python java 解压缩

Python和Java都有一些解压缩库可以用来解压缩文件。对于Python，您可以使用zipfile模块，它提供了用于解压缩zip文件的功能。下面是一个示例代码，演示了如何使用zipfile模块解压缩zip文件：

import zipfile

zip_file = "path/to/your/zip/file.zip"
extract_dir = "path/to/extract/folder"

with zipfile.ZipFile(zip_file, 'r') as zip_ref:
    zip_ref.extractall(extract_dir)

对于Java，您可以使用java.util.zip包中的ZipInputStream类来解压缩zip文件。下面是一个示例代码，演示了如何使用ZipInputStream解压缩zip文件：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class UnzipExample {
    public static void main(String[] args) {
        String zipFile = "path/to/your/zip/file.zip";
        String extractDir = "path/to/extract/folder";

        try {
            byte[] buffer = new byte[1024];
            File folder = new File(extractDir);
            if (!folder.exists()) {
                folder.mkdir();
            }

            ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream(zipFile));
            ZipEntry zipEntry = zipInputStream.getNextEntry();
            while (zipEntry != null) {
                String fileName = zipEntry.getName();
                File newFile = new File(extractDir + File.separator + fileName);
                new File(newFile.getParent()).mkdirs();

                FileOutputStream fileOutputStream = new FileOutputStream(newFile);
                int length;
                while ((length = zipInputStream.read(buffer)) > 0) {
                    fileOutputStream.write(buffer, 0, length);
                }
                
                fileOutputStream.close();
                zipEntry = zipInputStream.getNextEntry();
            }
            
            zipInputStream.closeEntry();
            zipInputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
