解压缩文件夹时遇到问题 - 从文件夹到文件夹的文件

Question

下面是我将文件夹解压到目标文件夹的方法和方法定义

unzip(filepath, unzipLocation);

这是我解压缩 zip 文件的方法，此方法适用于文件，但是当我的 zip 文件像 a.zip 时出现问题，其中包含文件夹 2 文件夹（即 abc1，abc2），并且文件夹 abc1 有文件夹并且它有文件请帮帮我

private void unzip(String src, String dest) {

        try {
            fileInputStream = new FileInputStream(src);
            ZipInputStream zipInputStream = new ZipInputStream(new BufferedInputStream(fileInputStream));
            ZipEntry zipEntry;

            while ((zipEntry = zipInputStream.getNextEntry()) != null) {
                String zipEntryName = zipEntry.getName();
                String name = dest.substring(dest.lastIndexOf("/") - 1);
                //  System.out.println("NAME "+name);

public static void unZipIt(String zipFile, String outputFolder) {

    byte[] buffer = new byte[1024];
