Method Detail

implode

public static java.lang.String implode(java.lang.Object[] arr,
                                       java.lang.String separator)

Parameters:

arr -

separator -

Returns:

a string of all string representations of the objects in arr, separated by separator

unsplit

public static java.lang.String unsplit(java.util.Collection<java.lang.String> set,
                                       java.lang.String separator)

Parameters:

set -

separator -

Returns:

a string of all string representations of the objects in set, separated by separator

sort

public static java.util.ArrayList sort(java.util.List list)

Parameters:

list -

Returns:

list, sorted

downloadURL

public static java.lang.String downloadURL(java.net.URL url)

loadCSV

public static double[][] loadCSV(java.io.File file)

round

public static double round(double data,
                           int numFractionDigits)

rounds a double value to a given number of digits

Parameters:

data -

numFractionDigits -

Returns:

data, rounded

addzeros

public static java.lang.String addzeros(int data,
                                        int desiredLength)

Pads integer data with leading zeros until a desired length is reached. This is useful for e.g. dates, where 2009-07-30 looks better than 2009-7-30.

Parameters:

data -

desiredLength -

Returns:

a string of length desiredLength consisting of data and a number of leading zeros
