Method Detail

contains

public static boolean contains(java.lang.Object[] array,
                               java.lang.Object value)

Determines if the given array contains the given value.

Parameters:

array - the array to test

value - the value to test

Returns:

true if the given array contains the given value or
false, otherwise

contains
