This repository contains Java code for Huffman encoding and decoding, along with supporting classes for working with Huffman codes. Huffman coding is a widely used algorithm for data compression that assigns variable-length codes to input characters based on their frequencies.

Jun 27, 2024 · The Huffman coding is a popular algorithm used for lossless data compression. It works by assigning the variable-length codes to the input characters with the shorter codes assigned to the more frequent characters. This results in the prefix-free code meaning no code is a prefix of any other code.

The Huffman Coding project is a Java-based implementation of the Huffman encoding algorithm for file compression and decompression. It processes text files to build Huffman trees based on character frequency, encodes them into compact binary formats, and decodes them back into the …

This project implements Huffman Coding — a data compression technique — in Java. It was developed as part of the Data Structures and Operating Systems module in 2021. The application performs both encoding (compression) and decoding (decompression) of strings using a custom-built Huffman tree, simulating real-world compression techniques.

May 10, 2024 · We use the Huffman Coding algorithm for this purpose which is a greedy algorithm that assigns variable length binary codes for each input character in the text file. The length of the binary code depends on the frequency of the character in the file.

In this section, we will discuss the Huffman encoding and decoding, and also implement its algorithm in a Java program. We know that each character is a sequence of 0's and 1's and stores using 8-bits. The mechanism is called fixed-length encoding because each character uses the same number of fixed-bit storage.

Oct 12, 2023 · The Huffman coding is a data compression algorithm that creates a binary tree of nodes. The node can be either internal nodes or leaf nodes. This tutorial describes and demonstrates the Huffman code with Java in detail.

Apr 22, 2025 · Huffman coding is a lossless data compression algorithm. The idea is to assign variable-length codes to input characters, lengths of the assigned codes are based on the frequencies of corresponding characters.

Nov 27, 2022 · * ******************************************************************************//** * The {@code Huffman} class provides static methods for compressing * and expanding a binary …

Huffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree.
