Errors in Unity2D

I keep getting 2 errors. It is a very basic code that i have written before and it worked well for me. But I can't find whats wrong with it. the errors are "Assets/Scripts/player.cs(12,14): error CS0116: A namespace can only contain types and namespace declarations" and "Assets/Scripts/player.cs(21,1): error CS8025: Parsing error"

 using UnityEngine;
 using System.Collections;
 
 public class player : MonoBehaviour {
 
     // Use this for initialization
     public Vector2 jumpForce = new Vector2 (0, 300);
     
     }
     
     // Update is called once per frame
     void Update () 
     {
         // Jump
         if (Input.GetKeyUp("space"))
         {
         rigidbody2D.velocity = Vector2.zero;
         rigidbody2D.AddForce(jumpForce);
         }
     }
 }
