ZipOutputStreampublic ZipOutputStream(OutputStream out)

Creates a new ZIP output stream. 创建一个ZIP输出流。

Parameters: out - the actual output stream 实际输出流Method Detail

setCommentpublic void setComment(String comment)

Sets the ZIP file comment. 设置ZIP文件注释。

Parameters: comment - the comment string 注释字符串 Throws: IllegalArgumentException - if the length of the specified ZIP file comment is greater than 0xFFFF bytes 如果指定的ZIP文件注释长度大于0xFFFF字节抛出setMethodpublic 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. 设置后续项的默认压缩方法。在未指定单个ZIP文件项的压缩方法时使用默认设置，初始设为DEFLATED。

Parameters: method - the default compression method 默认压缩方法 Throws: IllegalArgumentException - if the specified compression method is invalid 如果指定的压缩方法无效抛出setLevelpublic void setLevel(int level)

Sets the compression level for subsequent entries which are DEFLATED. The default setting is DEFAULT_COMPRESSION. 设置后续DEFLATED项的压缩级别。默认设置为DEFAULT_COMPRESSION。

Parameters: level - the compression level (0-9) 压缩级别（0-9） Throws: IllegalArgumentException - if the compression level is invalid 如果压缩级别无效抛出putNextEntrypublic 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. 开始写入一个新的ZIP文件项，并将流定位在项数据的开始。如果仍然处于活动状态，关闭当前项。如果未指定项的压缩方法，使用默认的压缩方法。如果项没有设置修改时间，则使用当前时间。

Parameters: e - the ZIP entry to be written 要写入的ZIP项 Throws: ZipException - if a ZIP format error has occurred 如果发生ZIP格式错误抛出 IOException - if an I/O error has occurred 如果发生I/O错误抛出closeEntrypublic void closeEntry()

throws IOException

Closes the current ZIP entry and positions the stream for writing the next entry. 关闭当前ZIP项，并将定位流以便写入下一项。

Throws: ZipException - if a ZIP format error has occurred 如果发生ZIP格式错误抛出 IOException - if an I/O error has occurred 如果发生I/O错误抛出writepublic 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. 将字节数组写入当前ZIP项数据。方法将阻塞直到所有字节写入。

Overrides: ,]write in class DeflaterOutputStreamParameters: b - the data to be written 要写入的数据 off - the start offset in the data 数据的起始偏移 len - the number of bytes that are written 要写入的字节数 Throws: ZipException - if a ZIP file error has occurred 如果发生ZIP文件错误抛出 IOException - if an I/O error has occurred 如果发生I/O错误抛出finishpublic 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. 完成ZIP输出流内容的写入，不关闭底层流。当在同一个输出流上连续应用多个过滤器时使用此方法。

Overrides: finish in class DeflaterOutputStreamThrows: ZipException - if a ZIP file error has occurred 如果发生ZIP文件错误抛出 IOException - if an I/O exception has occurred 如果发生I/O错误抛出closepublic void close()

throws IOException

Closes the ZIP output stream as well as the stream being filtered. 关闭ZIP输出流，同时过滤。

Overrides: close in class DeflaterOutputStreamThrows: ZipException - if a ZIP file error has occurred 如果发生ZIP文件错误抛出 IOException - if an I/O error has occurred 如果发生I/O错误抛出[/url][url=file:///F:/资料/文字资料/j2sdk-1_4_2-doc/docs/api/overview-summary.html]Overview
