Initialization of a stringbuffer

Question

I would like to know if it is possible in the code below to initialize "feedback" to a number of '_' equal to the length of "code". Is there anything in a string api that would allow me to do this?
public class stringTest
     StringBuffer feedback; // replace this example variable with your own
String code="alicja";;
     * Default constructor for objects of class stringTest
     public stringTest()
     {super();
     feedback=new StringBuffer(code);
     }

as this is kind of quiz. So?
I code a password and replace it with "*". Each time you guess a letter star changes into a letter. problem is that if I do a method it would reset my stringbuffer every turn to a number of *s. This is why I wanted to initiazlize it in a constructor and than write a method to replace stars with letters
StringBuffer sb = new StringBuffer(myMethod('*', count));StringBuffer has a c'tor that takes a String, so all you have to do is write a tiny little method that takes in a character and a count and builds up a String from them.
Or, you could create an empty SB, then pass it to a method that calls append as many times as you need. What's the difference if you initialize the SB or fill it up one statement later?
