Question

For reference, I am creating a Huffman tree for an assignment in school. I have created the tree, and stored values in a map using this format:

map.put((char,string));

char: is derived by reading one character at a time from a buffered reader
string: is the “binary” code assigned to that character based on its tree placement

Now I want to produce a String of “binary” that represents my initial input from the buffered reader. How do I do this? This is what I’ve tried:

String binary = "";
int q;    
while ((q = buffer.read()) != -1) {
  char key = (char)q;
  char value = (char)key.get();
  binary += value;
}
System.out.println(binary);

Answer 1

shouldn’t it just be value = map.get(key) ?
