考虑将单个文件test_file.pdf放入zip存档test.zip然后读取此存档的代码示例:

import java.io.*;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
import java.util.zip.ZipOutputStream;

public class Main {
    public static void main(String[] args) {
        File infile = new File("test_file.pdf");
        try (
                FileInputStream fis = new FileInputStream(infile);
                ZipOutputStream zos = new ZipOutputStream(new FileOutputStream("test.zip"));
        ) {
            int bytesRead;
            byte[] buffer = new byte[1024];
            ZipEntry entry = new ZipEntry("data");
            entry.setSize(infile.length());

            zos.putNextEntry(entry);
            while ((bytesRead = fis.read(buffer)) >= 0)
            {
                zos.write(buffer, 0, bytesRead);
            }
            zos.closeEntry();

        } catch (IOException e) {
            e.printStackTrace();
        }

        try (
