Method Detail

main

public static void main(java.lang.String[] args)

This method is for stand-alone testing purpose only. It prints out the CheckSum of the requested file in args[0].

Parameters:

args[0] - :: The path of the file whose CheckSum needs to be determined.

GetFileCheckSum

public static long GetFileCheckSum(java.lang.String strFilePath)
                            throws java.io.IOException

This method tries to find and return the CheckSum of a file.

Parameters:

strFileName - :: The path of the file whose CheckSum needs to be determined.

Returns:

:: Returns the CheckSum of the file if successfull, otherwise it returns "-1" or throws an exception.

Throws:

java.io.IOException

CompareFileCheckSum

public static boolean CompareFileCheckSum(java.lang.String strFilePath,
                                          long nCompareValue)
                                   throws java.io.IOException

This method tries to compare the checksum of the file requested with the .

Parameters:

strFileName - :: The path of the file whose CheckSum needs to be determined and compared.

nCompareValue - :: The value against which to compare the file's CheckSum.

Returns:

:: Returns true if the file's checksum is equals to the compare value, otherwise returns false.

Throws:

java.io.IOException

CompareCheckSumOfFiles

public static boolean CompareCheckSumOfFiles(java.lang.String strFilePath_1,
                                             java.lang.String strFilePath_2)
                                      throws java.io.IOException

This method tries to compare the checksums of two files.

Parameters:

strFilePath_1 - :: The path of the first file whose CheckSum needs to be determined and compared.

strFilePath_2 - :: The path of the second file whose CheckSum needs to be determined and compared.

Returns:

:: Returns true if the checksum of both files is equal, otherwise returns false.

Throws:

java.io.IOException
