- Constructor Detail
  - ZipOutputStream
```
public ZipOutputStream(OutputStream out)
```
    Creates a new ZIP output stream.
    The UTF-8 charset is used to encode the entry names and comments.
    
    Parameters:
    out - the actual output stream
  - ZipOutputStream
```
public ZipOutputStream(OutputStream out,
               Charset charset)
```
    Creates a new ZIP output stream.
    
    Parameters:
    out - the actual output stream
    charset - the charset to be used to encode the entry names and comments
    Since:
    
    1.7
- Method Detail
  - setComment
```
public void setComment(String comment)
```
    Sets the ZIP file comment.
    
    Parameters:
    comment - the comment string
    
    Throws:
    
    IllegalArgumentException - if the length of the specified ZIP file comment is greater than 0xFFFF bytes
  - setMethod
```
public void setMethod(int method)
```
    Sets the default compression method for subsequent entries. This default will be used whenever the compression method is not specified for an individual ZIP file entry, and is initially set to DEFLATED.
    
    Parameters:
    method - the default compression method
    
    Throws:
    
    IllegalArgumentException - if the specified compression method is invalid
  - setLevel
```
public void setLevel(int level)
```
    Sets the compression level for subsequent entries which are DEFLATED. The default setting is DEFAULT_COMPRESSION.
    
    Parameters:
    level - the compression level (0-9)
    
    Throws:
    
    IllegalArgumentException - if the compression level is invalid
  - putNextEntry
```
public void putNextEntry(ZipEntry e)
                  throws IOException
```
    Begins writing a new ZIP file entry and positions the stream to the start of the entry data. Closes the current entry if still active. The default compression method will be used if no compression method was specified for the entry, and the current time will be used if the entry has no set modification time.
    
    Parameters:
    e - the ZIP entry to be written
    
    Throws:
    
    ZipException - if a ZIP format error has occurred
    
    IOException - if an I/O error has occurred
  - closeEntry
```
public void closeEntry()
                throws IOException
```
    Closes the current ZIP entry and positions the stream for writing the next entry.
    
    Throws:
    
    ZipException - if a ZIP format error has occurred
    
    IOException - if an I/O error has occurred
  - write
```
public void write(byte[] b,
         int off,
         int len)
           throws IOException
```
    Writes an array of bytes to the current ZIP entry data. This method will block until all the bytes are written.
    
    Overrides:
    
    write in class DeflaterOutputStream
    
    Parameters:
    b - the data to be written
    off - the start offset in the data
    len - the number of bytes that are written
    
    Throws:
    
    ZipException - if a ZIP file error has occurred
    
    IOException - if an I/O error has occurred
    See Also:
    FilterOutputStream.write(int)
  - finish
```
public void finish()
            throws IOException
```
    Finishes writing the contents of the ZIP output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.
    
    Overrides:
    
    finish in class DeflaterOutputStream
    
    Throws:
    
    ZipException - if a ZIP file error has occurred
    
    IOException - if an I/O exception has occurred
  - close
```
public void close()
           throws IOException
```
    Closes the ZIP output stream as well as the stream being filtered.
    
    Specified by:
    
    close in interface Closeable
    
    Specified by:
    
    close in interface AutoCloseable
    
    Overrides:
    
    close in class DeflaterOutputStream
    
    Throws:
    
    ZipException - if a ZIP file error has occurred
