无法使用zip4j在Java中创建zip文件

Question

我正在使用Java创建一个zip文件，但无法获取任何代码。 我尝试了更多特定于Java 7和Java 8的方法，但是它们都显示出某种错误，我的代码是否存在错误或需要改进？

            File destination = null;
            JFileChooser chooser1 = new JFileChooser();
            chooser1.setDialogTitle("Select a directory with APK file contents");
            chooser1.setCurrentDirectory(new java.io.File("."));
            chooser1.setAcceptAllFileFilterUsed(false);
            chooser1.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            int returnVal = chooser1.showOpenDialog(getParent());
            if (returnVal == JFileChooser.APPROVE_OPTION) {
                destination = chooser1.getSelectedFile();
                JFileChooser chooser2 = new JFileChooser();
                FileNameExtensionFilter filter = new FileNameExtensionFilter("APK Files", "apk");
                chooser2.setFileFilter(filter);
                chooser2.setDialogTitle("Save APK as");
                int userSelection = chooser2.showSaveDialog(parentFrame);
                if (userSelection == JFileChooser.APPROVE_OPTION) {
                    File apksavedestination = chooser2.getSelectedFile();
                    String apkname = chooser2.getSelectedFile().getName() + ".apk";
                    String zipFile = apksavedestination + apkname;
                    String zipfileSource = destination.getAbsolutePath();

                    try {
                        ZipFile zipFileAtLast = new ZipFile(zipFile);
                        ArrayList<File> inFolder = new ArrayList<File>();
                        inFolder.add(new File(destination.getAbsolutePath()));
                        ZipParameters parameters = new ZipParameters();
                        parameters.setIncludeRootFolder(false);
                        parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);
                        parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_NORMAL);
                        zipFileAtLast.addFolder(inFolder, parameters);
                    } catch (ZipException e1) {
                        e1.printStackTrace();
                    }

我在这行收到一个错误zipFileAtLast.addFolder(inFolder, parameters);

请指导我:)

运行时错误：

我知道了。 问题是，所有解决方案都需要首先将File对象转换为字符串！
