如何解压Java中的Zip文件

要解压Java中的Zip文件，您可以使用Java内置的java.util.zip包

import java.io.*;
import java.util.zip.*;

public class UnzipFile {
    public static void main(String[] args) {
        // 指定要解压的Zip文件路径
        String zipFilePath = "path/to/your/zipfile.zip";
        
        // 指定解压后的文件存放目录
        String destDirectory = "path/to/your/destination/folder";
        
        try {
            unzip(zipFilePath, destDirectory);
            System.out.println("解压成功!");
        } catch (IOException e) {
            System.err.println("解压失败: " + e.getMessage());
        }
    }

    public static void unzip(String zipFilePath, String destDirectory) throws IOException {
        File destDir = new File(destDirectory);
        if (!destDir.exists()) {
            destDir.mkdir();
        }
        
        ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFilePath));
        ZipEntry entry = zipIn.getNextEntry();
        
        while (entry != null) {
            String filePath = destDirectory + File.separator + entry.getName();
            if (!entry.isDirectory()) {
                extractFile(zipIn, filePath);
            } else {
                File dir = new File(filePath);
                dir.mkdirs();
            }
            zipIn.closeEntry();
            entry = zipIn.getNextEntry();
        }
        zipIn.close();
    }

    private static void extractFile(ZipInputStream zipIn, String filePath) throws IOException {
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath));
        byte[] bytesIn = new byte[4096];
        int read = 0;
        while ((read = zipIn.read(bytesIn)) != -1) {
            bos.write(bytesIn, 0, read);
        }
        bos.close();
    }
}

请确保将zipFilePath和destDirectory变量替换为您要解压的Zip文件的路径以及要将解压后的文件存放的目标目录。然后编译并运行该程序，它将解压指定的Zip文件并将文件保存到目标目录。
