Constructor Summary

ZipInputStream(InputStream in)

Creates a new ZIP input stream. 创建一个ZIP输入流。

Method Summary

int

available()

Returns 0 after EOF has reached for the current entry data, otherwise always return 1. 到达当前项数据的EOF后，返回0，否则总是返回1。

void

close()

Closes the ZIP input stream. 关闭ZIP输入流。

void

closeEntry()

Closes the current ZIP entry and positions the stream for reading the next entry. 关闭当前ZIP项，并将定为流以便读取下一项。

protected ZipEntry

createZipEntry(String name)

Creates a new ZipEntry object for the specified entry name. 创建一个指定项名称的ZipEntry对象。

ZipEntry

getNextEntry()

Reads the next ZIP file entry and positions stream at the beginning of the entry data. 读取下一个ZIP文件项，并把流定位在项数据的开始位置。

int

,]read(byte[] b, int off, int len)

Reads from the current ZIP entry into an array of bytes. 从当前的ZIP文件项读入字节数组。

long

skip(long n)

Skips specified number of bytes in the current ZIP entry. 跳过当前ZIP项的指定字节数。

Returns: the ZipEntry just read 刚读取的ZipEntry 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closeEntrypublic void closeEntry()

throws IOException

Closes the current ZIP entry and positions the stream for reading the next entry. 关闭当前ZIP项，并将定为流以便读取下一项。

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availablepublic int available()

throws IOException

Returns 0 after EOF has reached for the current entry data, otherwise always return 1. 到达当前项数据的EOF后，返回0，否则总是返回1。 Programs should not count on this method to return the actual number of bytes that could be read without blocking. 程序不能凭借此方法返回不阻塞条件下读取的实际字节数。

Overrides: available in class InflaterInputStreamReturns: 1 before EOF and 0 after EOF has reached for current entry. 当前项数据的EOF后，返回0，之前返回1。 Throws: IOException - if an I/O error occurs. 如果发生I/O错误抛出。readpublic int read(byte[] b,
