java编写解压7-ZIP、ACE、ALZ、ZIP、RAR、TAR、ZIP、RAR格式压缩包

Java语言可以使用Apache Commons Compress库来解压7-ZIP、ACE、ALZ、ZIP、RAR、TAR、ZIP、RAR格式压缩包。以下是一个示例代码：

import org.apache.commons.compress.archivers.ArchiveEntry;
import org.apache.commons.compress.archivers.ArchiveException;
import org.apache.commons.compress.archivers.ArchiveInputStream;
import org.apache.commons.compress.archivers.ArchiveStreamFactory;
import org.apache.commons.compress.archivers.zip.ZipArchiveEntry;
import org.apache.commons.compress.archivers.zip.ZipArchiveInputStream;
import org.apache.commons.compress.compressors.bzip2.BZip2CompressorInputStream;
import org.apache.commons.compress.compressors.gzip.GzipCompressorInputStream;
import org.apache.commons.compress.compressors.xz.XZCompressorInputStream;
import org.apache.commons.compress.compressors.z.ZCompressorInputStream;
import org.apache.commons.compress.utils.IOUtils;

import java.io.*;

public class Uncompressor {

    public static void main(String[] args) throws IOException, ArchiveException {
        File input = new File("compressed_file_path");
        File outputDir = new File("output_directory_path");

        try (InputStream inputStream = new FileInputStream(input);
             ArchiveInputStream archiveInputStream = new ArchiveStreamFactory()
                     .createArchiveInputStream(new BufferedInputStream(inputStream))) {

            ArchiveEntry entry;
            while ((entry = archiveInputStream.getNextEntry()) != null) {
                File outputFile = new File(outputDir, entry.getName());

                if (entry.isDirectory()) {
                    if (!outputFile.isDirectory() && !outputFile.mkdirs()) {
                        throw new IOException("Failed to create directory " + outputFile);
                    }
                } else {
                    try (OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(outputFile))) {
                        IOUtils.copy(archiveInputStream, outputStream);
                    }
                }
            }
        }
    }
}

该示例代码可以处理多种压缩包格式，如ZIP、RAR、TAR、GZIP、BZIP2、XZ和Z。你可以根据自己的需要选择要解压的压缩包格式。
