Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static void`	`compress()` Reads a sequence of 8-bit bytes from standard input; compresses them using Huffman codes with an 8-bit alphabet; and writes the results to standard output.
`static void`	`expand()` Reads a sequence of bits that represents a Huffman-compressed message from standard input; expands them; and writes the results to standard output.
`static void`	`main(String[] args)` Sample client that calls `compress()` if the command-line argument is "-" an `expand()` if it is "+".

  - main
```
public static void main(String[] args)
```
    Sample client that calls compress() if the command-line argument is "-" an expand() if it is "+".
