OPEN_READ

public static final int OPEN_READ

OPEN_DELETE

public static final int OPEN_DELETE

Mode flag to open a zip file and mark it for deletion. The file will be deleted some time between the moment that it is opened and the moment that it is closed, but its contents will remain accessible via the ZipFile object until either the close method is invoked or the virtual machine exits.

Constructor Detail

ZipFile

Opens a zip file for reading. First, if there is a security manager, its checkRead method is called with the name argument as its argument to ensure the read is allowed. The UTF-8 charset is used to decode the entry names and comments.

ZipFile

public ZipFile​(File file, int mode) throws IOException

Opens a new ZipFile to read from the specified File object in the specified mode. The mode argument must be either OPEN_READ or OPEN_READ | OPEN_DELETE . First, if there is a security manager, its checkRead method is called with the name argument as its argument to ensure the read is allowed. The UTF-8 charset is used to decode the entry names and comments

ZipFile

public ZipFile​(File file) throws ZipException, IOException

Opens a ZIP file for reading given the specified File object. The UTF-8 charset is used to decode the entry names and comments.

ZipFile

public ZipFile​(File file, int mode, Charset charset) throws IOException

Opens a new ZipFile to read from the specified File object in the specified mode. The mode argument must be either OPEN_READ or OPEN_READ | OPEN_DELETE . First, if there is a security manager, its checkRead method is called with the name argument as its argument to ensure the read is allowed.

ZipFile

public ZipFile​(String name, Charset charset) throws IOException

Opens a zip file for reading. First, if there is a security manager, its checkRead method is called with the name argument as its argument to ensure the read is allowed.

ZipFile

public ZipFile​(File file, Charset charset) throws IOException

Method Detail

getComment

getEntry

getInputStream

public InputStream getInputStream​(ZipEntry entry) throws IOException

Returns an input stream for reading the contents of the specified zip file entry. Closing this ZIP file will, in turn, close all input streams that have been returned by invocations of this method.

getName

entries

stream

Returns an ordered Stream over the ZIP file entries. Entries appear in the Stream in the order they appear in the central directory of the ZIP file.

size

close

Closes the ZIP file. Closing this ZIP file will close all of the input streams previously returned by invocations of the getInputStream method.

finalize

@Deprecated(since="9", forRemoval=true) protected void finalize() throws IOException

The finalize method has been deprecated and will be removed. It is implemented as a no-op. Subclasses that override finalize in order to perform cleanup should be modified to use alternative cleanup mechanisms and to remove the overriding finalize method. The recommended cleanup for ZipFile object is to explicitly invoke close method when it is no longer in use, or use try-with-resources. If the close is not invoked explicitly the resources held by this object will be released when the instance becomes unreachable.

Ensures that the system resources held by this ZipFile object are released when there are no more references to it.

getNextEntry

closeEntry

available

Returns 0 after EOF has reached for the current entry data, otherwise always return 1. Programs should not count on this method to return the actual number of bytes that could be read without blocking.

read

Reads from the current ZIP entry into an array of bytes. If len is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0 is returned.
