Question

我有一个名为test.zip的压缩文件，该压缩文件中有2个文件file1.txt和file2.txt。我想使用核心Java概念更新file1.txt文件并添加一个文件file3.txt iin zip文件，而不提取zip文件。谁能建议我针对该用例使用哪种方法。预先谢谢你。

获取要执行的操作的文件，

     try (FileInputStream fis = new FileInputStream( String fileName = "C:/Users/Administrator/Desktop/log.zip";);
                    BufferedInputStream bis = new BufferedInputStream(fis);
                    ZipInputStream zis = new ZipInputStream(bis)) {

                ZipEntry ze;

                while ((ze = zis.getNextEntry()) != null) {

                    System.out.format("File: %s Size: %d Last Modified %s %n",
                            ze.getName(), ze.getSize(),
                            LocalDate.ofEpochDay(ze.getTime() / MILLS_IN_DAY));
                }
            }

然后获取如下的bufferreader对象，

    ZipEntry entry = entries.nextElement();
    InputStream stream = zipFile.getInputStream(entry);
    BufferedReader br = new BufferedReader(new InputStreamReader(stream, "UTF-8"));

拥有后，您可以将内容修改为

    while (line = br.readLine() != null)
        {
            if (line.contains("java"))
                line = line.replace("java", " ");
            lines.add(line);
        }
    FileWriter fw = new FileWriter(f1);
    BufferedWriter out = new BufferedWriter(fw);
    out.write(lines.toString());

更新Zip文件或zip文件中的文件，而无需使用Java提取zip文件
