java.util.zip - CRC32 Class

Introduction

The java.util.zip.CRC32 class is a class that can be used to compute the CRC-32 of a data stream.

Following is the declaration for java.util.zip.CRC32 class −

public class CRC32
   extends Object
      implements Checksum

Sr.No.	Constructor & Description
1	CRC32() Creates a new CRC32 object.

Sr.No.	Method & Description
1	long getValue() Returns the CRC-32 value.
2	void reset() Resets the CRC-32 to initial value.
3	void update(byte[] b) Updates the CRC-32 checksum with the specified array of bytes.
4	void update(byte[] b, int off, int len) Updates the CRC-32 checksum with the specified array of bytes.
5	void update(int b) Updates the CRC-32 checksum with the specified byte (the low eight bits of the argument b).
