public class SplitFile

extends java.lang.Object

This program provides a mechanism to easily split a text file into multiple files based on a number of criteria (specific number of files, number of lines per file, or number of bytes per file).

Field Summary

static int	SPLIT_TYPE_NUM_BYTES The split type that indicates the file should be split up so that there are a maximum number of bytes per file.
static int	SPLIT_TYPE_NUM_FILES The split type that indicates the file should be split up into a specific number of files.
static int	SPLIT_TYPE_NUM_FILES_PRESERVE_ORDER The split type that indicates the file should be split up into a specific number of files.
static int	SPLIT_TYPE_NUM_LINES The split type that indicates the file should be split up so that there are a maximum number of lines per file.

Constructor Summary

SplitFile(java.lang.String[] args)
Creates a new instance of this program and coordinates the process of splitting the file.

Method Summary

int	countLines() Counts the number of lines in the input file.
void	displayUsage() Prints usage information for this program to standard error.
static void	main(java.lang.String[] args) The main method for this program, which simply invokes the constructor.
void	splitByMaxBytes() Splits the input file into a number of output files based on the number of bytes per file.
void	splitByMaxLines() Splits the input file into a number of output files based on the number of lines per file.
void	splitToNumFiles() Splits the input file into the specified number of output files.
