java.util.zip.Inflater类使用流行的ZLIB压缩库为通用解压缩提供支持。 ZLIB压缩库最初是作为PNG图形标准的一部分开发的，不受专利保护。在java.util.zip软件包说明中的规范中对其进行了全面描述。
以下是java.util.zip.Inflater类的声明-
public class Inflater
extends Object
| Sr.No. | Constructor & Description |

| Sr.No. | Method & Description |
|---|---|
| 1 | void end()
Closes the decompressor and discards any unprocessed input. |
| 2 | boolean finished()
Returns true if the end of the compressed data stream has been reached. |
| 3 | int getAdler()
Returns the ADLER-32 value of the uncompressed data. |
| 4 | long getBytesRead()

| 11 | boolean needsDictionary()
Returns true if a preset dictionary is needed for decompression. |
| 12 | boolean needsInput()
Returns true if no data remains in the input buffer. |
| 13 | void reset()
