Uncompress BZIP2 archive
提问by cletus
I can uncompress zip, gzip, and rar files, but I also need to uncompress bzip2 files as well as unarchive them (.tar). I haven't come across a good library to use.
我可以解压缩 zip、gzip 和 rar 文件，但我还需要解压缩 bzip2 文件以及解压缩它们 (.tar)。我还没有遇到一个好的库来使用。
I am using Java along with Maven so ideally, I'd like to include it as a dependency in the POM.
理想情况下，我将 Java 与 Maven 一起使用，我想将它作为依赖项包含在 POM 中。
What libraries do you recommend?

The best option I can see is Apache Commons Compresswith this Maven dependency.
我能看到的最佳选择是具有此 Maven 依赖项的Apache Commons Compress。
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-compress</artifactId>
<version>1.0</version>
</dependency>
From the examples:
从示例中：
FileInputStream in = new FileInputStream("archive.tar.bz2"); FileOutputStream out = new FileOutputStream("archive.tar"); BZip2CompressorInputStream bzIn = new BZip2CompressorInputStream(in); final byte[] buffer = new byte[buffersize]; int n = 0; while (-1 != (n = bzIn.read(buffer))) { out.write(buffer, 0, n); } out.close(); bzIn.close();
FileInputStream in = new FileInputStream("archive.tar.bz2"); FileOutputStream out = new FileOutputStream("archive.tar"); BZip2CompressorInputStream bzIn = new BZip2CompressorInputStream(in); final byte[] buffer = new byte[buffersize]; int n = 0; while (-1 != (n = bzIn.read(buffer))) { out.write(buffer, 0, n); } out.close(); bzIn.close();
