Method Detail

forNumbers

public static <T extends Number> Comparator<T> forNumbers()

Returns a comparator that compares numbers based on their double value.

Type Parameters:

T - The element type

Returns:

The comparator

createOrderIgnoreCase

public static Comparator<String> createOrderIgnoreCase(String... order)

Creates a comparator that compares strings according to the given order. The strings of the given order and the strings to be compared will be converted to lower case before they are compared. Strings that are not contained in the given order will be considered as "greater" than any string that is contained in the given order (and thus, be ordered after all the strings that appear in this order). Two strings that are both not contained in the given order will be considered as being equal (and thus, their sort order will not be changed for stable sorts)

Parameters:

order - The order of the strings

Returns:

The comparator that compares according to the given order
