我的zip提取器不断收到java.io.FileNotFoundException

Question

Could anybody help me with my java zip extractor as stated in the title I keep getting java.io.FileNotFoundException on the folders with files in them

public void UnZip() {
    try {
        byte[] data = new byte[1000];
        int byteRead;

        BufferedOutputStream bout = null;
        ZipInputStream zin = new ZipInputStream(new BufferedInputStream(new FileInputStream(sourceFile)));
        ZipEntry entry;
        while ((entry = zin.getNextEntry()) != null) {
            String filename = entry.getName();
            File newfile = new File(Deobf2 + File.separator + filename);

            System.out.println("file unzip : " + newfile.getAbsoluteFile());

            new File(newfile.getParent()).mkdirs();

            FileOutputStream fos = new FileOutputStream(newfile);

            int len;
            while ((len = zin.read(data)) > 0) {
                fos.write(data, 0, len);
            }

            fos.close();
            entry = zin.getNextEntry();
        }
        zin.closeEntry();
        zin.close();

        System.out.println("Done");
    } catch (Exception e) {
        e.printStackTrace();
    }
}

values

static String tempDir = System.getProperty("java.io.tmpdir");
public static File Deobf = new File(tempDir + "Deobf");
public static String Deobf2 = Deobf.toString();

entire code paste http://pastebin.com/1vTfABR1

Answer 1

I have copy pasted same code and it is working fine. I think u dont have administrator permission on C drive. login As Administrator and run . it will work. Access Denied Exception will come when u don have administrator level of permission on C drive.

Answer 2

The problem is Your doing

String Deobf2 = Deobf.toString();//this does not give the location of the file

use

file.getAbsolutePath();

in your case Deobf.getAbsolutePath();

instead. Check http://www.mkyong.com/java/how-to-get-the-filepath-of-a-file-in-java/ if you want to get the path only till the parent directory check this How to get absolute path of directory of a file?

已解决问题的地方更改了一些代码，以供任何想要在此处获取工作zip提取代码副本的人使用，请访问http://pastebin.com/bXL8pUSg zip输出中的变量Deobf2
