In the example, replace compressed with new File("PATH_TO_FILE"). The example code will yield an output stream, I suppose the LzmaOutputStream or the library has appropriate methods for converting the stream to binary or string.
By default Lzma is only a compression algorithm, not a file archiver like tar or zip. (Note: The 7-Zip program is a file archiver, but the library you linked to does not support file traversal and unpacking.
I would suggest using a well-supporter compression algorithm like Zip or gz. If you must use lzma you could use tar to build a file archive and then compress it with lzma. Or use zip with zero compression.

在示例中，将
compressed替换为 new File("PATH_TO_FILE")。示例代码将产生一个输出流，我想 LzmaOutputStream 或库具有将流转换为二进制或字符串的适当方法。默认情况下，Lzma 只是一种压缩算法，而不是像 tar 或 zip 那样的文件存档器。 （注意：7-Zip 程序是一个文件存档器，但您链接到的库不支持文件遍历和解包。
我建议使用支持良好的压缩算法，如 Zip 或 gz。如果您必须使用 lzma，您可以使用tar 构建文件存档，然后使用 lzma 对其进行压缩，或者使用零压缩的 zip
这是 java TAR 库。

Here is a java TAR library.
