o setComment(String)
Sets the ZIP file comment.
o setLevel(int)
Sets the compression level for subsequent entries.
o setMethod(int)
Sets the compression method for subsequent entries.
o write(byte[], int, int)

Methods

o setComment 
  public void setComment(String comment)
Sets the ZIP file comment.

Parameters:
comment - the comment string
o setMethod 
  public void setMethod(int method)
Sets the compression method for subsequent entries.

Parameters:
method - the new compression method to use
o setLevel 
  public void setLevel(int level)
Sets the compression level for subsequent entries.

Parameters:
level - the new compression level
o putNextEntry 
  public synchronized void putNextEntry(ZipEntry e) throws ZipException, IOException
Skips to the next ZIP file entry for writing.

Parameters:
e - the entry to be written
Throws: ZipException
if a ZIP error has occurred
Throws: IOException
if an I/O error has occurred
o closeEntry 
  public synchronized void closeEntry() throws ZipException, IOException
Closes the current ZIP entry.

o write 
  public synchronized void write(int b) throws ZipException, IOException
Writes specified byte to the current ZIP entry. This method will block until the byte is actually written.

Parameters:
b - the byte to be written
Throws: ZipException
if a ZIP error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
write in class DeflaterOutputStream
o write 
  public synchronized void write(byte buf[],
                                 int off,
                                 int len) throws ZipException, IOException
Writes an array of bytes to the current ZIP entry. This method will block until all the bytes are written.

Parameters:
buf - the bytes to be written
off - the start offset of the data
len - the length of the data
Throws: ZipException
if a ZIP error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
write in class DeflaterOutputStream
o close 
  public synchronized void close() throws ZipException, IOException
Closes the ZIP output stream.

Throws: ZipException
if a ZIP error has occurred
Throws: IOException
if an I/O error has occurred
Overrides:
close in class DeflaterOutputStream
