## 31.5 java.util.zip.CRC32 (JDK 1.1)

###

This class implements the `Checksum` interface and computes a checksum on a stream of data using the CRC-32 algorithm. The `CheckedInputStream` and `CheckedOutputStream` classes provide a higher-level interface to computing checksums on streams of data.

    public class CRC32 extends Object implements Checksum {
        // Default Constructor: public CRC32()
        // Public Instance Methods
                public long getValue();  // From Checksum
                public void reset();  // From Checksum
                public void update(int b);  // From Checksum
                public native void update(byte[] b, int off, int len);  // From Checksum
                public void update(byte[] b);
    }
