The getAdler() function of the Inflater class returns the Adler-32 value of the uncompressed data. Adler-32 is a checksum algorithm which is widely used zlib compression library.
Function Signature:
public int getAdler()
Syntax:
i.getAdler();
Parameter: The function requires no parameter
Return Type: The function returns Integer value which is the Adler-32 value of the uncompressed data.
Exception: The function does not throw any exception
