How to create a .zip file from two .doc file?

Question

I want to write a unit test to test creating .zip file from two .doc files. BU I take an error: Error creating zip file: java.io.FileNotFoundException: D:\file1.txt (The system cannot find the file specified)

My code is here:

@Test
public void testIsZipped() {

    String actualValue1 = "D:/file1.txt";
    String actualValue2 = "D:/file2.txt";

    String zipFile = "D:/file.zip";

    String[] srcFiles = { actualValue1, actualValue2 };

    try {

        // create byte buffer

        byte[] buffer = new byte[1024];

        FileOutputStream fos = new FileOutputStream(zipFile);
        zos = new ZipOutputStream(fos);

        for (int i = 0; i < srcFiles.length; i++) {

            File srcFile = new File(srcFiles[i]);

            FileInputStream fis = new FileInputStream(srcFile);

            // begin writing a new ZIP entry, positions the stream to the
            // start of the entry data

            zos.putNextEntry(new ZipEntry(srcFile.getName()));

            int length;

            while ((length = fis.read(buffer)) > 0) {

                zos.write(buffer, 0, length);
            }

            zos.closeEntry();

            // close the InputStream

            fis.close();
        }

        // close the ZipOutputStream

        zos.close();

    }

    catch (IOException ioe) {

        System.out.println("Error creating zip file: " + ioe);
    }

    String result = zos.toString();

    assertEquals("D:/file.zip", result);
}

Can I get name of zip file from zos to test, How to understand to pass the test? Can anybody help me to solve this error? Thank you.

My guess is that the file is either not there or the path is wrong (Windows uses `\` to separate path, which you have to escape. — hotzst, Oct 06 '15 at 14:24
Does `D:\file1.txt` exist? Do you have read rights to it? Possibly consider trying `D:\\file1.txt` — CollinD, Oct 06 '15 at 14:24
I created file1.txt and file2.txt files in D directory. Now there is no error but I did not pass the test. I tried these to define directory : "D:\\file1.txt", "D:\file1.txt" and "D:/file1.txt". — eponymous, Oct 06 '15 at 14:30

First, are your files created in a previous test method? If yes consider that junit tests do not execute in the order you defined your test methods, have a look at this:

Second, you could add a debugging line:

File srcFile = new File(srcFiles[i]);
System.out.append(srcFile+ ": " + srcFile.exists() + " " + srcFile.canRead());

After you solve the exception you will run into this problem, the test will fail:

String result = zos.toString();

assertEquals("D:/file.zip", result);

zos.toString() will return something like: "java.util.zip.ZipOutputStream@1ae369b7" which will not be equal to "D:/file.zip".

String zipFile = "D:/file.zip";
ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(zipFile));
System.out.println(zos.toString());
