ZipFile JDK 1.6)

Constructors

public ZipFile (File file) throws ZipException IOException

Opens a ZIP file for reading given the specified File object.

public ZipFile (File file, int mode) throws IOException

Opens a new ZipFile to read from the specified File object in the specified mode.

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.
Parameters:
- file - the ZIP file to be opened for reading
- mode - the mode in which the file is to be opened
Throws:
- ZipException - if a ZIP format error has occurred
- IOException - if an I/O error has occurred
- SecurityException - if a security manager exists and its checkRead method doesn't allow read access to the file, or its checkDelete method doesn't allow deleting the file when the OPEN_DELETE flag is set.
- IllegalArgumentException - if the mode argument is invalid
Since: 1.3
See Also: SecurityManager.checkRead(java.lang.String),

public ZipFile (String name) throws IOException

Opens a zip file for reading.

Methods

Hide/Show inherited methods

public void close () throws IOException

Closes the ZIP file.

public Enumeration<ZipEntry> entries ()

Returns an enumeration of the ZIP file entries.

protected void finalize () throws IOException

Ensures that the close method of this ZIP file is called when there are no more references to it.

Since the time when GC would invoke this method is undetermined, it is strongly recommended that applications invoke the close method as soon they have finished accessing this ZipFile. This will prevent holding up system resources for an undetermined length of time.
Throws:
- IOException - if an I/O error has occurred
See Also: ZipFile.close(),

public ZipEntry getEntry (String name)

Returns the zip file entry for the specified name, or null if not found.

public InputStream getInputStream (ZipEntry entry) throws IOException

Returns an input stream for reading the contents of the specified zip file entry.

public String getName ()

Returns the path name of the ZIP file.

public int size ()

Returns the number of entries in the ZIP file.
