How to get Record Owner ID from record ID?

If u want to get the owner id/ user id of current record.

for this what I know, we have to do 2 things. 

1) First we have to fetch record ID from URL by using

   ApexPages.CurrentPage().getparameters().get('id');

2) We can fetch owner ID by using this record ID.

If I am correct then how to fetch record owner ID by using record ID? then leave a comment.

render - Boolean value (if it is true, it displays the block else it will be hidden)

reRender - ID. Particular block will be refreshed.

renderAs - Display the page as pdf, excel, etc...

 }

 public void setsearchCategory(String searchCategory)
 {
  this.searchCategory = searchCategory;
 }
