Usuario(String name, LocalDate birthdateUser, int age) {
            this.name = name;
            this.birthdateUser = birthdateUser;
            this.age = LocalDate.now().getYear() - birthdateUser.getYear();

        }

        public String getName() {

            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public LocalDate birthdateUser() {
            return birthdateUser;
        }

        public void setbirthdateUser(LocalDate birthdateUser) {
            this.birthdateUser = birthdateUser;
        }
        public int getage() {

            return age;
        }

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

    }

}
