public class ZipInputStream
extends InflaterInputStream
implements ZipConstants
This class implements an input stream filter for reading files in the ZIP file format. Includes support for both compressed and uncompressed entries.

Constructor Index

o ZipInputStream(InputStream)
Creates a new ZIP input stream.

Method Index

o close()
Closes the ZIP input stream.
o closeEntry()
Closes the current ZIP entry and positions the stream for reading the next entry.
o createZipEntry(String)
Creates a new ZipEntry object for the specified entry name.
o getNextEntry()
Reads the next ZIP file entry and positions stream at the beginning of the entry data.
o read(byte[], int, int)
Reads from the current ZIP entry into an array of bytes.
o skip(long)
Skips specified number of bytes in the current ZIP entry.

Constructors

o ZipInputStream 
public ZipInputStream(InputStream in)
Creates a new ZIP input stream.

Parameters:
in - the actual input stream

Methods

o getNextEntry 
public ZipEntry getNextEntry() throws IOException
Reads the next ZIP file entry and positions stream at the beginning of the entry data.

Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
o closeEntry 
public void closeEntry() throws IOException
Closes the current ZIP entry and positions the stream for reading the next entry.

Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
o read 
public int read(byte[] b,
                int off,
                int len) throws IOException
Reads from the current ZIP entry into an array of bytes. Blocks until some input is available.

Parameters:
b - the buffer into which the data is read
off - the start offset of the data
len - the maximum number of bytes read
Returns:
the actual number of bytes read, or -1 if the end of the entry is reached
Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
read in class InflaterInputStream
o skip 
public long skip(long n) throws IOException
Skips specified number of bytes in the current ZIP entry.

Parameters:
n - the number of bytes to skip
Returns:
the actual number of bytes skipped
Throws: ZipException
if a ZIP file error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
skip in class InflaterInputStream
o close 
public void close() throws IOException
Closes the ZIP input stream.

Throws: IOException
if an I/O error has occurred
Overrides:
close in class FilterInputStream
o createZipEntry 
protected ZipEntry createZipEntry(String name)
