    Default Writing data to binary file.

    I am a begginer in programming with Java. I have to write a simple program which can compress a .txt file (for example dictionary).
    - loading dictionary to memory (done)
    - building Huffman's tree (done)
    - writing it to .bin file (here is a problem)

    When I try to write my String (for example "011011") to .bin I have much bigger file than .txt, I have to convert it to binary type and save bit after bit but I have no idea how to do that. What should I do first? I have string and I have to save it to a .bin file. Maybe could anyone write a function which may do that?

    prototype of function:
    public void saveToBin(String txt)

    No one will write the method for you, but we can direct you to the correct place.
    I'm not 100% sure, but I would say that you need to use a Byte Stream. Here is a brief tutorial that you should find helpful: Byte Streams (The Java™ Tutorials > Essential Classes > Basic I/O)

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.
