Splits a string into compoments based on a separator String. Does what Perl's split function does, except that we don't have regular expressions built into Java.

Parameters:

delim - the delimiter.

str - the String.

Returns:

the components of the string.

join

public static java.lang.String join(java.lang.String delimiter,
                                    java.util.Collection comps)

Joins strings into a single string based on a delimeter String. Does what Perl's join function does.

Parameters:

comps - a Collection containing the Strings to join.

Returns:

the joined string.

format

public static java.lang.String format(double d)

Converts a double to a string, formatted with six digits after the decimal point.

Parameters:

d - the double.

Returns:

the formatted string representation of d.

shorten

public static java.lang.String shorten(double d)

Converts a double to a string. Removes the fractional part if it is zero.

Parameters:

d - the double.

Returns:

the formatted string representation of d.

format

public static java.lang.String format(int n,
                                      int numDigits)

Converts an integer to a string, formatted to fill at least the given number of digits.

Parameters:

n - the int.

numDigits - the number of digits.

Returns:

the string.

toCollection

public static java.util.LinkedList toCollection(java.lang.String[] args)

Converts an array of Strings to a LinkedList of strings.

Parameters:

args - the array of Strings.

Returns:

the LinkedList.

toStringArray

public static java.lang.String[] toStringArray(java.util.Collection c)

Converts a collection of Strings into an array of strings.

Returns:

the array.

toSortedStringArray

public static java.lang.String[] toSortedStringArray(java.util.Collection c)

Calls toStringArray and then sorts the result.

Returns:

the sorted result.

replace

public static java.lang.String replace(java.lang.String s,
                                       java.lang.String replace,
                                       java.lang.String with)
