There is a newer version available. For the latest stable version, please use Compress4J 5.x!

LZMA

Here is a simple example of how to use LZMA compression. It requires org.tukaani:xz at runtime, the same library the XZ formats use; see Additional Formats.

Example Usage

LZMA Compression

try (LZMACompressor lzmaCompressor =
        LZMACompressor.builder(Path.of("example.lzma")).build()) {
    lzmaCompressor.write(Path.of("path/to/file.txt"));
}

LZMA Decompression

try (LZMADecompressor lzmaDecompressor = LZMADecompressor.builder(Path.of("example.lzma"))
        .compressorInputStreamBuilder()
        .setMemoryLimitInKb(65536)
        .parentBuilder()
        .build()) {
    lzmaDecompressor.write(Path.of("path/to/file.txt"));
}
