need help with script :(

i started watching a unity tutorial and reached part 2

when he created a cube he added a script component and so did i,just when he typed Debug.log("hello");
his Debug changed color in visual studio and mine didnt i tryed saving it and running and i got error cs0117
code:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3. public class PlayerMovement : MonoBehaviour
4. {
5.     // Start is called before the first frame update
6.     void Start()
7.     {
8.         Debug.Log("hello");
9.     }
10.     // Update is called once per frame
11.     void Update()
12.     {
13.        
14.     }
15. }

picture in attached files

 

Script file name needs to be the exact same name as the class name!

lolz.cs should be PlayerMovement.cs

 

it didnt fix anything i did rename it still Debug didnt change

 

It is Debug.Log not Debug.log
Also you can try

Code (CSharp):

1. print("hello");
