Can smb explain this question?

Hi! How does the answer happen to be 12?? Thanks in advance!

Java Code:

public static void main(String [] args)
        {
                int i = 5;  
                for(i=0;i<=10;i++)
                {  
                   i=i+1;  
                }  
                System.out.println(i);
 
                
        }
