I am having trouble implementing the HuffmanEncode(), Here are the details of the method to be completed: import java.io.*; import java.util.*; public class HuffmanEncode { public HuffmanEncode(String in, String out) { //Implements the huffman encoding algorithm //Add private methods as needed } public static void main(String args[]) { new HuffmanEncode(args[0], args[1]); } }
