for loop
• for ( int i = 0; i < length; i++ ){                           s.paintAt( x+i , y, paintChar );    }
•Variable i is declared inside for statement
•Surround body with braces {...}for safety
•i++ is short for i = i+1 (or i += 1)
•Can do the same job other ways:
•for (int col=x+len-1; col >=x; col-- ){                           s.paintAt( col , y, paintChar );  
•}
