Answer 1

You are repeating the whole word here .. a possible fix is

public static void repeatLetters()
{
   String text = "dean";
   int n = 3;
   StringBuilder repeat = new  StringBuilder();

   for (int i = 0; i < text.length() ; i++)
   {
        for (int j= 0; j< n; j++)
            repeat.append(text.charAt(i));
   }

  System.out.println(repeat);
}
