How does ZipInputStream.getNextEntry() work?

Question

Say we have code like:

File file = new File("zip1.zip");
ZipInputStream zis = new ZipInputStream(new FileInputStream(file));

Let's assume you have a .zip file that contains the following:

• zip1.zip
  • hello.c
  • world.java
  • folder1
    • foo.c
    • bar.java
  • foobar.c

How would zis.getNextEntry() iterate through that?

Would it return hello.c, world.java, folder1, foobar.c and completely ignore the files in folder1?

Or would it return hello.c, world.java, folder1, foo.c, bar.java, and then foobar.c?

Would it even return folder1 since it's technically a folder and not a file?

Thanks!

Well... Lets see:

        ZipInputStream zis = new ZipInputStream(new FileInputStream("C:\\New Folder.zip"));
        try
        {
            ZipEntry temp = null;
            while ( (temp = zis.getNextEntry()) != null ) 
            {
             System.out.println( temp.getName());
            }
        }

Output:

New Folder/

New Folder/folder1/

New Folder/folder1/bar.java

New Folder/folder1/foo.c

New Folder/foobar.c

New Folder/hello.c

New Folder/world.java
