我正在使用 java 创建一个 zip 文件，但我无法让任何代码工作。我尝试了更多特定于 java 7 和 java 8 的方法，但它们都显示出某种错误，我的代码是否有错误或需要改进？
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();
}
我在这一行得到一个错误zipFileAtLast.addFolder(inFolder, parameters);
请指导我:)
运行时的错误：
